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 Over 240 months, cumulative cash withdrawn is ₹1,20,00,000.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Result: Total cash withdrawn is ₹1.20 Cr with ₹2.69 Cr remaining after 20 years.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.

SWP Calculator (Systematic Withdrawal Plan): inputs, method, and how to read the result

Project remaining investment balance, cumulative withdrawals, and corpus sustainability over time.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Display Currency: Amounts are treated in the selected currency; no foreign-exchange conversion is applied.
  • Starting Investment Corpus: Initial lump-sum portfolio value (e.g. ₹1 Crore = 1,00,00,000).
  • Starting Monthly Withdrawal: First-year monthly SWP payout.
  • Expected Annual Return on Corpus: Annual return earned by the remaining invested balance.

What the calculation includes

With the default values shown, Ending Corpus After Withdrawal Period is USD 26,446,714.00. The calculation follows Iterative Monthly Corpus Depletion & Growth Relation; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Starting Investment Corpus from 10,000,000 ₹ INR to 11,000,000 ₹ INR changes Ending Corpus After Withdrawal Period from USD 26,446,714.00 to USD 32,455,866.00. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Withdrawals occur at the start of each month; remaining balance earns r/12 for that month.
  • Does not simulate sequence-of-returns risk (market drawdowns in early retirement years).

Scope: India & Global Check the assumptions and limitations against your situation before relying on the estimate.
