About Private Residence Relief Calculator UK

Private Residence Relief Calculator UK helps you work through the main numbers for this topic quickly with a simple input flow and an instant result.

Use the calculator result as a practical starting point, then review the explanation and assumptions on the page if you want more context.

How the relief fraction works

The calculator counts days in a single continuous only-or-main-residence interval and the final nine months of ownership without double-counting overlap. It applies that fraction to your gain after allowable costs. GBP 73,000 multiplied by 640 qualifying days over 730 ownership days gives GBP 64,000 illustrative relief.

HMRC rules can also recognise qualifying absences and special circumstances, but these require facts this calculator does not collect. The remaining gain is before any annual exemption or CGT rate calculation.
