SWP vs FD Interest for Monthly Income: Which Lasts Longer in Retirement?

Retirement · 26 October 2026 · Plan Our Future

An FD pays a fixed interest that stops growing while your costs rise ~6-7% a year, while an SWP lets you raise withdrawals yearly and keep part of the corpus invested for growth. For most retirees, a withdrawal rate near 4-5% of the corpus is the zone where an SWP can plausibly last 25-30 years, under assumed returns. Neither is guaranteed.

How each one actually works

FD interest: you park the corpus, the bank pays interest monthly or quarterly. The corpus stays at Rs.1 crore, but the income is fixed.
SWP (Systematic Withdrawal Plan): the corpus stays invested in mutual funds and you withdraw a set amount every month. Each withdrawal sells a few units, so the balance can grow or shrink depending on returns.

The inflation problem with FD income

Say Rs.1 crore earns 7% in an FD, which is Rs.7 lakh a year (about Rs.58,000 a month) before tax. Interest is taxed at your slab rate, so the in-hand figure is lower. The bigger issue is that the number never rises.

Year	FD income (fixed)	What it buys, at 6% inflation
1	Rs.7.0 lakh	Rs.7.0 lakh
10	Rs.7.0 lakh	about Rs.3.9 lakh
20	Rs.7.0 lakh	about Rs.2.2 lakh

Your corpus is safe in nominal terms, yet your lifestyle quietly shrinks by more than half.

What an SWP changes

Suppose the same Rs.1 crore sits in a balanced mix, with an assumed long-term return of about 9% (equity near 11-12%, debt 6-7%). You start with Rs.4.8 lakh a year (4.8%) and raise the withdrawal 6% every year to match inflation.

While returns stay near the assumption, the corpus can last well beyond 25 years.
If the first 3-5 years are poor, you are selling more units at low prices. That is sequence-of-returns risk, and it can drain the corpus much sooner.
Gains in an SWP are taxed only on the profit portion of each withdrawal, which is often lighter than slab-rate interest. Rules differ by fund type, so check the current rates with a CA.

A simple middle path: the bucket approach

Bucket 1 (1-2 years of expenses): FD or a liquid option, so you never sell equity at a bad time.
Bucket 2 (next 3-5 years): debt-oriented holdings that refill Bucket 1.
Bucket 3 (the rest): equity-oriented, funding the long run against inflation.

The SWP runs from Bucket 1, refilled yearly. This is the same de-risking idea as a glide path: safer money near the spending, growth money further away.

Where this fits your plan

Planning Our Future builds your retirement goal with an inflation-adjusted corpus, and a separate SIP for it that shifts from equity toward debt and gold as retirement nears. That gives you a realistic corpus to run an SWP from, instead of guessing.

FAQ

Q. What withdrawal rate is considered safe?

A. Many planners treat 3.5-4.5% of the starting corpus as a cautious zone for a 30-year retirement in India, rising with inflation. Higher rates raise the risk of running out.

Q. Can I use both an FD and an SWP?

A. Yes. Many retirees hold 1-2 years of expenses in FDs for stability and run an SWP from the growth portion.

Q. Is an SWP guaranteed?

A. No. Withdrawals are fixed by you, but the fund value moves with markets. Poor early returns can shorten how long the corpus lasts.

Q. Which is better if I need the money for only 5-7 years?

A. For a short window, the stability of FD or debt-oriented options usually matters more than inflation protection.
