What Is a Systematic Withdrawal Plan?
SWP stands for Systematic Withdrawal Plan. It is a mutual-fund facility through which an investor can provide a standing instruction to redeem a specified amount or number of units at regular intervals. Each withdrawal reduces the units held based on the applicable NAV and scheme rules.
This calculator models amount-based withdrawals from a projected corpus. It does not model units, daily NAV, tax lots, exit load, or transaction-specific deductions. SEBI investor material describes SIP and SWP as facilities to invest or redeem systematically, while scheme documents determine available dates, minimums, frequencies, and other operating terms.

How the SWP Projection Is Calculated
The entered annual fee is subtracted from expected annual return, and the net annual rate is converted to an equivalent monthly compounded rate. Each month, the calculator applies growth and any scheduled withdrawal in the selected order. The process continues until the duration ends or the corpus is depleted.

Frequency, Timing, and Increasing Withdrawals
Monthly, quarterly, half-yearly, and annual selections change how often the entered amount is withdrawn. Beginning-of-month timing withdraws first and then applies that month's modeled return; end-of-month timing applies the return first. An annual increase adjusts the withdrawal every 12 months after the first scheduled withdrawal.
Increasing withdrawals can be useful for exploring rising living expenses, but inflation and investment return do not move smoothly or predictably. A higher withdrawal path can materially shorten corpus longevity, particularly when weak returns occur early.
Why Compare Return Scenarios?
The lower and higher scenarios change gross annual return by two percentage points while keeping every other input the same. This shows sensitivity to a modest assumption change, but it does not represent the full range of possible outcomes or sequence-of-returns risk.
Constant returns are a simplifying assumption
Two portfolios with the same average return can support different withdrawals when gains and losses arrive in a different order. Consider stress testing lower returns and reviewing the plan regularly rather than treating one projection as guaranteed income.
Important: Projection, Not Financial Advice
Mutual-fund returns are market-linked and not guaranteed. Actual results depend on NAV movement, return sequence, scheme expenses, loads, taxes, deductions, withdrawal dates, available units, non-business days, and scheme terms. This educational tool does not recommend a fund, withdrawal rate, or investment strategy. Review official scheme documents and seek qualified advice when appropriate.
