Summary: After 20 years, cumulative withdrawals total ₹1,20,00,000 and remaining corpus is ₹2,64,46,714.
Summary: Withdrawing ₹50,000/month from ₹1,00,00,000 at 9% return delivers ₹1,20,00,000 in total income over 20 years while leaving ₹2,64,46,714 intact.

Formula & Mathematical Methodology: Iterative Monthly Corpus Depletion & Growth Relation

Bm = max(0,   Bm−1 − Wm) × (1 + r12)
B_m = max(0, B_{m−1} − W_m) × (1 + r / 12)
  • Bm: Portfolio balance at the end of month m
  • Wm: Scheduled withdrawal in month m
  • r: Nominal annual portfolio return rate

Rounding: Monthly simulation deducts withdrawal at start of month and compounds remainder at r/12.

Worked Example: ₹1,00,00,000 (₹1 Cr) Corpus with ₹50,000/Month SWP at 9% p.a. for 20 Years

A retiree withdraws ₹50,000/month (6% initial withdrawal rate) from a ₹1 Crore balanced portfolio earning 9% p.a.

  1. Annual withdrawal is ₹6,00,000, which is less than the ₹9,00,000 first-year investment return.
  2. Over 240 months, cumulative cash withdrawn is ₹1,20,00,000.
  3. Because the 9% return exceeds the 6% withdrawal rate, the remaining corpus grows to ₹2,68,94,328.
Result: Total cash withdrawn is ₹1.20 Cr with ₹2.69 Cr remaining after 20 years.

Frequently Asked Questions

What happens if I enable the Annual Withdrawal Inflation Increase?

Increasing withdrawals by 5%–6% annually to match inflation causes payouts to grow exponentially over time, which can deplete a corpus that would otherwise grow under fixed withdrawals.

How to Use the SWP Calculator (Systematic Withdrawal Plan): Practical Guide & Visual Analysis

Test whether your retirement or mutual fund corpus can sustain your monthly cashflow needs while the remaining balance continues to compound. Whether you are researching systematic withdrawal plan, retirement withdrawal calculator, corpus depletion calculator, monthly pension from corpus, this interactive tool helps you simulate monthly income withdrawals from an investment corpus, with optional annual inflation adjustments, and see whether the corpus lasts through retirement.

Interpreting the 3 Custom Visual Graphs & Key Outputs

As you adjust Starting Investment Corpus, Starting Monthly Withdrawal, Expected Annual Return on Corpus, Withdrawal Horizon, the calculator immediately computes Ending Corpus Balance (₹), Total Cumulative Cash Withdrawn (₹), Initial Annual Withdrawal Rate (%), Depletion Status / Year-by-Year Schedule and updates all three domain-specific SVG charts in real time. Instead of relying on a single static figure, you can inspect the primary domain diagram, component breakdown, and multi-point trajectory curve to see how changing your inputs shifts the final result. Use the Compare (up to 3 scenarios) button to evaluate side-by-side variations before making a decision.

Real-World Benchmark & Planning Tips (India & Global)

In our benchmark scenario (₹1,00,00,000 (₹1 Cr) Corpus with ₹50,000/Month SWP at 9% p.a. for 20 Years), Total cash withdrawn is ₹1.20 Cr with ₹2.69 Cr remaining after 20 years. Keep in mind that withdrawals occur at the start of each month; remaining balance earns r/12 for that month.
