Kalculate

Retirement Withdrawal Calculator for India

See how long your corpus will last and how much you can safely withdraw each month — with inflation-growing withdrawals (a smarter SWP) and an optional 3-bucket strategy. Private by design: no signup, nothing stored.

Withdrawal strategy

Different return assumptions, not just different mechanics: Simple applies one flat rate (8%) to your whole corpus. 3-bucket keeps most of it invested in equity long-term (12%), only touched when it has gained — a small yearly edge that compounds into a much bigger gap the longer your horizon and the lower your withdrawal rate.

The verdict
Runs out at age 77
₹1 Cr can't sustain ₹50,000/month (in 2026 money) growing with inflation until 90. Lower the spend, or see the safe number →
The corpus runs out at age 77.

Withdrawals grow every year — general spending at 6%, the medical 15% at 10% — while the remaining corpus earns 8%. Never a flat number.

How the withdrawal calculator works

  1. Enter your corpus and spendingin today's money, plus the ages withdrawals start and end.
  2. We simulate every year— each year's withdrawal rises with inflation (general 6%, medical 10%) while the rest of the corpus keeps earning a return.
  3. Get the verdict— the age your money lasts to, or the safe monthly amount you can draw, with a year-by-year schedule in both nominal and today's-money terms.
  4. Try the 3-bucket strategy to see a crash-resistant way to structure and draw down the corpus.

Frequently asked questions

How long will my retirement corpus last?
Enter your corpus, your monthly spending in today's money, and the age you'll plan to, and the calculator simulates each year — growing withdrawals with inflation while the remaining corpus earns a return — to show the exact age your money runs out (or that it lasts the full horizon).
How much can I safely withdraw each month?
Switch to 'How much can I draw?' and set your horizon; the calculator solves for the highest starting monthly withdrawal that lasts your whole plan, rising with inflation each year. In India, sustainable rates are typically lower than the US 4% rule (closer to 3–3.5%) because inflation is higher.
Is this an SWP (Systematic Withdrawal Plan) calculator?
Yes — but an inflation-aware one. Unlike most SWP calculators that assume a flat monthly withdrawal, this grows your withdrawal every year (general spending at 6%, medical at 10%) so your purchasing power holds through retirement.
What is the 3-bucket withdrawal strategy?
It splits your corpus by when you'll spend it: a short-term bucket (0–3 years, safe), medium (4–8 years, ~25% equity), and long-term (9+ years, ~50% equity). You spend from the safe bucket and only refill from equity after good years — so a market crash can't force you to sell at a loss. Kalculate shows the allocation and the year-by-year moves.
I retire in a few years — can I enter today's corpus?
Yes. Enter what you have today and the age withdrawals begin; the calculator grows the corpus to that age at an editable rate before the drawdown starts.
Why does the 3-bucket strategy end with a much bigger corpus than Simple?
Because the two strategies assume different returns, not just different withdrawal mechanics. 'Simple' applies one flat, conservative rate (8% by default) to your entire corpus every year. '3-bucket' assumes real asset-class returns instead — cash/debt for near-term spending, but the long-term portion (often the majority of your corpus) stays invested in equity (12% by default) and is rarely touched, only refilling the nearer buckets after good years. A 1-4 percentage point return edge sounds small, but compounded over a multi-decade retirement — especially when your withdrawal rate is well below the return rate, so the corpus keeps growing instead of shrinking — it produces a dramatically larger ending balance. This is the standard math of compounding over long horizons, not a bug or a bucket-strategy trick.
