PPF Calculator
Retirement fund. Child's education. Long-term wealth building. Whatever the goal, PPF remains one of the safest ways to get there. Guaranteed returns, zero risk, and completely tax-free maturity. No other investment offers this combination. But how much should you deposit yearly to reach your target corpus? And what will 15 years of compounding actually deliver? The public provident fund calculator answers both.

What is a PPF Calculator?
A PPF calculator is a financial planning tool that estimates your Public Provident Fund maturity amount based on yearly deposits, interest rate, and investment duration. It shows total corpus at maturity, interest earned, and year-by-year growth.
Instead of manually computing compound interest over 15 years, the calculator does it instantly. Change deposit amount – see new maturity value. Adjust tenure with extensions – see updated corpus. Simple inputs, clear outputs.
How it Helps Investors
- Plan realistic savings goals – Know exactly what ₹50,000 yearly versus ₹1.5 lakh yearly delivers after 15 years. Set deposits based on target corpus, not guesswork.
- Understand compounding power – See how interest accelerates in later years. Year 1 interest is small. Year 15 interest is massive. Calculator makes this visible.
- Compare scenarios quickly – What if rate drops to 6.5%? What if you extend 5 more years? Run multiple calculations in minutes.
- Tax planning – Understand Section 80C benefit alongside maturity projection. See complete tax savings over investment period.
- Align with life goals – Child's education in 15 years? Retirement planning? Calculator shows if PPF deposits match required corpus.
How to Calculate PPF Interest?
Input Parameters:
- Yearly deposit amount – How much you'll invest annually. Minimum ₹500, maximum ₹1.5 lakh per financial year. Can vary year to year, but calculator typically assumes fixed annual deposit.
- Investment duration – PPF has 15-year lock-in. Calculator defaults to this. Extensions in 5-year blocks possible after maturity.
- Deposit frequency – Lump sum yearly or monthly instalments. Both reach same annual total, but timing affects interest calculation.
Interest Rate Assumptions
- Current PPF rate: 7.1% per annum (as of FY 2025-26).
- Government reviews and announces rates quarterly. Rate can change, but calculator uses current or user-specified rate for projections.
Important: PPF interest compounds annually but calculates on lowest balance between 5th and end of each month. Deposit timing matters.
Calculating Maturity Amount and Interest Earned
So, how to calculate PPF interest easily? The calculator uses compound interest formula:
A = P × [(1 + r)^n - 1] / r × (1 + r)
Where:
- A = Maturity amount
- P = Annual deposit
- r = Annual interest rate (as decimal)
- n = Number of years
PPF calculation example:
₹1,00,000 yearly at 7.1% for 15 years:
- Total deposited: ₹15,00,000
- Interest earned: ₹12,12,139
- Maturity amount: ₹27,12,139
Calculator handles this instantly. Just input your numbers.
Benefits of Using a PPF Calculator
Accurate Financial Planning
No guesswork. Enter deposit amount, see exact maturity value. Adjust deposits until maturity matches your goal.
Planning ₹30 lakh for child's education? Calculator shows ₹1.1 lakh yearly needed at 7.1% for 15 years. Now you have a target.
Comparing with Other Investment Options
Run PPF calculation, then compare with ELSS or FD returns. Same ₹1.5 lakh yearly:
- PPF at 7.1% for 15 years: ₹40.68 lakh (tax-free)
- FD at 6.5% for 15 years: ₹38.47 lakh (taxable – net ₹30-32 lakh after tax)
A public provident fund calculator makes comparison tangible.
