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.
Buying a home in Pakistan almost always means borrowing part of the price from a bank or housing finance company, and the single most important number in that decision is your monthly installment. This mortgage calculator turns three simple inputs — the loan amount, the annual interest rate, and the repayment term — into a clear monthly payment, a total interest figure, and the full amount you will repay over the life of the loan.
Rather than waiting for a loan officer to run the numbers for you, you can test multiple scenarios in seconds: a 15-year term against a 20-year term, a 12% rate against a 14% rate, or a smaller principal after a bigger down payment. That flexibility is exactly what you need when you are comparing offers from HBL, Meezan Bank, Bank Alfalah, or any other housing finance provider in Pakistan, because the headline rate alone never tells the whole story.
This page explains how the underlying math works, walks through worked PKR examples, and flags the mistakes that trip up first-time home buyers most often, so that by the time you sit down with a bank you already understand exactly what you are signing up for.

How the mortgage calculator works
The calculator uses the standard fixed-rate amortizing loan formula that almost every housing finance product in Pakistan is built on. You borrow a principal amount, the bank charges interest on the outstanding balance at a fixed monthly rate, and you repay a level installment every month until the balance reaches zero.
Because the payment amount stays constant, the mix inside each installment changes over time. In the first few years, most of your payment is interest, since the balance is still large. In the final years, most of the same payment goes toward principal, because the balance has shrunk. This pattern is called amortization, and it explains why paying off a home loan early saves disproportionately more interest than most borrowers expect.
The tool assumes monthly compounding on a fixed nominal annual rate, which matches how most Pakistani banks quote housing finance. If your bank uses a floating rate linked to KIBOR, treat the calculator's output as a snapshot for the current rate rather than a guaranteed lifetime figure.
How to use this calculator step by step
Start by entering the principal — this should be the amount you are actually borrowing after your down payment, not the full property price. Most Pakistani lenders require a down payment of 15% to 30% depending on the product and your income profile, so the loan amount is usually well below the market value of the home.
Next, enter the annual interest rate exactly as quoted by your bank, and the term in years. Click calculate and the tool instantly shows your monthly installment, total interest paid over the full term, and the grand total you will repay. Run the numbers again with a shorter term to see how much interest a faster payoff schedule could save you, or with a smaller principal to see how a bigger down payment changes the picture.
The formula explained
The monthly payment formula is EMI = [P x R x (1+R)^N] / [(1+R)^N - 1], where P is the principal, R is the monthly interest rate (the annual rate divided by 12), and N is the total number of monthly payments (the term in years multiplied by 12).
This formula solves for the single level payment that fully amortizes the loan — meaning the last payment brings the balance to exactly zero — given the rate and number of periods you specify. It is the same formula banks use internally, so a correctly entered set of inputs should match your bank's quoted installment very closely, aside from rounding and any fees the bank adds separately.
Worked PKR example
Suppose you want to buy a home worth PKR 12,000,000. You make a 20% down payment of PKR 2,400,000, leaving a loan amount of PKR 9,600,000. Your bank offers a 15-year housing finance product at 14% per year.
Plugging those numbers in, the monthly installment works out to roughly PKR 127,600. Over 15 years (180 months) you would pay about PKR 22,970,000 in total, meaning total interest of around PKR 13,370,000 — more than the original loan amount itself. This is normal for long-term housing finance in a high-rate environment, and it is exactly why comparing even a one or two percentage point difference in rate across lenders is worth the effort.
If you shortened the term to 10 years instead, the monthly installment would rise to roughly PKR 148,900, but total interest would fall to around PKR 8,270,000 — a saving of more than PKR 5,000,000 simply by choosing a faster payoff schedule.
Tips and common mistakes to avoid
Do not enter the full property price as your principal; use the amount you will actually borrow after subtracting your down payment. Confirm whether your quoted rate is fixed for the full term or floating and linked to KIBOR, since a floating rate can rise or fall after a reset period and your real installment may differ from this static projection.
Watch out for processing fees, insurance premiums, and legal or registration charges that many banks add on top of the loan — these are not part of the amortization formula but still affect your total cost of homeownership. Finally, if you are choosing between two offers with similar monthly payments but different fee structures, compare the total cash outflow over the full term rather than just the advertised installment.
When to use related calculators
If you are also financing a car alongside the home purchase, switch to the Auto Loan Calculator so the two installments do not overlap in a way that strains your monthly budget. For a general-purpose installment loan such as a personal loan for the down payment itself, the Loan Calculator uses the identical EMI engine.
Once you know your target installment, the Payment Calculator can help you work backward from an affordable monthly figure to the maximum principal you should borrow, and the Inflation Calculator is useful for understanding how the real value of a fixed monthly payment shrinks over a 15- or 20-year mortgage term.
