Fixed Deposit Monthly Interest Payout Explained

A monthly-payout fixed deposit trades away compounding for a steady stream of monthly income — a genuinely different product from a cumulative FD, even when both start with the identical principal, rate, and term. Understanding the tradeoff means understanding exactly what’s given up.

How the monthly payout is actually calculated

A ₹5,00,000 FD at a 7% annual rate pays out approximately ₹2,917 every month for the term of the deposit, with the full ₹5,00,000 principal returned at maturity. Because this interest is paid out and spent (or moved elsewhere) each month rather than being added back to the principal, it never itself earns additional interest — which is the core tradeoff against a cumulative FD.

Why a cumulative FD produces a larger total

On this ₹5,00,000 example over 5 years, the cumulative FD’s compounding advantage adds up to roughly ₹32,389 more than the monthly-payout FD’s total (all payouts received plus the principal back) — even before considering what the monthly payouts might have earned if reinvested elsewhere.

Why someone still chooses monthly payout over cumulative

The monthly-payout structure exists specifically because some depositors need regular income now rather than a larger lump sum later — a retiree covering monthly expenses from FD interest is optimizing for cash flow, not total return, and the lower total is the explicit cost of that choice.

Feature	Cumulative FD	Monthly-payout FD
Interest compounding	Yes (typically quarterly)	No
Interest paid out	Only at maturity	Every month
Total return over the term	Higher	Lower
Best suited for	Growing a lump sum	Regular income needs

FAQ

Is the monthly payout amount the same every month for the whole term? Yes, on a fixed-rate FD — since it’s calculated as simple interest on the unchanging principal, the monthly payout stays constant unless the FD itself allows a rate reset, which fixed-term FDs typically don’t.

Does the Simple Interest Calculator model a monthly-payout FD accurately? Yes — since the payout itself doesn’t compound, simple interest math (principal × rate ÷ 12) is the correct model for the payout amount, even though the overall product is still called a “fixed deposit.”

Is FD interest income taxable? In most jurisdictions, yes, interest income from fixed deposits is generally taxable as regular income — specific treatment (including any TDS withholding) depends on local tax rules and the depositor’s overall tax situation.

Can I switch a monthly-payout FD to cumulative mid-term? Generally no — the payout structure is typically fixed at the time the FD is opened, so this choice is usually made upfront rather than changed mid-term without breaking and reopening the deposit.

How does a monthly-payout FD compare to a cumulative one held for the same term? See Cumulative vs. Non-Cumulative Fixed Deposits Compared for a fuller side-by-side comparison beyond just the payout mechanics.

Does the Compound Interest Calculator show the cumulative FD comparison? Yes — entering the same principal, rate, and term with quarterly compounding produces the cumulative FD’s maturity value shown above, making it a useful direct comparison against a monthly-payout total.
