Breakeven occupancy is the share of nights you must fill just to cover your rent to the landlord and the fixed bills, after booking fees, cleaning and per-night costs. You work it out as fixed monthly costs divided by what each month would earn, after variable costs, if every night were booked. In our worked example, a flat rented at £950 a month needs 49.4% occupancy to break even.
It's the number that tells you whether a rent-to-SA (rent-to-serviced-accommodation) deal can survive a quiet season. Forecasts tend to assume a healthy occupancy, but the rent and bills are due whether guests turn up or not. The gap between your realistic occupancy and breakeven is your safety margin.
Key Takeaways
- Breakeven occupancy = fixed monthly costs ÷ (full-occupancy income minus full-occupancy variable costs).
- Our rent-to-SA example breaks even at 49.4% occupancy and makes £612 a month at 72%.
- Aim for plenty of headroom between breakeven and the occupancy similar local listings actually achieve.
- Negotiating the rent is the fastest lever: here every £100 off the rent lowers breakeven by about 3.7 percentage points.
- Set-up costs aren't part of breakeven occupancy, so check the payback period as well.
What is breakeven occupancy in rent-to-SA?
In a rent-to-SA deal you rent a property from a landlord on a fixed monthly rent, with written permission to let it as serviced accommodation: short stays for tourists, contractors or business travellers. Your income depends on how many nights you fill and at what price. Your rent and bills don't.
Breakeven occupancy is the point where income after variable costs exactly covers those fixed costs. Below it you lose money every month; above it every extra booked night is mostly profit. It works like a shop's breakeven sales figure, only measured in nights.
How do you calculate breakeven occupancy?
The formula is:
Breakeven occupancy = Fixed monthly costs ÷ (Full-occupancy income − Full-occupancy variable costs)
Step 1: Add up your fixed monthly costs
Rent to the landlord plus the bills that don't change with bookings: council tax or business rates, gas, electricity, water, broadband and the TV licence.
Step 2: Work out full-occupancy income
Take your average nightly rate and multiply it by the nights in a month. Use a weighted average: our calculator blends five weekday nights and two weekend nights.
Step 3: Work out full-occupancy variable costs
These rise with every booking: platform and card fees (a percentage of income), cleaning for each turnover, and per-night consumables like toiletries and laundry.
Step 4: Divide
Divide Step 1 by Step 2 minus Step 3. The result is the share of nights you need to fill each month to break even.
What does a real rent-to-SA deal need to break even?
Here is the worked example, using the default figures from the ADVESTOR rent-to-SA calculator.
| Input | Value |
|---|---|
| Rent to landlord | £950/month |
| Nightly prices | £120 weekday and £160 weekend a night (average £131) |
| Booking and card fees | 17% |
| Cleaning | £45 per turnover, a turnover every 3 nights |
| Consumables and fixed per-night costs | £5 a night |
| Bills | £390/month |
| Result | Value |
|---|---|
| Fixed monthly costs | £1,340 |
| Breakeven occupancy | 49.4% |
| Profit at 72% occupancy | £612/month |
| Set-up cash needed | £13,400 |
| Months to recover set-up cash | 21.9 |
At 72% occupancy this flat clears £612 a month. The deal only works because 72% sits well above its 49.4% breakeven point.
How do you estimate realistic occupancy for your area?
Breakeven only means something when you compare it with the occupancy you can actually achieve. Base that number on evidence, not the optimistic figure in a deal pack.
- Study comparable listings. Find 10 to 20 short lets near the property with the same bedrooms, guest numbers and standard. Check their calendars two to three months ahead. Booked nights show demand, but some blocked dates are owners' own stays, so treat calendars as a guide rather than proof.
- Use short-let market data. Paid tools such as AirDNA and PriceLabs estimate occupancy and nightly rates for nearby listings, month by month. They are estimates too, so cross-check them against what you see on the platforms.
- Plan for the quietest month, not the average. Annual occupancy hides seasonal dips. If your quietest months fall below 49.4%, make sure the busy months more than cover them. VisitBritain's England hotel occupancy figures show how strongly demand moves through the year.
- Know who books. Contractors, hospital staff and business travellers fill weekdays; tourists and events fill weekends and holidays. A location with both is far more resilient.
- Ask local operators. Cleaners, management companies and other hosts know which streets and property types stay busy.
Then build in a buffer. A new listing has no reviews, so many operators assume lower occupancy for the first few months while it builds a track record.
What happens if occupancy or prices drop?
This table changes one thing at a time from the example above.
| Scenario | Occupancy | Monthly profit | Months to recover set-up cash |
|---|---|---|---|
| Base case (72%) | 72% | £612 | 21.9 |
| Quieter year (60%) | 60% | £287 | 46.7 |
| Tough year (50%) | 50% | £16 | Over 5 years |
| Prices 10% lower at 72% | 72% | £373 | 35.9 |
| Rent £100 higher at 72% | 72% | £512 | 26.1 |
At 50% occupancy the unit makes about £16 a month, barely above breakeven, so almost all the profit in the base case comes from the nights above breakeven. That's why a 10% price cut hurts more than most people expect.
How can you lower your breakeven occupancy?
- Negotiate the rent. Every £100 off the rent lowers breakeven by about 3.7 percentage points in this example.
- Grow direct bookings. Platform fees of 15% or more are the biggest variable cost. Repeat guests who book direct keep that margin with you.
- Set a minimum stay. Fewer turnovers means fewer cleans for each night let.
- Price weekends and peaks properly. Your average nightly rate moves breakeven more than small cost savings do.
- Check what the rent includes. Some landlords include council tax or utilities, which can turn a marginal deal into a good one.
What rules apply before you sign a rent-to-SA deal?
This is a summary, not legal advice:
- Landlord consent: you need the landlord's written permission to let the property for short stays. Their mortgage lender and insurer must allow it too.
- London's 90-night limit: in Greater London, an entire home can only be let short-term for up to 90 nights a year without planning permission.
- England registration: a national short-term let registration scheme for England had not gone live at the time of writing, so check the latest position.
- Scotland and Wales: Scotland requires a short-term let licence. Wales is introducing registration and a visitor levy.
- Guests aren't tenants: short-stay guests are not assured tenants, so the Renters' Rights Act tenancy rules that apply from 1 May 2026 don't cover them. Your agreement with the landlord still needs proper legal drafting.
Frequently Asked Questions
The Bottom Line
Breakeven occupancy shows how much bad luck a rent-to-SA deal can absorb before it starts costing you money. Work it out before you sign, aim for a wide gap above it, and use rent negotiation and direct bookings to push it lower.
