Airbnb Investment Calculator UK — ROI, Yield and Monthly Returns

Last updated: July 2026

This UK Airbnb investment calculator shows the ROI, gross yield, net yield, and monthly cash flow on a property purchase for short-term letting — so you can see whether the numbers stack up before committing.

It's designed for buyers who have already found a property and want to validate the investment case with honest figures — not for buyers who want to be told the numbers work.

If you haven't yet estimated what the property would earn, use the income calculator first — then enter that net income figure here.

The most important output is not gross yield — it is monthly cash flow after the mortgage payment, which determines whether the investment is sustainable in a slower month.

Quick answer

An Airbnb investment calculator models whether a UK property purchase makes financial sense for short-term letting — by combining expected monthly net income with purchase price, deposit, mortgage, and running costs to show annual ROI, gross and net yield, and monthly cash flow. Enter your property details below to see whether the numbers stack up before committing to a purchase.

On the income figure feeding this calculator

We don't guarantee a fixed income figure — and we'd be cautious of any company that does.

What we show you is the realistic range, including quieter months, based on comparable properties in your postcode. Even in a slower year, the net figure typically exceeds what a long-term tenancy would pay.

The gap between gross yield and what you actually clear each month — why developer figures rarely reflect reality

How do I calculate Airbnb yield on a UK property?

Gross yield is annual gross STR income divided by purchase price, times 100. Net yield does the same with income after all running costs, before the mortgage. Cash-on-cash return divides annual cash flow after the mortgage by your deposit. Net yield and cash-on-cash are the two that matter for a real decision — gross yield alone tells you nothing about whether the deal is cashflow positive.

Gross yield is the figure most commonly used to market UK investment properties for short-term letting.

It is calculated by dividing annual gross booking revenue by the purchase price.

It tells you nothing about whether the investment generates positive cash flow.

EXPERT INSIGHT

Developer projections for holiday let properties often show gross yields of 8–12%.

After mortgage, management fees, and running costs, the actual cash-on-cash return on a typical UK property is 3–8% — and can be negative on overleveraged or poorly located purchases.

The gap between the headline figure and the real return is almost always cleaning, void periods, and the mortgage cost — three things that are routinely omitted from developer-provided cashflow projections.

Metric What it measures Typical range (UK STL) What it misses
Gross yield Annual gross revenue ÷ purchase price 6–12% Platform fees, management, cleaning, running costs, mortgage
Net yield Annual net income after costs ÷ purchase price 4–8% Mortgage — whether the investment is cashflow positive
Cash-on-cash return Annual cash flow after mortgage ÷ deposit 3–8% Capital appreciation — the total return picture
Monthly cash flow Net income − mortgage − running costs £0–£600 typical The figure that determines whether you can sustain a quiet month

Monthly cash flow is the metric that matters most for sustainability.

A property generating 8% gross yield but negative monthly cash flow requires the owner to fund the shortfall every month — which becomes critical in quieter periods when STR income falls.

How to calculate holiday let yield — the two formulas, and which one lenders actually ask for

The two formulas

Gross yield is annual gross revenue divided by purchase price, times 100. Net yield is annual net income after all operating costs divided by total capital invested, times 100. On a short-let property the two typically differ by 4–6 percentage points, which is why a listing advertising "11% yield" and an owner reporting 6% can both be describing the same property honestly.

Gross yield is the figure used in property listings and developer brochures, because it is the larger one.

Net yield is the figure that tells you whether the deal works.

MeasureFormulaWorked example
Gross yield (Annual gross revenue ÷ purchase price) × 100 £28,944 ÷ £250,000 = 11.6%
Net yield (Annual net income ÷ purchase price) × 100 £17,868 ÷ £250,000 = 7.1%
Net yield on total capital (Annual net income ÷ total cash invested) × 100 £17,868 ÷ £97,500 = 18.3%

Illustrative worked example on a £250,000 property at 25% deposit — not a projection for any specific purchase.

The third row is cash-on-cash return, and it is the figure that matters most if you are buying with a mortgage, because it measures the return on money you have actually committed rather than on the headline property value.

