Enter your investment, monthly withdrawal, expected annual return, and time period.
How the calculator works (formula & assumptions)
Monthly rate: i = (1 + r)^(1/12) − 1
, where r
is the annual return.
Balance after n months (fixed withdrawal W):
B_n = P(1+i)^n − W · ((1+i)^n − 1) / i
Solve other ways:
Max sustainable withdrawal: W = P·i·(1+i)^n / ((1+i)^n − 1)
Required corpus for a target withdrawal: P = W · ((1+i)^n − 1) / ( i·(1+i)^n )
Depletion time (approx.): n = ln(W/(W − P·i)) / ln(1+i)
Assumptions: withdrawals at month-end; constant average return; no fees/taxes; step-up once every 12 months; “real” line deflates by inflation.
Tax note (India): Each SWP payment is a mix of your invested principal and any gains. Generally, only the gains portion is taxable. Rules differ for equity vs. debt funds and by holding period, and they change over time. This calculator does not compute taxes. Please verify with your advisor and latest official guidance.
SWP (Systematic Withdrawal Plan) – Explained
What is an SWP?
An SWP (Systematic Withdrawal Plan) lets you take a fixed amount from your mutual fund at regular intervals (usually monthly). The fund sells a few units each time. If returns beat your withdrawal rate, your corpus can grow. If returns are weak or withdrawals are high, the corpus can run out.
