Retirement Corpus Calculator Guide
The Formula We Use
Annual Expenses at Retirement = Current Annual Expenses × (1 + Inflation Rate)^Years Until RetirementCorpus Needed = Annual Expenses at Retirement × Withdrawal FactorWithdrawal Factor = [(1 - (1 + r)^(-N)) ÷ r]wherer= post retirement return,N= retirement years- This assumes systematic withdrawals each year, adjusted for returns.
Example Calculation
- Annual Expenses at Retirement = 40,000 × (1+0.05)^20 ≈ $106,096
- Withdrawal Factor = (1 - (1+0.06)^(-25)) ÷ 0.06 ≈ 12.78
- Corpus Needed = 106,096 × 12.78 ≈ $1,356,782
- You need about $1.36M at retirement to sustain $106K per year for 25 years.