Which one to use Lenders assessing a holiday let mortgage generally want gross annual revenue against the loan, stress-tested at a higher interest rate than you will initially pay. Investors comparing one deal against another should use net yield on total capital invested, because it is the only measure that accounts for the deposit, stamp duty and refurbishment you have sunk into the property. Gross yield is useful for one thing only — quickly discarding deals that cannot possibly work.

A short-let property with a gross yield below roughly 8% rarely survives the deduction of platform fees, management, cleaning, utilities and voids into a net figure worth pursuing.

That is a screening threshold rather than a target, and it varies by region and property type.

How to tell if the deal makes sense — three tests before you commit to a purchase

What's a good ROI for an Airbnb property in the UK?

A cash-on-cash return of 5–8% after all costs including the mortgage is a strong result for a UK short-let property in 2026. Most well-chosen properties at current interest rates produce 3–6% — modest as a cash figure, but typically well ahead of the same property on a long-term tenancy, and before any capital appreciation. Gross yield above 10% should be stress-tested against real occupancy and costs before you trust it.

Run the calculator three times before deciding whether a property makes sense as an Airbnb investment.

  • Test 1 — Can it survive the quiet months? Enter the income figure for January or February — typically 40–55% of the annual average monthly figure. If monthly cash flow turns negative at that income level, the deal requires you to fund the shortfall every slow month. That may be acceptable — but you need to know before committing.
  • Test 2 — What does the cash-on-cash return look like vs alternatives? Compare the calculator's cash-on-cash figure against a long-term tenancy on the same property. If the STL cash-on-cash is lower than what a long-let would produce on the same deposit, the investment case depends on capital appreciation alone — a different thesis.
  • Test 3 — Does the deal survive a 10% income drop? Reduce the monthly income figure by 10% and recalculate. If cash flow collapses on a small income reduction, the deal is fragile. Robust deals remain cashflow positive with a 10–15% income reduction applied.
EXPERT INSIGHT

Interest-only mortgages are standard for buy-to-let investors because they maximise monthly cash flow.

On a £250,000 property with a 25% deposit and 5.5% interest rate, the monthly interest-only payment is £859.

On a repayment basis over 25 years, the same mortgage costs £1,145 per month — a £286 difference that directly determines whether the investment generates positive or negative cash flow.

Most STL investment calculators should be run on interest-only first to assess the cash flow case, then on repayment to understand the true monthly commitment if the lender requires it.

Every input explained — what to enter, and where to get a figure you can trust

An ROI calculation is only as good as the numbers you feed it, and most of the inputs that get guessed are the ones that decide whether the deal works.

Below is each input, what it means, and where to source a realistic figure rather than an optimistic one.

InputWhat it meansWhere to get a realistic figure
Purchase price Agreed price, not asking price. Land Registry sold prices for the street, not portal listings.
Deposit Cash you put in. Holiday let mortgages typically need 25–30%. A holiday-let-specific broker. Standard BTL terms do not apply.
Stamp duty The 5% additional dwelling surcharge applies on top of standard rates. HMRC SDLT calculator. See the note below — this is the input most often understated.
Refurbishment and furnishing Everything needed to reach lettable standard, including furniture, linen and kitchen equipment. Quotes, not estimates. A two-bed to short-let standard is rarely under £8,000–£15,000.
Legal, survey and Land Registry Conveyancing, searches, survey and registration. Solicitor quote. Budget £2,000–£3,500 on a typical purchase.
Average nightly rate Blended across the whole year, not the peak-season figure. Comparable managed properties in the same postcode — not the top three listings on Airbnb.
Occupancy Occupied nights as a share of nights available. UK market average is 55%. Well-managed properties reach 65–70%. Anything above 75% needs justifying.
Management fee What the management company takes. Stayful is 15% + VAT plus £42/month + VAT. The market runs 18–25% + VAT.
Running costs Utilities, broadband, insurance, council tax or business rates, consumables. Actual bills for a comparable property. Short lets use more energy than tenanted ones.
Mortgage interest Monthly interest, not capital repayment, if comparing to a cash purchase. Broker illustration. Stress-test 2 percentage points above your offered rate.
Stamp duty The additional dwelling surcharge rose from 3% to 5% on 31 October 2024, and the standard nil-rate threshold reverted to £125,000 on 1 April 2025. The surcharge applies to the entire purchase price above £40,000, added to every band — not only to the portion above £125,000. On a £300,000 buy-to-let in England that is £20,000 of SDLT; on £500,000 it is £37,500. It cannot be added to the mortgage and is payable within 14 days of completion, so it has to come from cash reserves. Many online yield calculators were built before the increase and still apply 3%. Confirm your figure with the HMRC calculator and your solicitor — these rules apply to England and Northern Ireland only.
The input that breaks most models Occupancy. Moving occupancy from 55% to 75% in a spreadsheet raises annual revenue by roughly 36% and can turn a marginal deal into an apparently excellent one — on paper. It is the easiest input to inflate and the hardest to actually achieve. Stayful-managed properties average 65–70% against a UK market average of 55%, and that gap comes from dynamic pricing, multi-platform listing and a direct booking channel carrying 40% of bookings. Model at 60–65% if the property will be professionally managed, and at 50–55% if you intend to self-manage.

