What Is SWP Calculator?
A Systematic Withdrawal Plan (SWP) Calculator helps you estimate how long a lump-sum corpus will last when you withdraw a fixed amount every month. It is widely used by retirees and senior citizens who want a steady, predictable monthly income from their mutual fund investments without fully depleting their corpus. The key insight: if your remaining corpus earns more than you withdraw each month, it can sustain withdrawals indefinitely — the SWP calculator shows you exactly where that balance point lies.
How SWP Calculator Helps You
Retirement planning is as much about managing withdrawals sustainably as it is about building a corpus. The SWP calculator helps you find the right balance between income and longevity.
- Estimate how many years your retirement corpus will sustain your chosen monthly withdrawal
- Find the optimal monthly withdrawal amount that makes your corpus last the longest
- Understand how the return rate on remaining funds extends — or shortens — how long money lasts
- Compare different corpus sizes and withdrawal amounts before finalising your retirement plan
- See the impact of a Step-Up SWP: increasing annual withdrawal to keep pace with inflation
How Does SWP Calculator Work?
Each month, the remaining corpus earns the expected monthly return (annual rate ÷ 12), and then your chosen withdrawal amount is subtracted. The calculator repeats this monthly cycle — grow, then withdraw — until the corpus is exhausted or 50 years is reached. For example, a ₹20 lakh corpus at 8% p.a. with ₹20,000/month withdrawal lasts approximately 15 years. The critical insight: if your monthly return (corpus × rate ÷ 12) equals or exceeds your withdrawal, the corpus never depletes — a state of perpetual withdrawal known as a "self-sustaining SWP."

Frequently Asked Questions
For most retirees in higher tax brackets, SWP from a balanced or debt mutual fund provides better post-tax income than a bank FD. FD interest is taxed at your full slab rate. With equity/hybrid funds, long-term capital gains above ₹1.25 lakh are taxed at only 12.5% — significantly lower than 20%–30% slab rates.
If the monthly returns on your corpus exceed your monthly withdrawal, the corpus grows over time — meaning your SWP can last indefinitely. The calculator shows "50+ yrs" in this scenario. For example, a ₹1 crore corpus at 9% p.a. earns ₹75,000/month — any withdrawal below this is self-sustaining.
A Step-Up SWP increases your monthly withdrawal by a fixed percentage each year — typically 5%–6% — to match inflation. Without a step-up, ₹20,000/month today has the purchasing power of only ~₹12,200 after 10 years at 5% inflation. A step-up SWP helps maintain your real standard of living through retirement.
Balanced Advantage Funds and Hybrid Funds are popular for SWP — they provide stable returns with equity upside while limiting downside risk. Debt funds work well for conservative retirees. Avoid pure equity funds for short-tenure SWP (under 5 years) due to market volatility risk.
