What Is a Retirement Corpus?
A retirement corpus is the lump sum you need at retirement to fund the rest of your life without earned income. It must cover your living expenses, healthcare, and any goals (travel, gifting) while keeping up with inflation, which usually doubles costs roughly every 12 years at 6%.
This calculator computes:
- Corpus at retirement — future value of your monthly savings at your chosen return rate.
- Monthly pension — annuity-style withdrawal that exhausts the corpus over your post-retirement life.
- Inflation-adjusted expenses — how much your target monthly expense will cost in future rupees.
- Surplus or shortfall — whether your savings rate is on track.
How the Numbers Work
Three formulas drive the projection:
Corpus = S × [((1 + i)n − 1) / i] × (1 + i)
Pension = Corpus × i / [1 − (1 + i)−m]
Inflated Expense = E × (1 + π)y
- S = monthly savings, i = monthly return rate, n = months to retirement.
- m = months in retirement, E = current monthly expense.
- π = annual inflation, y = years to retirement.
Retirement Savings Benchmarks
| Age | Savings Target | Rationale |
|---|---|---|
| 30 | 1× annual salary | Foundation built; emergency fund + early SIPs |
| 40 | 3× annual salary | Compounding starts to bite; aggressive equity allocation |
| 50 | 6× annual salary | De-risk gradually; rebalance to balanced funds |
| 60 | 10× annual salary | Ready for retirement; mix of annuity, debt, equity |
