Rental Yield Calculator

Quickly estimate gross yield, net yield, and rental cashflow for a buy-to-let property. This calculator factors in rent, occupancy, management fees, running costs, and mortgage interest to help landlords assess deal performance and compare scenarios before buying or refinancing.

Rental Yield Calculator

Estimate gross yield, net yield, and yearly cashflow in one place.

Property price (£) What you paid (or expect to pay) for the property. Monthly rent (£) Expected rent per month. Average occupancy (%) Use 100% if fully let all year. Use 92–98% if you expect voids. Letting/management fee (%) Percentage of collected rent (set to 0 if self-managing). Yearly running costs (£) Repairs, insurance, certificates, service charge, ground rent, etc. Mortgage interest per month (£) Optional. If you add this, we’ll show cashflow after interest.

Gross yield — Annual rent (before costs) ÷ property price.

Net yield — After fees and running costs (before mortgage interest).

Net cashflow per year — After fees and running costs (before mortgage interest).

Cashflow after interest (per year) — Optional: includes the mortgage interest field.

Cashflow after interest (per month) — Helps you sanity-check month-to-month affordability.

Collected rent per year — Monthly rent × occupancy.
