About Landlord Sums

Landlord Sums is a set of free calculators for people who let property in the UK. Each one answers a question landlords ask before a decision: what will this cost, what will I keep, and when can I act.

Where the figures come from

Tax rates, thresholds and rules come from GOV.UK and HMRC guidance, linked on each page. Every calculator shows the date it was last checked. When the rules change, the calculators change too.

What it isn't

The calculators give estimates to help you plan. They aren't financial, tax or legal advice. For decisions like moving property into a company, speak to a qualified accountant or solicitor.
