How to calculate Private Residence Relief amount

Hi, When using the HMRC CGT calculator, it expects you to provide the actual value of PRR. So I'm trying to understand how to calculate this. Please can you check the example below and let me know if I am doing this correctly? A non-resident selling UK residential property owned since 2010 only has to pay CGT on the capital gain since 6 April 2015. They lived in the property for 5 years (60 months) before April 2015 In the period since April 2015 they qualify for 4 years (48 months) Private Residence Relief. If they sell the property on 5 April 2024 that would be 168 months since they bought the property and 108 months since 6 April 2015 To calculate the value of the PRR you have to multiply the Gain x (period of occupation / total period of ownership) So for a for a non-resident who is only liable for CGT on the gain since April 2015 can they apply the above calculation only for the period since 2015: Gain (since 6 April 2015) X 48 months occupation (since 6 April 2025) / 108 months ownership (since 6 April 2016) Or do they have to work out the Private Residence portion across the whole ownership period ie Gain (since 6 April 2015) X (93 months total occupation / 168 months total ownership) And would there be any difference if you use the straight-line apportionment method vs the rebasing method? Thanks
