How to Use This Calculator
SWP Plan tab
Enter your total mutual fund corpus, desired monthly withdrawal, and expected annual return. The calculator simulates month-by-month withdrawals and shows how long your corpus lasts, remaining balance at 5/10/15/20/25/30 year milestones, and estimated annual LTCG tax. Use this to plan your retirement income or regular cash flow from investments.
SWP vs FD tab
Compare the same corpus invested in an equity-oriented hybrid mutual fund (SWP) versus a Fixed Deposit. See the tax difference: SWP withdrawals are taxed only on the gains portion at 12.5% LTCG, while FD interest is 100% taxable at your slab rate. The calculator shows annual tax savings, post-tax income, and corpus projection for both options.
Sustainable Withdrawal Rate tab
Enter your retirement corpus, expected portfolio return, and desired duration (e.g. 30 years). The calculator finds the maximum monthly withdrawal that makes your corpus last exactly that long. It also shows a scenario table for different withdrawal rates (3% to 8%) so you can see the trade-off between monthly income and corpus longevity.

The Formula
SWP is simulated month-by-month. Each month, the corpus grows by the monthly return rate, then the withdrawal amount is deducted:
Balancen = Balancen-1 × (1 + r) − W
Where:
Balancen = Corpus balance after month n
r = Monthly rate of return (annual rate / 12 / 100)
W = Monthly withdrawal amount
Sustainable Withdrawal (PMT formula):
W = PV × r × (1 + r)n / [(1 + r)n − 1]
Where:
PV = Present value (corpus)
r = Monthly rate of return
n = Total months
W = Maximum monthly withdrawal for corpus to reach zero at month n
SWP Tax (FY 2025-26):
Each SWP withdrawal = partial redemption. Only gains portion is taxable.
Equity/Hybrid MF (held > 1 year): LTCG 12.5% on gains above ₹1,25,000/year
Equity/Hybrid MF (held < 1 year): STCG 20% on entire gains
Debt MF (post April 2023): Gains taxed at income slab rate, no indexation
FD interest: 100% taxable at income slab rate (TDS under Section 194A)
The key insight: in an SWP withdrawal of ₹30,000, if the cost basis of redeemed units is ₹24,000 and current value is ₹30,000, only ₹6,000 (the gains) is taxable. The remaining ₹24,000 is your own principal returning to you tax-free. This is why SWP is dramatically more tax-efficient than FD interest.
Example
Rajesh — Retired banker in Pune, ₹50 lakh corpus, ₹30,000/month SWP
Rajesh retired at 60 with ₹50,00,000 in a balanced advantage fund. He starts an SWP of ₹30,000/month, expecting 9% annual returns. He wants to know: how long will his corpus last, and how much tax does he save vs an FD?
Step 1: SWP Plan calculation
Step 2: Corpus projection
Step 3: SWP vs FD tax comparison (annual)
Rajesh's ₹50 lakh corpus supports ₹30,000/month for 27 years via SWP. He saves over ₹1 lakh per year in taxes compared to an FD. Over 20 years, that is ₹20+ lakh in tax savings alone.
