Reminder Library ยท Finance & Bills ยท Updated July 2026

PPF pays interest on the month's lowest balance. The 5th is the whole game.

One quiet rule decides your PPF returns: interest is calculated on the balance between the 5th and month-end. Deposit on the 6th and that month's contribution earns nothing.

Why PPF contributions underperform their owners

The 5th-of-month rule is barely advertised

Interest accrues on the lowest balance between the 5th and the last day. Most subscribers learn this years in, after dozens of post-5th deposits earned zero for their month.

The minimum deposit deadline sneaks up

Skip a whole financial year and the account goes dormant, with a penalty to revive. March 31st arrives faster than "I will do it next month" expects.

Fifteen-year products outlive attention

PPF is a decade-and-a-half commitment competing with this week's noise. Without a standing nag, even the disciplined drift into lump-sum panic deposits every March.

Squeezing the full rate from PPF

April lump sums beat March ones by a full year

The same deposit made on 2 April earns interest for twelve months; made the following March, for zero. Timing alone changes the outcome, and only a calendar knows.

The maturity and extension dates deserve their own nag

After year fifteen you can extend in five-year blocks, with or without contributions, but the election has a window. Set a one-off for the maturity year now, while you are thinking about it.

Track the passbook once a year

A yearly "update the PPF passbook and check interest credited" nag catches clerical misses. Fifteen years is long enough for at least one bank error, statistically.

Questions people ask

Monthly or yearly, which is better?

Yearly in early April earns the most interest if you have the lump sum. Monthly before the 5th is the honest second-best for salaried cash flow. Both beat the March scramble.

Does the same 5th rule apply to Sukanya Samriddhi?

Yes, the same lowest-balance mechanics apply. If you run an SSY account for a daughter, clone the nag: "Remind me on the 2nd of every month to deposit into SSY".

What happens if I forget a whole year?

The account turns dormant and needs a small penalty plus arrears to revive. The 1 March safety-net nag exists precisely so you never meet that form.

Can I combine this with my other investment nags?

Yes, "reminders" shows PPF, SIP and FD nags in one list, which is effectively your whole savings calendar on demand.

Is there a PPF deposit reminder app for WhatsApp?

You do not need one. NagMeLater works inside WhatsApp itself, so there is nothing to install, update or remember to open. Text it "Remind me on the 2nd of every month at 10am to deposit into PPF before the 5th" and the reminder exists. The best PPF deposit reminder app is the chat app you already check all day.
