Learn more about privacyA mortgage payment is rarely just the mortgage. Property tax and insurance often add a fifth on top, and a budget built on the loan payment alone is a budget that breaks in the first year.
What Mortgage Calculator does
Calculates the monthly payment on a mortgage, and adds property tax and home insurance so the figure resembles what actually leaves your account.
Deposit is deducted from the price to give the amount borrowed, so you can see immediately how much a larger deposit changes both the payment and the total interest.
What goes into the monthly figure
| Principal and interest | From the amount borrowed, rate and term |
|---|---|
| Property tax | Entered annually, divided across the year |
| Home insurance | Entered annually, divided across the year |
| Not included | Service charges, ground rent, mortgage insurance, maintenance |
| Term range | 1–50 years |
| Rate range | 0–30% a year |
| Common lender comfort limit | Total debt payments around 36% of income |
Detailed steps
- Enter the price and your deposit.
- Enter the rate and term.
- Put in real property tax and insurance figures for the specific area — national averages are close to useless here, since tax varies enormously between districts.
- Compare the total against what you actually have spare each month.
Worth knowing
Whatever this produces, add a maintenance allowance before deciding what you can afford. A common planning figure is around 1% of the property value a year, and it is the cost that catches first-time buyers — a boiler does not care what your amortisation schedule says.
Frequently Asked Questions
What is not included in this figure?
Service charges, ground rent, mortgage insurance where a small deposit requires it, utilities and maintenance. On some properties those add more than the tax and insurance combined, so treat the result as the floor rather than the total.
How much difference does the deposit make?
Two ways. It reduces the amount borrowed, which lowers the payment proportionally, and above certain thresholds it can unlock a better rate or remove mortgage insurance. Try a few deposit figures and watch both the payment and the total interest.
Should I take the longest term I can?
It lowers the monthly payment and raises the total substantially, because interest compounds on the balance you still owe. Whether that trade is right depends on your income stability, not on the arithmetic — the calculator shows the cost, it cannot weigh the risk.
Is this accurate enough to budget on?
It is an estimate for comparing scenarios, not an offer. Your lender’s figure will differ slightly, and local tax and insurance vary. Use it to narrow the range, then work from the actual illustration a lender gives you.
