Property Loan EMI & Mortgage Calculator
Two calculators in one: simple loan EMI, or a full mortgage with down payment — free, private, all in your browser.
Loan EMI
One Payment Question, Two Common Versions
"What will my monthly payment be?" gets asked in two slightly different forms depending on the situation: a straightforward loan against a fixed principal, or a home purchase where a down payment reduces how much is actually financed. Rather than sending one group of visitors to a generic loan calculator and another to a separate mortgage tool, this page handles both from the same interface, switching the underlying math based on which tab is active.
Running Either Calculation
- Choose your mode: Loan EMI for a direct loan amount, or Mortgage for a property purchase with a down payment.
- Enter the relevant figures: Loan EMI needs amount, rate, and term; Mortgage additionally needs property price and down payment.
- Tap Calculate: See monthly payment, total interest, and total payable instantly.
- Copy or reset: Save the breakdown, or reset to test a different scenario.
The Formula Underneath
Both modes run the same standard EMI (Equated Monthly Installment) formula — the same one banks and mortgage lenders use — which converts a principal, a monthly interest rate, and a total number of payments into one fixed monthly figure. Loan EMI mode applies this directly to the loan amount you enter. Mortgage mode does one extra step first: it subtracts your down payment from the property price to find the actual amount being financed, expresses the down payment as a percentage of the property price, and then runs the same EMI formula against that smaller loan amount.
Worked Example: Loan EMI on PKR 5,000,000
A loan of PKR 5,000,000 at 12% annual interest over 20 years produces a monthly EMI of PKR 55,054. Across 240 monthly payments, total amount payable comes to PKR 13,213,034 — meaning total interest paid over the full term is PKR 8,213,034, more than the original principal itself. That gap between principal and total interest is exactly why the calculator shows both the monthly figure and the full-term total: a payment that looks affordable monthly can still represent a very large total cost once the full term is accounted for.
Worked Example: Mortgage on an 8,000,000 Property
Now take a property priced at PKR 8,000,000 with a PKR 1,600,000 down payment (20%), the same 12% rate, and the same 20-year term. The actual loan amount financed is PKR 6,400,000 — the property price minus the down payment. That produces a monthly payment of PKR 70,470 and total interest of PKR 10,512,683 over the full term. Compare this to a hypothetical 10% down payment on the same property: the financed amount rises, and so does both the monthly payment and total interest — which is exactly the trade-off Mortgage mode is built to show clearly.
Who Uses Each Mode
Someone taking a personal or business loan — not tied to a property purchase — uses Loan EMI directly to see what a lender's offer actually costs monthly and in total before signing anything. A home buyer comparing two or three properties uses Mortgage mode to see how a bigger down payment lowers the monthly commitment, or to check whether a property realistically fits their budget once actual financing terms replace a rough guess. Both modes are also used simply to sanity-check a number a bank or lender has already quoted.
What Actually Moves the Number
A larger down payment reduces both the financed loan amount and the total interest paid — even a modest increase in down payment can meaningfully lower the monthly figure, since it shrinks the base the interest is calculated against for the entire term. Comparing offers on total payable rather than just the monthly figure matters too: a longer term often looks more affordable per month while quietly costing significantly more in total interest paid across the loan's full life.
A Limitation Worth Knowing
This calculator assumes a fixed interest rate for the entire term — it doesn't model a variable or step-up rate structure some lenders offer, where the rate changes partway through the loan. For a variable-rate offer, run the calculation using the initial rate to get a starting-point estimate, but treat any total-interest figure as approximate since the real total will shift if the rate changes later.

Frequently Asked Questions
Why is the same EMI formula used for both a plain loan and a mortgage?
Because a mortgage is functionally a loan against a smaller principal (the property price minus the down payment); the underlying monthly payment math is identical once that principal is determined.
How much does a 20% down payment reduce the monthly mortgage payment compared to 10%?
It reduces the financed amount, so the exact reduction depends on the property price, rate, and term — enter both scenarios in Mortgage mode to compare the specific numbers directly.
Does a longer loan term always mean paying more total interest?
Generally yes, since interest accrues over more payments even though each individual payment is smaller — always check the total payable figure, not just the monthly amount, when comparing terms.
Can this calculator handle a variable or step-up interest rate?
No, it assumes a fixed rate for the full term; for a variable-rate loan, use the starting rate for an initial estimate and recalculate if the rate changes.
Is the EMI formula used here the same one banks actually use?
Yes, it's the standard Equated Monthly Installment formula used across the lending industry for fixed-rate amortizing loans.
Does this show total interest paid?
Yes, both calculators show total interest paid over the full loan term alongside the monthly payment and total amount payable.
Can I copy or save my result?
Yes, use the Copy Result button on either calculator to copy the full breakdown to your clipboard.
