Retirement Corpus Formula

How your total retirement corpus is calculated based on monthly savings and the power of long-term compounding.

Retirement Corpus Formula
C = P × { [(1 + r)n − 1] / r } × (1 + r)
r = Annual Return ÷ 12  ·  n = Years to Retirement × 12
What Each Variable Means
C
Retirement Corpus
Total wealth accumulated at the time of retirement
P
Monthly Savings
Fixed amount you save and invest every month
r
Monthly Return Rate
Expected annual return ÷ 12 (e.g. 12% → 0.01/month)
n
Total Months
Years to Retirement × 12 (e.g. 25 years = 300 months)
Worked Example

A 30-year-old plans to retire at 60, saving ₹15,000/month at 12% p.a.:

  • P = ₹15,000/month
  • Annual Return = 12% → r = 12 ÷ 100 ÷ 12 = 0.01
  • Years = 30 → n = 30 × 12 = 360 months

Applying the formula:

  • C = 15000 × [(1.01)360 − 1] / 0.01 × 1.01
  • C = 15000 × [35.9496 − 1] / 0.01 × 1.01
  • C = 15000 × 3494.96 × 1.01
  • C = ₹5,29,73,681
