Summary: SIP builds $27,475,247.00 in 20 years, which then funds $28,800,000.00 in SWP withdrawals over 20 years.
Summary: Phase 1 (Accumulation): Investing $20,000.00/month (+5%/yr step-up) for 20 years at 12% builds a retirement corpus of $27,475,247.00 ($27,500,000.00). Phase 2 (Distribution): Switching that corpus to a 8% p.a. yield and withdrawing $120,000.00/month over 20 retirement years pays out $28,800,000.00 and leaves $64,211,455.00.

Formula & Mathematical Methodology: Coupled Accumulation-Distribution Difference Equations

Accumulation:   Bm = (Bm−1 + Py)(1 + racc12)
SWP Phase:   Bk = max(0,   Bk−1 − Wk)(1 + rret12)
Phase 1: B_m = (B_{m−1} + P_y)(1 + r_acc/12); Phase 2: B_k = max(0, B_{k−1} − W)(1 + r_ret/12)
  • racc, r_ret: Pre-retirement growth rate and post-retirement conservative yield
  • W: Monthly SWP pension withdrawal in retirement

Rounding: Rounded to nearest rupee.

Worked Example: ₹20,000/Mo SIP (+5%/Yr) for 20 Years @ 12% → ₹1,20,000/Mo SWP for 20 Years @ 8%

Build a corpus over 20 working years and withdraw ₹1.20 Lakh/month for 20 retirement years.

  1. Phase 1 builds a retirement handover corpus of ₹2,68,54,539 (~₹2.69 Cr) from ₹79.36L invested.
  2. Phase 2 withdraws ₹1,20,000/month (₹2.88 Cr total payouts over 20 years) while the balance earns 8% p.a.
  3. After 20 years of retirement payouts, ₹6,27,93,310 remains intact.
Result: Builds ₹2.69 Cr at retirement, pays ₹2.88 Cr in SWP income, and remains 100% sustainable.

Frequently Asked Questions

Why should Phase 2 use a lower return rate than Phase 1?

During retirement withdrawals, shifting a portion of your corpus into lower-volatility hybrid or debt funds (earning 7%–9%) protects your monthly pension from equity bear markets.

Interpreting the 3 Custom Visual Graphs & Key Outputs

As you adjust Display Currency, Phase 1: Starting Monthly SIP, Phase 1: Annual SIP Step-Up, Phase 1: Accumulation Duration, the calculator immediately computes Corpus Built at Retirement Handover (₹), Total SWP Pension Paid Over Retirement (₹), Ending Legacy Balance After SWP (₹), Sustainability Status 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 (₹20,000/Mo SIP (+5%/Yr) for 20 Years @ 12% → ₹1,20,000/Mo SWP for 20 Years @ 8%), Builds ₹2.69 Cr at retirement, pays ₹2.88 Cr in SWP income, and remains 100% sustainable. Keep in mind that assumes portfolio is rebalanced from growth equity (r_acc) into a conservative bucket (r_ret) at retirement.
