What is a SWP Calculator?
A Systematic Withdrawal Plan (SWP) Calculator is a free online financial tool that helps you estimate how long your mutual fund corpus will last or what your remaining balance will be after regular withdrawals. It works by simulating monthly compounding on your invested amount and deducting a fixed withdrawal each month.
Unlike SIPs where you invest monthly, SWPs are about withdrawing a fixed sum from your investment while the remaining corpus continues to grow.
The Business Day SWP Calculator shows your total amount withdrawn, ending balance, and net profit or loss, giving you a clear view of your post-retirement or regular-income planning.
How can a SWP Calculator help you?
A SWP calculator helps investors plan consistent income and financial stability during retirement or other phases where steady cash flow is needed.
Here’s how it helps:
- 📊 Visual clarity: See how your corpus changes every year based on returns and withdrawals.
- 💡 Smart income planning: Choose the ideal withdrawal amount that lasts the entire investment period.
- ⏳ Avoid depletion: Know when your funds may run out if withdrawals exceed returns.
- 💰 Compare scenarios: Test different withdrawal amounts or durations instantly.
- 🧾 Tax-efficient planning: Use insights to select funds that minimize capital-gains impact.
It’s the perfect planning companion for retirees, freelancers, or anyone seeking steady periodic income from mutual funds.
How does an SWP Calculator work?
The calculator uses the concept of monthly compounding and fixed withdrawals.
🧮 Formula:
Where:
- P = Total investment amount
- W = Monthly withdrawal amount
- r = Monthly rate of return (annual rate ÷ 12 ÷ 100)
- n = Total number of months
This formula compounds your investment each month and subtracts the fixed withdrawal after growth.
Example
| Parameter | Value |
|---|---|
| Total Investment (P) | ₹20,00,000 |
| Monthly Withdrawal (W) | ₹25,000 |
| Expected Return | 10% per annum (0.833% per month) |
| Duration | 10 years (120 months) |

| Calculation Type | Amount |
|---|---|
| Total Withdrawn | ₹30,00,000 |
| Ending Corpus | ₹12,84,000 |
| Net Growth (Interest) | ₹-7,16,000 (partial depletion over time) |
✅ This means after withdrawing ₹25,000 monthly for 10 years, you would have received ₹30 lakh in total and still have ₹12.84 lakh invested at the end — assuming a 10% annual return.
