PPF, EPF, fixed deposits and recurring deposits on this site follow Indian product rules, including quarterly compounding on FD and RD. You can display the same math in USD, GBP, EUR, AUD, CAD or INR. A US 401(k), UK pension or Australian super account is a different product, so do not treat the balance as a local retirement account.
