How FD & RD Interest is Calculated
Compound Interest, Compounded Quarterly
A fixed deposit grows a single lump sum, while a recurring deposit grows a stream of monthly deposits. Indian banks compound the interest quarterly:
where P = principal, r = annual rate (decimal)
RD: Maturity = R ร [(1+i)^N โ 1] / [1 โ (1+i)^(โ1/3)]
where R = monthly deposit, i = r/4, N = number of quarters
FD & RD โ Taxation & TDS Rules
1. FD vs RD โ What's the Difference?
A Fixed Deposit is a one-time lump-sum investment locked in for a chosen tenure. A Recurring Deposit lets you deposit a fixed amount every month, ideal for building savings from regular income. Both offer assured, fixed returns unaffected by market movements.
2. TDS on Interest (Section 194A)
- Banks deduct TDS at 10% on interest once it crosses โน50,000 in a financial year (raised from โน40,000 by Budget 2025).
- For senior citizens (60+), the threshold is โน1,00,000 a year.
- If you don't provide your PAN, TDS is deducted at 20%.
- TDS is only advance tax โ you can claim it back in your ITR if your total tax is lower.
3. Avoiding TDS with Form 15G / 15H
If your total income is below the taxable limit, submit Form 15G (below 60) or Form 15H (senior citizens) to your bank at the start of the year. The bank will then not deduct TDS on your interest.
4. Important Points
- TDS being deducted doesn't mean interest is tax-free โ you must still add the full interest to your income and pay tax as per your slab, taking credit for the TDS.
- Interest is taxed on an accrual basis each year, even for a multi-year FD where interest is paid only at maturity.
- A 5-year tax-saver FD qualifies for Section 80C deduction, but its interest is still taxable.
Step-by-Step Calculation Example
Consider Rohan, who opens a fixed deposit:
- Principal: โน1,00,000
- Interest rate: 7% per year
- Tenure: 5 years (60 months)
- Compounding: Quarterly
How the Maturity is Worked Out:
- Quarterly rate: 7% รท 4 = 1.75% per quarter.
- Number of quarters: 5 years ร 4 = 20.
- Maturity: โน1,00,000 ร (1.0175)ยฒโฐ โ โน1,41,478.
- Total interest: โน1,41,478 โ โน1,00,000 = โน41,478.
On TDS: Rohan's interest is about โน8,300 per year โ below the โน50,000 threshold โ so no TDS is deducted. He must still declare the interest and pay tax at his slab rate each year.
