> The POMIS calculator works out the monthly interest income from the Post Office Monthly Income Scheme – a 5-year government savings scheme paying interest every month – and the total interest over the term.

## Inputs

- Deposit amount
- Account type
- Interest rate (p.a.) (%)

## Results

- Deposit used (within the limit)
- Monthly income
- Yearly income
- Total interest over 5 years
- Amount returned at maturity

## Formula

```
Monthly income = deposit × rate ÷ 12
Total interest = monthly income × 60
Maximum deposit: ₹9 lakh (single), ₹15 lakh (joint)
```

## Explanation

POMIS pays a fixed rate (7.4% p.a. in recent quarters) for 5 years, after which the principal is returned. Interest is taxable. The rate is reviewed every quarter – check the current rate.

### How to use the Post Office Monthly Income Scheme Calculator

- **Deposit amount**
- **Account type**
- **Interest rate (p.a.)**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the deposit amount, account type and interest rate.

### Tips

- Figures use the latest published rates; government scheme rates are revised every quarter.
- Choose between the old and new tax regimes carefully – deductions only count in the old regime.
- Keep proofs of investments and rent for your employer and the tax return.
- Use the official portal of each scheme for exact maturity values.

### Common mistakes to avoid

- Assuming scheme interest rates are fixed for the whole term.
- Forgetting tax on interest from fixed and recurring deposits.
- Missing the yearly minimum deposit on PPF or Sukanya Samriddhi accounts.
