Methodology. Compound interest: A = P × (1 + r/n)^(n×t), with n = compounding frequency per year. Inflation: Future cost = P × (1+i)^t (annual compounding). Purchasing power = P ÷ (1+i)^t. Same underlying math — one shows growth, the other shows erosion. India long-term inflation: ~6% (CPI). Real returns = nominal rate – inflation rate.
