SWP Sustainability Calculator India — Will Your Retirement Corpus Last Long Enough?

A Systematic Withdrawal Plan (SWP) allows you to withdraw a fixed amount from your mutual fund corpus every month while the remaining corpus continues to grow. The key risk: withdrawing too fast depletes the corpus. This calculator tells you exactly how long your corpus will last — and what withdrawal amount keeps it growing or stable indefinitely.

Safe withdrawal rate: ₹4L/year from ₹1 Cr corpus without depletion

Key risk: fixed withdrawal losing purchasing power over 20+ years

📐 Formula & How It Works

Corpus after each period: C(t+1) = C(t) × (1 + r/12) − Monthly Withdrawal

Corpus is depleted when C(t) reaches zero. The calculator projects this month-by-month.

Sustainable SWP = Corpus × (r/12) = amount where withdrawal equals monthly return.

Example: Corpus ₹1 Cr, 8% return. Monthly gain = ₹66,667. SWP of ₹66,667/month is perfectly sustainable (corpus never depletes). SWP of ₹80,000/month depletes corpus in approximately 21 years.

🛠️ How to Use This Calculator

  1. Step 1: Enter your total retirement corpus — combine all liquid assets: MF, FD, NPS lump sum, savings.
  2. Step 2: Enter expected annual return from portfolio (7–9% for conservative post-retirement mix).
  3. Step 3: Enter desired monthly withdrawal amount — how much you need to live on.
  4. Step 4: See the depletion timeline — how many years until corpus runs out at this withdrawal rate.
  5. Step 5: Adjust withdrawal to find the sustainable amount — the level at which corpus lasts 30+ years.
💡 Pro Tips
✓ Set SWP to 3–3.5% of corpus per year for inflation-adjusted sustainability over 30+ years.
✓ Maintain 2 years of expenses in liquid FD/savings as buffer — don't depend entirely on SWP for monthly cash.
✓ Step up SWP by 5% annually to account for inflation — corpus depletion is slightly faster but purchasing power is maintained.
✓ Equity-tilted portfolio (50%+ equity) in early retirement supports higher SWP rates — shift to debt later.
✓ Use SWP from debt component, keep equity invested — debt provides stability, equity drives long-term growth.

❓ Frequently Asked Questions

What is SWP and how does it work? +

SWP (Systematic Withdrawal Plan) lets you set up automatic monthly withdrawals from your mutual fund portfolio. The specified amount is redeemed each month and credited to your bank account. Remaining corpus stays invested and continues to earn returns.

What withdrawal rate is sustainable from a retirement corpus in India? +

A 3–4% annual withdrawal rate (i.e., ₹3–4L/year from ₹1 Cr) is generally sustainable for 25–30 years assuming 8–10% portfolio returns. Higher withdrawal rates (5–6%) are possible for shorter retirement periods of 15–20 years.

SWP vs pension vs annuity — which is better? +

SWP offers flexibility and retains growth potential. Annuity from insurance companies offers guaranteed income but locks in principal forever. Pension depends on the scheme. For most retirees, a hybrid approach works: annuity for 50% of basic needs (guaranteed), SWP for discretionary spending.

What fund type is best for SWP? +

Conservative hybrid funds or balanced advantage funds (BAF) are ideal — they provide equity growth with automatic rebalancing and lower volatility. Avoid pure equity for SWP — market crashes in early retirement years can permanently impair the corpus (sequence of returns risk).

How does inflation affect SWP sustainability? +

Inflation is the biggest risk. A fixed ₹50,000/month withdrawal in 2025 will have only ₹15,600 purchasing power in 2045 at 6% inflation. Step up your SWP by 6% annually (or annually review) to maintain purchasing power — this depletes corpus faster, requiring a larger initial corpus.

What is the sequence of returns risk in SWP? +

If markets crash early in your retirement while you're drawing down, the reduced corpus has less to benefit from the recovery. This is the opposite of SIP's rupee cost averaging. This is why conservative allocation in early retirement years (more debt) is recommended for SWP portfolios.
