How to Calculate SWP (Systematic Withdrawal Plan)
A Systematic Withdrawal Plan (SWP) lets you withdraw a fixed amount from your mutual fund at regular intervals. It's popular for generating regular income from investments.
SWP Remaining Balance Formula
Remaining = C × (1+r)^n - W × [((1+r)^n - 1) / r]
Where:
- C = Initial corpus (investment amount)
- r = Monthly return rate (annual return / 12)
- n = Number of months
- W = Monthly withdrawal amount
Step-by-Step:
- 1
Know your corpus
The total amount invested in the mutual fund.
- 2
Set withdrawal amount
How much you want to withdraw monthly.
- 3
Estimate return rate
Expected annual return of the fund.
- 4
Calculate sustainability
Check how long the corpus will last.
Worked Examples:
₹50L corpus, ₹30,000/month withdrawal
Corpus: ₹50,00,000Withdrawal: ₹30,000/monthReturn: 8%
Result: Corpus lasts ~30 years
With 8% annual return, monthly withdrawal of ₹30,000 is sustainable for about 30 years.
