Rental yield calculator

Enter the price and the monthly rent, then the service charge and the share of rent that letting and upkeep take. The gross yield is the headline; the net yield is the one to compare with other investments.

Your figures

Home pages fill this in with the ONS average for the area and bedroom count.

Leasehold apartments only; a house is usually nil.

Agent fees, repairs, insurance and empty weeks. 10% to 20% is usual.

How yield is worked out

A year of rent over the price, then the same after the costs of being a landlord.

Gross yield
Annual rent ÷ price. £1,250 a month on a £300,000 home is £15,000 a year, a 5.0% gross yield. It ignores every cost, which is why it flatters.
Net yield
The same after the service charge and ground rent, agent fees, repairs, insurance and the weeks the home stands empty. With a 15% allowance and no service charge the example falls to 4.3%; a £2,400 service charge takes it to about 3.5%.
Not in the figure
Mortgage interest, income tax (and the fact that interest is no longer fully deductible for individual landlords), the second-home stamp duty surcharge and any change in the home’s value. New builds tend to let quickly and for a premium, but the premium fades as the home ages.

Questions people ask

What is a good rental yield?

Gross yields of 5% to 7% are typical in northern cities and 3% to 4% in London and the South East, where prices are higher relative to rents. Compare the net figure with what the same money would earn elsewhere, and remember it is before tax and mortgage interest.

Is a new build a good buy-to-let?

It lets fast, needs little maintenance in the early years and the warranty covers structural defects, but you pay a new-build premium and on an apartment the service charge comes straight off the yield. Enter the real service charge from the listing rather than leaving it at zero.

Where does the rent come from?

From a home page the rent is the ONS average for that bedroom count in the area for the latest month published. Ask a local agent for the figure a new build would achieve; it is often above the average.
