Mortgage Calculator
Estimate monthly mortgage payments from loan amount, interest rate, and term.
Results are estimates. Banks may use different day-count conventions, fees, or variable rates.
Guide: Mortgage Calculator
Use this free mortgage calculator to estimate your monthly home-loan payment, total interest over the life of the loan, and how much you will repay in all. Whether you are comparing bank offers or stress-testing a budget, entering principal, annual rate, and term gives you a clear baseline in seconds. It is especially useful before you visit a lender, so you can ask informed questions about processing fees, floating vs fixed rates, and how optional insurance would change your cash flow.
How our mortgage payment calculator works
The tool applies a standard fixed-rate amortizing loan formula. Your payment stays constant each month while the split between principal and interest shifts over time: early payments are mostly interest; later payments pay down more principal.
This page is built for quick planning. Your bank may quote an effective APR, include insurance, or use a different day-count method, so treat the output as an estimate rather than a binding quote.
If you are comparing two offers with the same nominal rate but different fees, remember that upfront costs change your effective cost of borrowing even when the monthly payment looks identical.
What to enter for realistic PKR results
Principal should reflect the amount you actually borrow after your down payment. Rate should match the annual percentage the lender quotes for the same compounding basis (usually monthly for consumer mortgages). Term is the full repayment horizon in years.
If you expect to prepay or refinance, rerun the calculator with a shorter remaining term to see how much interest you could save.
For affordability, try entering a payment cap as a reverse goal: adjust principal or term until the installment fits roughly one-third of your stable net income rule of thumb, then validate with a loan officer.
When a mortgage calculator helps most
Home buyers use mortgage calculators to compare offers, decide how much house fits a payment cap, and understand the long-term cost of stretching the term.
Pair this tool with your own research on fees, registration costs, and insurance so your budget reflects the full picture.
Investors analyzing rental yield can also use it to isolate financing cost from gross rent, though vacancy and maintenance belong in a separate spreadsheet.
Fixed rate vs floating in simple terms
A fixed rate locks your nominal rate for the quoted period, which stabilizes payment planning. A floating (variable) rate can start lower but changes with market benchmarks, so your payment may rise or fall after reset dates.
This calculator assumes the rate you enter stays fixed for the whole term. For floating loans, run best-case, base-case, and stress-case rates to see how sensitive your budget is to higher installments.
