# A 7% fixed deposit: what is left after tax and inflation

> A ₹10 lakh FD at 7 percent shows ₹14 lakh after five years. After 30 percent tax on the interest it is ₹12.7 lakh. After 6 percent inflation, it buys what ₹9.5 lakh buys today. The deposit is safe. The purchasing power is not.

Fixed deposits are famous for one thing: you know exactly what number you will get. What the number will buy is a different question. Three steps stand between the bank's headline rate and your real gain.

> **In short**
> - ₹10 lakh at 7% for 5 years: **₹14.03 lakh** before tax.
> - If the interest is taxed at **30 percent**, the effective rate is 4.9% and you get **₹12.70 lakh**.
> - With **6 percent inflation**, that ₹12.70 lakh buys about **₹9.49 lakh** worth of today's goods: slightly less than you started with.
> - Lower tax slabs and higher rates look better, but the exercise is worth doing with your own numbers.

## Step 1: the headline

Compounded yearly, ₹10 lakh at 7 percent grows to ₹14.03 lakh in five years. That is the number the bank puts on the brochure and the one the FD calculator shows first.

## Step 2: tax on the interest

FD interest is added to your income and taxed at your slab rate. For someone in the 30 percent slab, 30 percent of each year's interest goes in tax, so the 7 percent behaves like 4.9 percent (7 × 0.7). The lower your slab, the smaller the loss.

## Step 3: inflation

If prices rise 6 percent a year, ₹100 today needs ₹133.80 in five years to buy the same things. Dividing the after-tax balance by 1.338 gives its value in today's rupees.

**₹10 lakh in a 7% FD after 5 years**

| Step | Value |
| --- | --- |
| On the bank statement | ₹14.03 lakh |
| After 30% tax on interest | ₹12.70 lakh |
| In today's buying power (6% inflation) | ₹9.49 lakh |

*The last bar is below the ₹10 lakh you started with. The balance grew; what it buys shrank.*

**₹10 lakh in a 7% FD, year by year (lakh rupees)**

| Year | Before tax | After 30% tax | After tax, in today's rupees |

| 0 | 10 | 10 | 10 |
| 1 | 10.7 | 10.49 | 9.9 |
| 2 | 11.45 | 11 | 9.79 |
| 3 | 12.25 | 11.54 | 9.69 |

## The same FD for different people

| Tax slab | Effective rate on a 7% FD | Real rate at 6% inflation |
| --- | --- | --- |
| No tax (income below limits) | 7.0% | about +0.9% |
| 20% slab | 5.6% | about −0.4% |
| 30% slab | 4.9% | about −1.0% |

*Real rate = (1 + effective rate) ÷ (1 + inflation) − 1. Slab names are simplified; the new and old regimes differ.*

## So are FDs bad?

No. They are the right tool for money you cannot afford to lose or will need soon: an emergency fund, a down payment due next year, fees due in two years. The mistake is using them for money you will not touch for 15 years and calling it safe.

**Two jobs for money**

| Needed in under 3 years | Needed in 10+ years |
| --- | --- |
| FD is fine | FD alone loses ground |
| Certainty matters more than growth | Tax and inflation compound against you |
| Inflation barely has time to bite | Consider growth assets for part of it |

> **A quick check:** Subtract your tax slab share from the FD rate, then subtract inflation. If the answer is near zero or below, the FD is preserving the number, not the value.

## Frequently asked questions

### Is FD interest taxable?

Yes. FD interest is added to your income and taxed at your slab rate, and banks may deduct TDS above certain limits.

### What is the real return on a 7% FD?

After 30 percent tax the effective rate is 4.9 percent. With 6 percent inflation, the real return is about −1 percent. For someone paying no tax it is about +0.9 percent.

### How much will ₹10 lakh become in a 7% FD in 5 years?

About ₹14.03 lakh with yearly compounding, before tax.

### Are FDs a bad investment?

They are good for short-term goals and emergency money, where safety matters most. For long goals, tax and inflation can leave little or no real gain.

### How do I calculate the real rate of return?

Divide one plus your after-tax rate by one plus the inflation rate, then subtract one. For 4.9 percent and 6 percent that gives about −1 percent.
