Frequently asked questions
How is PPF maturity calculated?
PPF compounds annually. The maximum benefit comes from depositing the full annual amount before April 5, so the entire year's interest accrues. With annual deposit P, rate r and n years (annuity due):
Maturity = P × [((1+r)n − 1) / r] × (1+r)
Example: ₹1,50,000 × 15 years × 7.1% → maturity ≈ ₹40.7 lakh, of which ₹22.5 lakh is principal and ₹18.2 lakh is tax-free interest.
What's the current PPF rate?
PPF rate is reset every quarter by the Department of Economic Affairs (Ministry of Finance). Recent quarterly rates have been 7.1% per annum. The calculator defaults to 7.1%; override if you're projecting a different rate.
How does FD compounding work?
Most banks compound FD interest quarterly. Each quarter the interest is added to the principal; the next quarter's interest is on the new base. Formula:
Maturity = P × (1 + r/m)m×n — where m is compounding periods/year (4 quarterly, 12 monthly).
For a 5-year FD of ₹5L at 7% quarterly: maturity ≈ ₹7.07L (₹2.07L interest).
Are PPF and FD interest taxable?
PPF: fully tax-exempt — deposit (under 80C up to ₹1.5L), interest, and maturity are all tax-free (EEE category).
FD: interest is added to your taxable income at slab rate. TDS at 10% if FD interest in a year exceeds ₹40,000 (₹50,000 for senior citizens). Senior citizens get an additional ₹50,000 deduction under Section 80TTB.
Can I extend my PPF beyond 15 years?
Yes. After the initial 15 years, you can extend in 5-year blocks — with or without further contributions. Extension with contributions: continue depositing ₹500–₹1.5L/year. Extension without contributions: account keeps earning interest, you can make 1 partial withdrawal per year.
The calculator accepts up to 50 years for long-horizon planning.
