What this calculation tells you
This is the reverse of the EMI calculation. Instead of starting with a principal, you enter a monthly instalment and ask which principal would produce that payment at the stated rate and tenure.
The output is a mathematical principal, not an approval amount or assessment of personal affordability. Income, existing commitments, eligibility, emergencies and fees are not considered. Use it to understand the link between payment, rate and duration, then check an actual lender’s terms.
The method, explained
Principal = monthly payment × [1 − (1 + r)^(−n)] ÷ r r = annual rate ÷ 1,200
The inputs use the units printed beside each field. Values shown in result cards are rounded for readability; the calculator keeps more precision while applying the formula.
A worked example
Monthly payment to model: ₹15,000.00 · Annual loan interest rate: 9 % · Loan tenure: 60 months.
Loan amount for this EMI: ₹7,22,600.60
This example uses the inputs above. Your result changes when you change them.
Assumptions & limitations
- The rate is fixed and payments are monthly at period-end.
- No credit assessment, income test, fees or insurance is included.
- The amount is not a lending offer or a recommendation about how much to borrow.
