Interest Rate
The PPF interest rate is the annual rate at which your PPF balance earns returns, currently set at 7.1% per annum and revised quarterly by the Government of India based on government bond yields.
Detailed Explanation
## How PPF Interest Rate Works The PPF interest rate is set by the Government of India and reviewed every quarter (January, April, July, October). Since April 2020, the rate has been steady at 7.1% per annum, compounded annually. ## How the Rate Is Determined Since 2016, small savings rates (including PPF) are linked to government bond yields. The PPF rate formula is: PPF rate = Average yield on 10-year government securities + 0.25% spread In practice, the government doesn't always follow this formula strictly. There have been instances where the calculated rate would have been lower, but the government maintained the existing rate for political or social reasons. ## Interest Calculation Method PPF interest is calculated monthly but credited annually (on March 31st). The monthly calculation uses the minimum balance between the 5th and the last day of each month. **Example for April:** - Balance on April 5th: Rs 3,00,000 - Deposit on April 20th: Rs 50,000 - Balance on April 30th: Rs 3,50,000 - Interest calculated on: Rs 3,00,000 (the lower of balances between 5th and 30th) - Monthly interest: Rs 3,00,000 x 7.1% / 12 = Rs 1,775 ## Historical Rate Trends PPF rates have ranged from 4.8% (1968) to 12% (1999-2000). The general trend has been downward over the last two decades as India's bond yields have fallen with declining inflation. The current 7.1% rate has been the longest stable period in PPF's history. ## Impact of Rate Changes Since rates can change quarterly, your actual maturity amount might differ slightly from a projection that assumes a constant rate. However, rate changes are typically small (0.1-0.2% at a time), so the impact is modest. Model different rate scenarios with our [PPF calculator](/) to understand the range of possible outcomes.