Void periods between guests are already reflected in the occupancy figure, so do not deduct them twice.

Capital growth is deliberately excluded from every calculation on this page — it is speculative, and a deal that only works with assumed appreciation is not a deal that works.

What the numbers look like for a well-chosen UK short-let property — honest worked example

Should I use interest-only or repayment for an Airbnb investment?

Most buy-to-let investors use interest-only, because it maximises monthly cash flow — the figure that determines whether the investment survives a quiet month. On a £165,000 loan at 5.5%, interest-only costs £756/month against roughly £1,000/month on a 25-year repayment basis. That gap alone can turn a marginal deal negative. Availability depends on your lender and circumstances — confirm with a buy-to-let mortgage broker.

The following example uses a two-bedroom property in a UK city at conservative occupancy and a 25% deposit.

All figures are illustrative — run the calculator above with your specific property details for an accurate result.

Input / OutputConservative scenarioExpected scenario
Purchase price£220,000£220,000
Deposit (25%)£55,000£55,000
Loan£165,000£165,000
Interest-only mortgage (5.5%)£756/month£756/month
Monthly net STR income (Stayful)£1,200£1,450
Monthly running costs£370£370
Monthly cash flow£74£324
Annual cash flow£888£3,888
Gross yield6.5%7.9%
Net yield (before mortgage)4.5%5.9%
Cash-on-cash return1.6%7.1%

The conservative scenario produces a thin but positive cash flow of £74/month.

In the quietest month, income drops to approximately £540–£660 — producing negative cash flow of around £100–£200, which the owner must fund.

The expected scenario produces £324/month positive cash flow, remaining positive even in a quiet month at 45% occupancy.

Neither scenario produces a high cash-on-cash return — short-let property investment returns most of its value through income uplift over long-let (not yield alone) and through capital appreciation over the hold period.

WHAT A QUIET MONTH DOES TO CASH FLOW

In the conservative scenario above, the quietest month drops income to roughly £540–£660 — turning a thin £74/month positive cash flow into a £100–£200/month shortfall the owner has to fund.

In the expected scenario, the same quiet month stays cash flow positive, because the £324/month typical buffer absorbs the drop.

This is the real test of a deal, not the annual average: can the property still cover its mortgage and running costs in January and February, or does it depend on the strong months to bail out the weak ones.

EXPERT INSIGHT

The 70-day occupancy threshold for maintaining business rates status (rather than council tax) means the property needs genuine, sustained demand throughout the year — not just a strong summer.

The income calculator at /airbnb-income-calculator shows which postcode areas have sufficient year-round demand to sustain the 70-day let threshold comfortably.

Areas where the conservative estimate still shows strong income — such as university cities, major employment centres, and heritage towns — are more suitable for investment than seasonal leisure-only locations where the winter period may not meet the threshold.

