Calculator
What the RD Calculator does
RD Calculator: calculates Maturity Amount, Total Deposited and Interest Earned from Monthly Deposit, Interest Rate and Tenure. Formula: A = P x (1 + r/n)^(n x t). Example: monthly deposit 5000 ₹, interest rate 6.5 % p.a. and tenure 24 months gives maturity amount ₹1,28,425.30.
Give the RD Calculator your Monthly Deposit, Interest Rate and Tenure and it works out Maturity Amount, Total Deposited and Interest Earned. Values update as you type, so comparing options is a matter of editing one field.
Typical users are anyone weighing up a loan. Small differences in rate or term compound into large differences in what you actually pay.
We never see the amounts you enter, so there is no financial record of your visit to leak.
The field table, the method and a worked example are documented after the tool for anyone who wants to check the working.
What do the RD Calculator fields mean?
The RD Calculator uses 3 inputs. Nothing is blank on load, so you can see the shape of the answer before supplying your own figures.
| Field | What to enter | Default |
|---|---|---|
| Monthly Deposit | measured in ₹; accepts 100 to 500000 | 5000 |
| Interest Rate | measured in % p.a.; accepts 1 to 15 | 6.5 |
| Tenure | measured in months; accepts 6 to 120 | 24 |
How does the RD Calculator work?
n is how many times interest is compounded per year, so a higher n produces a larger maturity value for the same nominal rate.
Validation runs before the calculation, which is why a mistyped value shows an error rather than a plausible-looking result.
Worked example
These are the values the RD Calculator loads by default, and the result it produces from them. These are the exact values loaded when the page opens, and the answer they produce.
| Monthly Deposit | 5000 ₹ |
|---|---|
| Interest Rate | 6.5 % p.a. |
| Tenure | 24 months |
| Maturity Amount | ₹1,28,425.30 |
|---|---|
| Total Deposited | ₹1,20,000.00 |
| Interest Earned | ₹8,425.30 |

How to use it
- Set Monthly Deposit in ₹ (100 to 500000).
- Put Interest Rate in % p.a. (1 to 15).
- Key in Tenure in months (6 to 120).
- Results update continuously rather than on submit.
- Check Maturity Amount, Total Deposited and Interest Earned on the right.
- Print gives a tidy version without the navigation, which is handy for attaching to a file.
What this tool does not do
- Fees, taxes and eligibility rules vary by product and are not included unless there is a field for them.
- Lender rounding rules differ, so the final figure on your statement may differ by a small amount.
- Comparisons across tools can differ where each uses a slightly different definition.
- The tool trusts your numbers completely, so a mis-keyed digit propagates straight through.
Frequently asked questions
Enter Monthly Deposit in ₹, Interest Rate in % p.a. and Tenure in months. Every input names its unit, and every output does too, which removes the usual source of error.
Monthly Deposit accepts 100 to 500000 ₹. Go outside it and you get an error against that specific field instead of a misleading number.
With the values loaded when the page opens, maturity amount comes out as ₹1,28,425.30. Overwrite any of the starting values and the result follows.
No. Your browser is doing the computing, so we could not see the values even if we wanted to.
No payment and no login. Advertising covers the running costs.
It is precise to the method and honest about its scope: no calculator can know your eligibility, and eligibility is what usually moves the final number.
