How to Use This Calculator
KVP Maturity tab
Enter your investment amount (e.g. ₹5,00,000). The calculator shows the maturity amount (your money doubled), the maturity period of 115 months (9 years 7 months), and the effective annual rate. A year-by-year growth table shows how your investment compounds at 7.5% annually until it doubles.
After-Tax Returns tab
Enter the same investment amount and select your income tax slab. KVP interest is fully taxable at your slab rate under "Income from Other Sources" — there is no Section 80C benefit and no TDS deducted at source. The calculator shows gross interest, tax payable, post-tax maturity amount, and effective post-tax rate across all slab brackets so you can assess the real return.
KVP vs PPF vs FD tab
Enter your investment amount and tax slab. The calculator compares three instruments over ~10 years: (A) KVP at 7.5% (taxable, no limit), (B) PPF at 7.1% (tax-free EEE, but capped at ₹1.5L/year), and (C) Fixed Deposit at 7% (taxable). Each shows post-tax maturity so you can pick the best option for your situation.

The Formula
KVP compounds annually at a fixed interest rate. The maturity amount is guaranteed to be double the investment amount at the end of the doubling period:
Maturity = Principal × 2
Year-by-year compounding:
Balancen = Balancen-1 × (1 + r)
Where:
r = Annual interest rate (7.5% = 0.075)
n = Year number (1 to 10)
Doubling period formula:
Period (months) = ln(2) / ln(1 + r) × 12
= ln(2) / ln(1.075) × 12
= 0.6931 / 0.0723 × 12
≈ 115 months (9 years 7 months)
After-tax return:
Tax = (Maturity − Principal) × Slab Rate
Post-tax Maturity = Maturity − Tax
Effective Post-tax Rate = ((Post-tax Maturity / Principal)12/115 − 1) × 100
Taxation rules (FY 2025-26):
KVP interest: Taxable at income slab rate under "Income from Other Sources".
No TDS deducted at source. No Section 80C deduction available.
Compare with PPF: EEE status (fully tax-free, but capped at ₹1.5L/year).
The guaranteed doubling makes KVP one of the simplest savings instruments — invest any amount above ₹1,000 and it will exactly double in 115 months at the current 7.5% rate.
Example
Farmer Suresh — invests ₹5,00,000 in Kisan Vikas Patra at the local post office
Suresh (45) is a farmer in Maharashtra who sold part of his harvest and has ₹5,00,000 in cash. He wants a safe, guaranteed investment and does not trust private banks. His village post office recommends Kisan Vikas Patra. Suresh wants to know: how much will he get at maturity, and how much tax will he pay?
Step 1: KVP Maturity
Step 2: After-tax calculation (Suresh is in 10% slab)
Step 3: Why KVP works for Suresh
Suresh invests the full ₹5L in KVP at his village post office. After 9 years 7 months, he receives ₹10L (doubled). After paying ₹50,000 in tax, he nets ₹9.5L — a solid return for a zero-risk government instrument with no investment ceiling.
