What the Personal Loan Calculator does
Personal Loan Calculator: calculates EMI, Principal and Interest from Loan Amount, Interest Rate and Tenure. Formula: EMI = P x r x (1 + r)^n / ((1 + r)^n - 1). Example: loan amount 300000 ₹, interest rate 16 % p.a. and tenure 3 years gives EMI ₹10,547.11.
From Loan Amount, Interest Rate and Tenure, this tool derives EMI, Principal and Interest. Results refresh instantly, so trying variations costs nothing but a moment.
Seeing the total cost, not just the monthly figure, is what usually changes decisions. That is usually what brings someone checking a lender quote here.
There is no back end here. The calculation runs where you are sitting, not on a server somewhere.
The method, a field-by-field reference and a worked example built from the defaults are all on this page.
What do the Personal Loan Calculator fields mean?
The Personal Loan Calculator uses 3 inputs. Every field is populated on load; treat those numbers as a template rather than a suggestion.
| Field | What to enter | Default |
|---|---|---|
| Loan Amount | measured in ₹; accepts 25000 to 4000000 | 300000 |
| Interest Rate | measured in % p.a.; accepts 0.1 to 30 | 16 |
| Tenure | measured in years; accepts 1 to 40 | 3 |
How does the Personal Loan Calculator work?
P is the principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments.
Validation is deliberately strict: silently coercing a bad value is how wrong numbers get trusted.
Worked example
These are the values the Personal Loan Calculator loads by default, and the result it produces from them. This walkthrough uses the starting values, which means you can follow along without typing anything.
| Loan Amount | 300000 ₹ |
|---|---|
| Interest Rate | 16 % p.a. |
| Tenure | 3 years |
| EMI | ₹10,547.11 |
|---|---|
| Principal | ₹3,00,000.00 |
| Interest | ₹79,695.96 |
| Total Payable | ₹3,79,695.96 |
What makes personal loans different
Personal loans are the most expensive mainstream borrowing after credit cards, precisely because there is nothing for the lender to repossess. The rate you are offered depends heavily on your credit score and income stability.
| Typical rate | 10.5% to 24% p.a. |
|---|---|
| Typical tenure | 1 to 5 years |
| Typical amount | ₹50,000 to ₹40,00,000 typically |
| Security | Unsecured. No collateral, which is why rates are several times a home loan. |
Rate and tenure ranges are indicative of the market and are not an offer or a quote. The rate you are offered depends on your credit profile, income and the individual lender.
Points that change the real cost
- Rate dispersion is huge
- The gap between the best and worst offers on the same product can be 13 percentage points. Unlike a home loan, shopping around here is worth serious money.
- Credit score drives the band
- A score above 750 typically accesses the lowest published rates. Below 650, many lenders decline outright rather than price for the risk.
- Processing fees
- Usually 1% to 3%, frequently deducted from the disbursed amount. You borrow ₹5,00,000 and receive ₹4,85,000 while repaying on the full figure, which raises the effective rate above the quoted one.
- Prepayment penalties
- Common on personal loans, typically 2% to 5% of the outstanding principal, sometimes with a lock-in for the first 6 to 12 months.
- No tax deduction
- Interest on a personal loan is not deductible in India unless the funds are demonstrably used for business, house construction or education.

How to use it
- Fill in Loan Amount in ₹ (25000 to 4000000).
- Type Interest Rate in % p.a. (0.1 to 30).
- Enter Tenure in years (1 to 40).
- Watch the results panel as you type: it recalculates on every keystroke.
- The panel reports EMI, Principal, Interest and Total Payable.
- Share the link rather than a screenshot. It carries the values with it.
What this tool does not do
- Fees, processing charges and taxes are not included unless there is a field for them.
- Lender rounding conventions differ, so your statement may vary by small amounts.
- It cannot detect a typo that happens to fall inside the valid range.
- Confirm the units before you act on the output. The arithmetic is only as sound as what went in.
Frequently asked questions

Loan Amount accepts 25000 to 4000000 ₹. If a value falls outside, the tool says which field is at fault instead of guessing.
With the values loaded when the page opens, EMI comes out as ₹10,547.11. Change a value and the number is recomputed on the spot.
It never leaves the tab. The page does the work itself rather than asking a server to.
It is free to use, with no premium tier holding back the useful parts.
The calculation is precise; the assumptions are yours. Change one input and you will see how sensitive the result is, which is usually the more useful insight.