The questions UK investors ask when they first see the real ROI figure

  • A cash-on-cash return of 5–8% after all costs including mortgage is a strong result for a UK short-let property in 2026.

    Most well-chosen properties at current interest rates produce 3–6% cash-on-cash — modest on a cash return basis, but typically significantly better than the same property on a long-term tenancy, and before any capital appreciation is factored in.

    Properties showing gross yield above 10% should be stress-tested against realistic occupancy and cost assumptions — the gap between gross yield and actual cash return is usually larger than buyers expect.

  • Most buy-to-let investors use interest-only because it maximises monthly cash flow — which is the figure that determines whether the investment is sustainable across quiet months.

    On a £165,000 loan at 5.5%, interest-only costs £756/month versus £1,008/month on repayment over 25 years — a £252 difference that can turn a marginally positive investment into a negative one.

    Whether interest-only is available depends on the lender and your circumstances. Always confirm with a mortgage broker who specialises in buy-to-let.

  • For well-chosen properties in locations with genuine year-round demand, yes — short-let generates materially higher net income than long-let on the same property, which offsets higher running costs and management fees.

    For properties in seasonal-only locations, overleveraged at current interest rates, or in areas without consistent demand, the case is much weaker.

    The calculator above shows whether your specific property and purchase structure produces positive cash flow. If it doesn't at conservative income assumptions, the investment relies on capital appreciation — which is a different and less predictable thesis.

  • Most buy-to-let lenders require a minimum 25% deposit, though some products allow 20%.

    Holiday let mortgages — which specifically allow short-term letting — typically require 25% and apply an affordability stress test based on projected rental income rather than personal income.

    Standard residential mortgages do not permit short-term letting — using one on a property you intend to Airbnb is a breach of your mortgage terms. Always confirm your mortgage type before proceeding.

  • Gross yield: (annual gross STR income ÷ purchase price) × 100.

    Net yield: (annual net income after all costs, before mortgage ÷ purchase price) × 100.

    Cash-on-cash return: (annual cash flow after mortgage and all costs ÷ deposit amount) × 100.

    The calculator above produces all three figures automatically based on your inputs. Net yield and cash-on-cash are the two that matter for investment decisions — gross yield alone is not a reliable indicator of investment performance.

  • Every guest is ID-verified before check-in, and every booking managed by Stayful is covered by £100,000 insurance alongside a £200 security deposit.

    Property inspections between stays catch issues early — worth factoring in as part of the running-cost assumptions in the calculator above if you plan to use full management.

  • Gross yield is annual gross revenue divided by purchase price, times 100. Net yield is annual net income after operating costs divided by purchase price, times 100.

    On a short-let property the two typically differ by 4–6 percentage points. If you are buying with a mortgage, the more useful measure is net income divided by total cash invested — deposit, stamp duty, legal fees and refurbishment — which gives cash-on-cash return.

  • In England and Northern Ireland an additional dwelling attracts the standard residential rates plus a 5% surcharge, which rose from 3% on 31 October 2024. The surcharge applies to the whole purchase price above £40,000, not just the portion above the £125,000 nil-rate threshold.

    On a £300,000 purchase that is £20,000 in total. On £500,000 it is £37,500. It cannot be added to the mortgage and is due within 14 days of completion.

    Scotland and Wales operate separate regimes. Confirm your figure with the HMRC calculator and your solicitor.

  • Model at 60–65% if the property will be professionally managed, and 50–55% if you intend to self-manage. The UK market average is 55%.

    Stayful-managed properties average 65–70%, driven by dynamic pricing, listing across five platforms and a direct booking channel that carries 40% of bookings. Modelling above 75% is the most common way an unworkable deal comes to look viable on a spreadsheet.

  • Furnishing a two-bedroom property to short-let standard is rarely under £8,000–£15,000 once you include furniture, mattresses, linen sets, kitchen equipment, smart locks and soft furnishings.

    Short lets are judged on presentation in a way tenanted properties are not — photography quality and finish directly affect the nightly rate you can command. Get quotes rather than estimating, and treat this as capital invested when calculating cash-on-cash return.
