How to Calculate Holiday Let Yield Properly
A summer week in Falmouth can command a very different rate from a quiet Tuesday in January. That is why learning how to calculate holiday let yield properly means looking beyond an attractive nightly price or a busy August calendar. The useful figure is the one that reflects what your property actually earns across a full year, after the costs of welcoming guests have been paid.
For second-home owners and investors in Cornwall, yield is a practical way to judge performance. It helps you compare a holiday let with a long-term tenancy, decide whether planned improvements are worthwhile, and set realistic expectations before buying or launching a property. It also gives you a clearer basis for conversations with a management company, rather than relying on headline revenue alone.
Start with gross holiday let yield
Gross yield is the quickest calculation. It compares your annual booking income with the property’s total value or purchase cost.
Gross yield = annual gross rental income ÷ property value × 100
Say a Falmouth property is worth £400,000 and produces £48,000 in accommodation revenue over a year. The gross yield is:
£48,000 ÷ £400,000 × 100 = 12%
This is a useful first indication, particularly when comparing several properties. However, gross yield does not tell you what remains in your pocket. A well-presented coastal home can bring in strong revenue while carrying substantial cleaning, utilities, maintenance and management costs. Treat gross yield as a starting point, not the final decision-maker.
There is also a choice to make over the value used in the calculation. If you are assessing a potential purchase, use the full acquisition cost: purchase price, stamp duty, legal fees, surveys, furnishing and any essential refurbishment. If you already own the property, use its current market value when comparing it with other investment options. Either approach can be valid, but be consistent so the numbers remain meaningful.
How to calculate holiday let yield after costs
Net yield is normally the more useful measure for an owner. It uses annual income after operating expenses.
Net yield = annual rental income minus annual operating costs ÷ property value × 100
Using the same £400,000 property, imagine annual revenue of £48,000 and annual running costs of £18,000. The calculation is:
£48,000 - £18,000 = £30,000 net operating income
£30,000 ÷ £400,000 × 100 = 7.5% net yield
That 7.5% is a much more honest view of the property’s operating return before finance costs and tax. It shows why two lets with similar annual revenue may perform very differently. One may have a lower cleaning burden, a more efficient heating system, better direct-booking potential or a stronger rate throughout the shoulder seasons.
For a complete calculation, include the costs that genuinely arise from running the home as a short-term let. These commonly include management fees, cleaning and laundry, utilities, council tax or business rates where applicable, insurance, platform fees, maintenance, gardening, consumables, linen replacement, broadband, accounting and marketing. If you pay for a changeover team or use a keyholding service, those costs belong in the figure too.
Avoid assuming that guest-paid cleaning is pure profit. Even where a cleaning charge is collected separately, it should be matched against what the clean and linen service actually costs. The same applies to damage deposits and security holds: they are not rental income unless a genuine charge is retained.
Build the income forecast from occupancy and rate
A reliable yield forecast begins with two numbers: average daily rate and occupancy. Average daily rate, often shortened to ADR, is the average income earned per occupied night. Occupancy is the percentage of available nights that are booked.
For example, a property available for 300 nights of the year with 210 booked nights has 70% occupancy. If its average daily rate is £180, annual accommodation income would be:
210 booked nights × £180 = £37,800
The important word is average. Cornwall’s holiday-let market is seasonal. A home that earns £300 per night in school holidays may achieve far less during winter weekdays. Build your forecast by month, or at least by season, rather than multiplying a peak-season rate across the year.
A simple seasonal forecast might allow for higher rates and fuller calendars from late spring through early autumn, then lower rates and lighter demand in winter. Christmas, New Year, half terms and local events can create valuable exceptions. A property near Falmouth town centre, the beach, the university or popular wedding venues may also have demand patterns that differ from a rural cottage a few miles inland.
Your own use matters as well. If you block three weeks in August for family holidays, those are nights the property cannot sell at its strongest rates. This does not make owner stays a bad decision - one of the pleasures of a second home is using it - but they need to be recognised when measuring investment performance. Calculate yield based on the income you can realistically earn from the nights you make available.
Do not confuse revenue with profit
Holiday lets can show impressive top-line revenue because guests pay higher nightly rates than long-term tenants. They also require more active care. Guests expect fresh linen, quick responses, spotless presentation and prompt solutions when something goes wrong. Those standards protect reviews and future booking performance, but they have a cost.
A lower management fee is not automatically the better commercial choice if it results in weaker photography, poorly managed pricing, missed enquiries or inconsistent guest reviews. Equally, a high revenue estimate should be questioned if it assumes peak pricing every weekend or overlooks winter demand. The aim is not to find the largest projected number. It is to use assumptions that are credible for your location, property type and level of presentation.
When comparing management options, ask what is included and what sits outside the quoted percentage. Cleaning coordination, laundry, guest communications, pricing management, photography, listing set-up, maintenance oversight and owner reporting can all affect the true cost and the result. Transparent reporting makes it easier to see the relationship between occupancy, nightly rate, costs and net income over time.
Factor in finance and tax separately
Net operating yield is not the same as your personal return after mortgage payments and tax. Mortgage interest, capital repayments and tax treatment depend on your ownership structure and circumstances. These should be considered separately with a qualified accountant or financial adviser.
For cash-flow planning, it can still be helpful to calculate a further measure: annual net operating income minus mortgage payments. This shows whether the property is contributing cash each month, particularly through quieter periods. But do not label this as property yield without making clear that finance has been included. Two owners can have the same holiday let yield and very different cash positions because their borrowing is different.
Tax rules and eligibility for any holiday-let-related reliefs can change, so avoid basing a purchase decision on assumptions from a previous tax year. Good record-keeping is worth the effort from day one. Keep invoices, booking statements, utility bills, maintenance records and a clear record of personal stays.
Use yield to improve the property, not just judge it
Once you know the baseline, yield becomes a practical management tool. A bathroom refresh, better outdoor seating, pet-friendly features or professional photography may increase bookings or support a stronger nightly rate. But every improvement should be tested against its cost and likely impact.
If a £5,000 upgrade is expected to add £3,000 a year in net income, that is a different proposition from one that simply makes the property look nicer without shifting guest demand. Some upgrades also reduce operating costs. Efficient heating, sensible lighting controls and durable furnishings can protect both margins and guest comfort over the long term.
Review performance monthly, but judge success over a full year. A wet spring, a local festival, changes in transport or a late burst of summer bookings can distort a single month. Look at booked nights, achieved rate, revenue per available night, guest feedback and maintenance spend together. This gives you a better picture than occupancy alone.
A local team can be particularly valuable here because pricing is not only about broad Cornwall averages. It is about what comparable homes in your part of Falmouth are achieving for a particular weekend, how quickly dates are booking, and what guests value in that location. At Guested, that local knowledge is paired with clear owner reporting, so owners can keep sight of earnings while retaining time to enjoy their homes.
Before you commit to a purchase, refurbishment or new management arrangement, build a cautious forecast alongside your optimistic one. If the property still works when occupancy is lower, rates soften and a repair bill arrives, you have a far sounder foundation for a holiday let that performs well and remains enjoyable to own.
