How This Calculator Works

SA income is modelled from nightly rate and occupancy rather than a fixed monthly rent: Annual Revenue = Nightly Rate × Occupancy % × 365. From that monthly figure, the calculator deducts platform fees (Airbnb/Booking.com), an all-in management fee, and cleaning costs (per stay × average stays per month) to reach gross monthly income, then subtracts your mortgage payment for net cashflow. Because SA income swings with occupancy, the sensitivity table below re-runs the same costs across a 40–90% occupancy range so you can see the downside case, not just your target scenario.

Worked example (the default figures pre-filled above): £120/night at 65% occupancy — annual revenue £28,470, or £2,372.50/month. Costs: 3% platform fee (£71.18) + 20% management (£474.50) + cleaning at £60 × 8 stays/month (£480) = £1,025.68/month. Gross monthly: £1,346.83. After an £800 mortgage payment: net monthly cashflow £546.83.

SA / Airbnb FAQs

PropertyBrain Editorial Team — figures reflect typical UK SA market ranges, not guaranteed outcomes. Last verified: July 2026. Always check local Article 4 / planning restrictions before committing to an SA strategy. This is not financial advice.
Is SA more profitable than standard buy-to-let?

SA typically generates 1.5–3× more monthly income than BTL at good occupancy. A property producing £800/month on AST might yield £1,800–£2,500/month as SA. However, SA carries higher costs (platform fees, management, cleaning) and more operational complexity. Article 4 Directions in some areas restrict SA — always check planning before committing.

What occupancy should I assume for Airbnb?

A realistic UK baseline is 60–70% for well-positioned city properties. Prime locations (London, Edinburgh, Bath) can reach 75–85%. Seasonal or rural properties may be 40–55%. Use 60–65% for conservative cashflow modelling.

What are typical SA management costs?

Full-service SA management runs 20–30% of revenue (platform + management + cleaning combined). Airbnb alone charges ~3% host fee; Booking.com ~15%. If you self-manage, your main cost is cleaning (£50–£100/stay). Our model lets you configure each cost separately.
