What the SWP Calculator does
SWP Calculator: calculates Total Withdrawn, Final Corpus and Interest Earned from Total Investment (Corpus), Monthly Withdrawal and Expected Return. Example: total investment (corpus) 1000000 ₹, monthly withdrawal 10000 ₹ and expected return 10 % p.a. gives total withdrawn ₹12,00,000.00.
The inputs are Total Investment (Corpus), Monthly Withdrawal, Expected Return and Withdrawal Tenure; the output is Total Withdrawn, Final Corpus and Interest Earned. Adjust anything and the figures re-derive on the spot.
Most people who open the SWP Calculator are savers modelling a goal. Getting the arithmetic right before you sign is cheaper than discovering it afterwards.
Because it is all local, the tool is as fast as your device and as private as your own notes.
The field reference, the method and a worked example using the default inputs follow the tool itself.
What do the SWP Calculator fields mean?
The SWP Calculator uses 4 inputs. The page opens in a usable state: real values in, real answer out, ready to edit.
| Field | What to enter | Default |
|---|---|---|
| Total Investment (Corpus) | measured in ₹; accepts 10000 to 100000000 | 1000000 |
| Monthly Withdrawal | measured in ₹; accepts 500 to 5000000 | 10000 |
| Expected Return | measured in % p.a.; accepts 0 to 30 | 10 |
| Withdrawal Tenure | measured in years; accepts 1 to 40 | 10 |
How does the SWP Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
Bad input produces a message, not a silently incorrect figure.
Worked example
These are the values the SWP Calculator loads by default, and the result it produces from them. Below is the same computation the tool performs on load, step by step.
| Total Investment (Corpus) | 1000000 ₹ |
|---|---|
| Monthly Withdrawal | 10000 ₹ |
| Expected Return | 10 % p.a. |
| Withdrawal Tenure | 10 years |
| Total Withdrawn | ₹12,00,000.00 |
|---|---|
| Final Corpus | ₹6,58,591.70 |
| Interest Earned | ₹8,58,591.70 |
| Corpus Lasts (years) | 10.00 |
| Status | Corpus lasts full tenure |

How to use it
- Key in Total Investment (Corpus) in ₹ (10000 to 100000000).
- Fill in Monthly Withdrawal in ₹ (500 to 5000000).
- Type Expected Return in % p.a. (0 to 30).
- Enter Withdrawal Tenure in years (1 to 40).
- No confirmation step: what you type is what gets calculated.
- Read Total Withdrawn, Final Corpus, Interest Earned, Corpus Lasts (years) and Status in the results panel.
- Copy Link when you want to return to this exact configuration; Print when someone needs it on paper.
What this tool does not do
- Rates are treated as fixed for the whole term; a floating rate will change the outcome.
- Fees, processing charges and taxes are not included unless there is a field for them.
- Treat it as a fast first pass, not as the final word on a decision that matters.
- A plausible-looking answer from the wrong input is still the wrong answer: verify the fields first.
Frequently asked questions
Enter Total Investment (Corpus) in ₹, Monthly Withdrawal in ₹, Expected Return in % p.a. and Withdrawal Tenure in years. Each field states its unit next to the input, and outputs are labelled the same way.
Total Investment (Corpus) accepts 10000 to 100000000 ₹. The range is enforced before the calculation runs, so a bad entry never reaches the formula.
With the values loaded when the page opens, total withdrawn comes out as ₹12,00,000.00. Adjust any field to see how much the answer depends on it.
No. Disconnect from the internet and it still works; that is the simplest proof there is no server call.
No charge. Everything on the page is available without signing in.
The arithmetic will match any correct implementation. What it cannot include is the processing fee, the insurance bundled into the offer, or the rate band you actually qualify for.
