What Occupancy Makes a Holiday Let Profitable?

A listing showing £45,000 of annual gross income can look compelling until you ask how many nights must actually be sold to produce it. The question, “what occupancy makes holiday let profitable”, is therefore less about finding a universal percentage and more about exposing the assumptions behind a particular property.

A coastal cottage with modest borrowing may work at 45% occupancy. A highly leveraged lodge with expensive site fees may need 70% or more. Neither figure means much without the nightly rate, operating model, available booking nights and cost base sitting behind it.

For a buyer, the useful number is break-even occupancy: the proportion of sellable nights required for income to cover the costs you have chosen to include. Once you know that figure, you can judge whether the market evidence supports it and whether there is enough room for a weak year.

What occupancy makes a holiday let profitable?

A holiday let is not automatically profitable once it covers its mortgage. Nor is it necessarily a good investment simply because it produces a positive cash surplus. Before calculating occupancy, be clear about the definition you are using.

Operational break-even means rental income covers running costs before finance. Cashflow break-even includes mortgage payments and shows whether the property is likely to need money put into it during the year. A fuller investment assessment also considers furnishing, purchase costs, void periods, major repairs, tax and the return on your cash invested.

For most acquisition decisions, cashflow break-even is the more practical starting point. It answers a simple but important question: how full does the calendar need to be before the property stops consuming cash? It should not be the finish line. A deal that only works at break-even has no allowance for disruption, repairs or lower-than-expected rates.

Calculate break-even occupancy from the actual costs

The basic calculation is straightforward:

Break-even occupancy = annual fixed costs ÷ (available nights × contribution per occupied night)

Contribution per occupied night is the average nightly rate left after the costs that rise when a guest stays. Those may include booking commissions, payment processing, cleaning and laundry, utilities, guest consumables and management charges where they are calculated as a percentage of bookings.

Fixed annual costs are the expenses you expect to pay whether the property is occupied or empty. They can include mortgage payments, insurance, council tax or business rates, broadband, licence or compliance costs, accounting, marketing subscriptions, site fees and an allowance for maintenance.

The distinction is not always perfect. Cleaning, for example, is often charged per stay rather than per night. Convert it to a nightly figure using a realistic average length of stay. A £75 clean over a three-night booking costs £25 per occupied night; over a seven-night booking it costs closer to £11. If your local market relies on short breaks, this difference can materially change the result.

Worked example: a three-bedroom cottage

Assume a cottage achieves an average realised nightly rate of £165 across the whole year. This is not its peak August price. It is the weighted average after quieter months, offers and any discounting required to fill gaps.

| Assumption | Amount | | — | —: | | Average nightly rate | £165.00 | | Booking commission at 15% | £24.75 | | Utilities and consumables per occupied night | £12.00 | | Cleaning and linen per night, based on three-night stays | £25.00 | | Contribution per occupied night | £103.25 | | Annual fixed costs, including mortgage payments | £20,000 |

The property needs roughly 194 occupied nights to cover £20,000 of fixed costs (£20,000 ÷ £103.25). Across 365 available nights, that is a break-even occupancy of 53%.

At 60% occupancy, it would sell about 219 nights. The estimated contribution would be around £22,617, leaving only £2,617 after the fixed costs. That is positive cashflow, but it is not a generous buffer for replacement furniture, storm damage, a boiler failure or a softer booking year. At 45% occupancy, contribution falls to about £16,933, leaving an annual shortfall of roughly £3,067 before tax and larger capital items.

The lesson is not that 53% is a bad figure. In a strong, evidenced location it may be achievable. The point is that a single headline revenue number does not show how little margin may remain after realistic costs.

Why headline occupancy can mislead buyers

Occupancy is only meaningful when paired with average daily rate. A property at 70% occupancy with an average rate of £95 may generate less usable income than one at 50% occupancy with a rate of £175. It is revenue per available night, and ultimately contribution per available night, that pays the bills.

Seasonality makes this more pronounced. Many UK holiday lets can fill school holidays at attractive prices, then struggle to secure midweek winter bookings. A forecast built from peak-week rates and a flat annual occupancy percentage often hides this pattern. Model the year by month or at least by season where possible, using different rates and occupancy assumptions for each period.

Availability also needs scrutiny. A 60% occupancy figure may be calculated against all 365 days, but an owner who blocks six weeks for personal use has fewer nights available to earn income. Conversely, planned closure for refurbishment or low-season maintenance may be sensible, but it should be reflected in the model rather than treated as a surprise.

Finance is another common source of false comfort. A cash buyer and a buyer using a repayment mortgage can own identical cottages yet face very different break-even points. Include the actual expected mortgage payment in a cashflow model, then test the effect of higher interest rates if the borrowing is not fixed for the full period you are assessing.

Set a target above break-even, not at it

A sensible target occupancy is the rate that produces a worthwhile surplus after costs, not simply a zero balance. You can calculate it by replacing fixed costs in the formula with fixed costs plus your desired annual cash surplus.

Using the cottage example, a £10,000 pre-tax cashflow target would require approximately 290 occupied nights at the same £103.25 contribution per night. That is close to 80% occupancy, which should prompt a harder question: is the nightly rate too low, are costs too high, is the finance too aggressive, or is this simply not the right deal?

Before making an offer, run at least four cases:

• a base case based on conservative local evidence rather than an agent’s best year;
• a downside case with lower occupancy and a reduced average nightly rate;
• a cost-stress case allowing for higher utilities, repairs, commission or finance costs; and
• an upside case, kept separate from the decision-making case rather than used to justify the purchase.

The downside case is particularly useful. If a property requires 68% occupancy just to break even and comparable evidence suggests 55% is more normal, the issue is visible early. You may be able to negotiate the price, reduce borrowing or walk away before spending heavily on surveys, legal work and furnishing.

Check the market evidence behind the percentage

Do not accept occupancy claims without understanding their source. Ask whether figures refer to booked nights divided by all calendar nights or only nights made available. Establish whether the income includes cleaning fees, VAT where relevant, owner stays or other units in a portfolio. A large operator’s portfolio average may not translate to one individual cottage in a different location or condition.

Look at comparable properties with similar guest capacity, quality, pet policy and proximity to the actual demand driver. A lodge beside a popular attraction should not be benchmarked against a distant cottage merely because both sleep six. Read guest calendars and reviews for clues on booking patterns, minimum stays, lead times and the months that appear difficult to fill.

Then work from the property’s likely position in the market, not from the most optimistic comparable. New listings may need introductory pricing and time to build reviews. Properties that require frequent short stays may have stronger gross occupancy but higher cleaning and management costs. A hands-off management arrangement may lower your workload but reduce contribution per booking.

Use occupancy as a decision tool

Break-even occupancy should be visible in every holiday-let appraisal alongside annual revenue, mortgage costs and net cashflow. It turns a broad promise of “strong demand” into a measurable requirement: this property needs this many booked nights, at this average rate, after these costs.

If the required figure is comfortably below your conservative market case, the deal may deserve deeper due diligence. If it sits close to, or above, the evidence-based forecast, do not try to solve the problem with optimism. Adjust the price, funding structure or operating assumptions until the risk is clear. The best holiday-let purchase is often the one that can withstand an ordinary year, not just a fully booked one.
