Which builds more wealth in 15 years, a ₹10,000/month investment in PPF or SIP?

A ₹10,000 monthly investment for 15 years would grow to around ₹32.5 lakh, assuming the PPF interest rate remains at 7.1%. As PPF maturity proceeds are tax-free, the entire amount remains with the individual. The same investment in equity SIP at 10% annual return would grow to ₹41.8 lakh. However, the corpus would be roughly ₹38.9 lakh after paying taxes.
