Mortgage insurance is estimated at 0.6% of the balance a year and only applies above 80% LTV. Your lender will quote its own figure.

A mortgage payment is rarely just principal and interest. Property tax, home insurance and, below twenty percent equity, mortgage insurance are all added. This calculates the full monthly figure and the total interest across the term.

How to use the Mortgage Calculator

  1. Enter price and deposit. The difference is what you borrow, and it sets your loan-to-value.
  2. Set rate and term. Use the quoted annual rate. Thirty years is the common default; try twenty-five to see the difference.
  3. Add tax and insurance. Annual figures. Both are divided into the monthly cost, as a lender would.

About mortgage payments

Most mortgage calculators answer a narrower question than the one buyers are actually asking. They compute principal and interest, which is what the lender charges, and stop there — but the money that leaves your account each month also covers property tax, buildings insurance and, if your deposit is under twenty percent, mortgage insurance that protects the lender rather than you. On a typical purchase those additions can be a fifth of the monthly cost, which is the difference between a house being affordable and not. Loan-to-value is the number to watch when shopping. It determines whether mortgage insurance applies at all, and it moves you between lender pricing tiers, so a slightly larger deposit can be worth far more than its face value if it pushes you under a threshold. The other figure worth staring at is total interest. Over thirty years it frequently exceeds the amount borrowed, which is why shortening the term or overpaying early has such disproportionate effect: money repaid in the first years removes interest that would otherwise compound for decades.

Frequently asked questions

What is loan-to-value and why does it matter?
The share of the property price you are borrowing. Below 80% you usually avoid mortgage insurance and access better rates; above 95% the choice of lender narrows sharply.
What is PMI and can I avoid it?
Private mortgage insurance protects the lender, not you, and is normally required above 80% loan-to-value. It typically costs 0.5% to 1% of the balance a year and usually falls away once you reach 20% equity.
Should I take 25 years instead of 30?
The monthly payment rises but total interest falls, often by a very large amount. Compare the total interest figure across both, not the monthly one, then decide what you can genuinely sustain.
Is this the exact figure my lender will quote?
No. It excludes closing costs, service charges, HOA fees and any escrow arrangement, and mortgage insurance is estimated. Treat it as a close approximation for comparing options.
