About this calculator
In-depth guide for the KVP calculator — formulas, examples, and official sources for India.
Introduction
KVP is a post office certificate where your deposit approximately doubles at maturity. It suits investors who want a simple doubling target without market risk. There is no Section 80C deduction on KVP.
What this calculator does
Estimate when your KVP amount doubles and total maturity value. KVP works for conservative investors with a lump sum who can lock money for the full doubling period (roughly 9–10 years at current rates). It is not ideal if you need liquidity within 2–3 years.

- ₹1,00,000 at 7.5% → doubles to ≈ ₹2,00,000 in about 9.6 years
Lock-in and premature rules
Premature encashment is allowed after 2.5 years with reduced returns. Maturity period depends on the notified rate at purchase — use this calculator to see when ₹1 lakh becomes ₹2 lakh.
