One notified rate for the whole tenure

Each year: add the deposit (capped the way the scheme caps), then apply one annual rate. There is no monthly PPF credit in this model. There is no year-8 rate cut inside one run. When DEA changes the quarterly rate, type the new number and run the remaining years twice.

Modelling PPF when the rate changes. This is not a passbook. Confirm EEE treatment when you file.

When to use this calculator

Use this page to see how yearly PPF deposits could compound if one notified rate applied for the whole tenure you type.

How to read your result

Invested amount is the sum of yearly deposits (capped the way the slider allows). Interest and closing value follow one annual rate after each deposit in this model.

The rate on the slider is an assumption for the whole run. The government can change the notified PPF rate; this page does not schedule year-by-year rate cuts inside one illustration.

Key assumptions and limitations

  • One annual deposit, then one annual interest credit — not the passbook’s 5th-of-month rule in full detail.
  • Interest rate is whatever you type (often the current notified rate as a planning default).
  • EEE tax status, extension, and premature-closure rules are described in copy; they are not a filing engine.

Common mistakes

  • Treating one 15-year rate as a government promise for every remaining year.
  • Depositing after the 5th and expecting this yearly loop to match the passbook to the rupee.
  • Stuffing more than ₹1.5 lakh and assuming the extra still gets 80C and PPF interest.

What I check on PPF

  1. I run 6.5% as well as 7.1%. DEA can cut the notified rate.
  2. This model credits interest once a year. The passbook can disagree by a small amount.
  3. NRI and premature-closure rules are outside the loop. I do not pretend they are in it.

PPF is a government scheme parked at a bank or PO, not that bank's FD

The notified rate is set by DEA. Your passbook bank cannot match a private FD extra to keep you.

NRI rules, premature closure (after 5 years, specific grounds, 1% haircut), and loan against PPF are outside this loop.
