Buy-to-let Property Profit (and tax) Calculator

You can use this calculator to estimate the profit (and yield/ROI from your investment) that you'll achieve from purchasing a buy-to-let property. We also have a remortgage profit calculator if you're refinancing an existing buy-to-let property. Or fill in your original figures for a past property purchase to see how it's performing (note that the total investment calculated will include 3% second home stamp duty so may be incorrect if you purchased the property before that came into effect.

This calculator also provides estimated after tax profit figures and shows how your income will be affected as the mortgage interest relief rules (Section 24) change from 2016 to 2020.
