Calculate PPF maturity, total investment and interest earned.
PPF (Public Provident Fund) is a long-term government-backed investment scheme in India offering fixed returns and tax benefits.
PPF returns are calculated annually using compound interest on yearly contributions.
Future Value = P × [(1 + r)^n - 1] / r
If you invest ₹1,00,000 yearly at 7.1% for 15 years, your investment grows significantly.
