What a mortgage repayment really means for your budget
A repayment figure on its own doesn't tell you much — what matters is how it sits against your actual after-tax income, and, if your income is irregular, how many months of repayments you could cover from savings if work dried up.
This calculator connects your mortgage repayment to our income tax engine so you can see both the repayment as a share of your take-home pay and a buffer-months figure for variable contractor income.
What this calculator shows
- Your estimated mortgage repayment for a given loan amount, rate and term
- That repayment expressed as a percentage of your after-tax take-home pay
- A buffer-months figure based on your savings and the repayment amount
- How extra repayments change the loan term and total interest
