What is Kisan Vikas Patra (KVP)?
Kisan Vikas Patra (KVP) is a small-savings certificate from India Post that is designed to double your invested amount in a fixed period (currently 115 months at 7.5%). Available at post offices and select banks, KVP is a safe, low-risk option — the principal is government-guaranteed.
Formula
KVP is structured to double the principal at maturity:
Maturity = Principal × 2 Effective annual rate (from doubling time): r = (2^(12 / doubling_months) − 1) × 100 Current: 7.5% p.a., doubles in 115 months ≈ 9 years 7 months.
