How this is calculated

Formula

real value = P × (1 + r)ⁿ ÷ (1 + π)ⁿ

P
= amount today
r
= annual return
π
= annual inflation
n
= years

With your numbers

  1. 1Grow it at the returnP × (1 + r)ⁿ₹1,00,000 × (1 + 12.00%)^10 = ₹3,10,585
  2. 2Deflate to today’s rupees÷ (1 + π)ⁿ₹3,10,585 ÷ (1 + 6.00%)^10 = ₹1,73,429
  3. 3Real return(1 + r) ÷ (1 + π) − 1= 5.66% a year
Worth in today’s money₹1,73,429
  • Return minus inflation would give 6.00%; the Fisher relation gives 5.66%. The gap grows with the rates and the years.
  • Tax on the return is not deducted, so for a taxable investment the real return after tax is lower still.
