Loan Calculator – Free, Fast & Accurate (2026)
Estimate monthly loan payments from principal, interest rate, and tenure.
Last updated:
Quick answer
A loan calculator estimates periodic payments on an amortizing loan from amount financed, interest rate, and number of payment periods.
It is structurally the same family as EMI and mortgage payment tools: solve for a level payment that retires the balance over time.
Check whether your lender uses add-on interest, balloon payments, or fees that a simple amortization model does not include.

Formula
Monthly Payment = [P x r x (1+r)^n] / [(1+r)^n - 1]
Explanation
Loan Calculator computes results using the formula Monthly Payment = [P x r x (1+r)^n] / [(1+r)^n - 1] from your input values: principal, interest rate (%), and tenure (months). Entering each field returns a numerical answer based on that exact equation, so the page is a faster, less error-prone alternative to running the math by hand.
It is built for budget planning and monthly cash-flow checks, loan comparisons before committing to repayments, and investment projections for short-term and long-term goals. People typically open this calculator when they need a quick, repeatable answer they can check in seconds—students confirming a homework number, professionals validating a real-world figure, or anyone running a what-if scenario before making a decision.
Read the result alongside the formula on this page so each input's effect is transparent, then re-run with adjusted values to see how the answer changes. If anything looks off, double-check unit consistency in your inputs—mixing percent values with decimals or months with years is the most common source of an unexpected result.
How to Use
- Enter or choose Principal, Interest Rate (%), and Tenure (months) as indicated.
- Use the units shown under each field (for example kg, m, cm, years).
- Click Calculate to run the Monthly Payment = [P x r x (1+r)^n] / [(1+r)^n - 1] formula.
- Read the result and compare with alternate values if you want scenario-based planning.
Example
Sample inputs: Principal = 250000, Interest Rate (%) = 9.5, Tenure (months) = 60
Calculated result: 5250.4653
You can replace these values with your own numbers to calculate a real-world result instantly.
