What your mortgage payment really means for your take-home pay
A monthly mortgage repayment figure on its own doesn't tell you much without knowing how it sits against what you actually take home — and for contractors, take-home pay can vary month to month and route to route (umbrella, inside IR35, outside IR35) in a way permanent salaries don't.
What this calculator shows
- Your estimated monthly mortgage repayment from the loan amount, interest rate and term you enter
- That repayment expressed as a percentage of your actual net take-home pay, computed using our contractor and salary take-home engines rather than a rough gross-income estimate
- A stress-test view showing what happens to that percentage if interest rates rise, useful given how much contractor income itself can vary between inside-IR35, outside-IR35 and umbrella routes
- A side-by-side view if you're comparing affordability under different income routes, such as staying inside IR35 versus a prospective outside-IR35 contract
