Most FD calculators stop at maturity. This one shows the year-wise interest the bank will report, the TDS it will deduct, and what you keep at your slab.
Maturity amount
| Total interest earned | |
| TDS the bank will deduct (approx., over tenure) | |
| Income tax on interest at your slab (incl. 4% cess) | |
| Post-tax interest you keep | |
| Effective post-tax annual return |
| Year | Opening | Interest accrued | Closing | TDS (10%) |

Cumulative FDs in most banks compound quarterly: maturity = P × (1 + r/4)^(4n). ₹1 lakh at 7% for 5 years becomes about ₹1,41,478. Non-cumulative FDs pay simple interest out every month or quarter.
When interest from that bank crosses ₹50,000 in a financial year (₹1,00,000 for senior citizens), at 10% — 20% without PAN. Submit Form 15G/15H in April if your total income is below the taxable limit.
Every year on accrual, at your slab. The bank reports accrued interest in your AIS annually; declaring it only at maturity creates a mismatch and can push the maturity year into a higher slab.
For income within the ₹12 lakh new-regime rebate, FD interest is effectively tax-free and simple. At the 30% slab, the post-tax return is under 5%; compare with the RD calculator for monthly savings and PPF for 15-year tax-free compounding.
The ITR wizard pulls AIS interest and compares both regimes.
