How to use the FD calculator
Enter the deposit, annual rate and tenure. Choose Reinvest interest when interest is added back to the deposit, or Periodic payout when interest is transferred out monthly, quarterly, half-yearly or yearly.
Compounding versus periodic payout
Compounding earns interest on earlier interest credits, so more frequent compounding produces a slightly higher maturity for the same quoted annual rate. Periodic payout is different: the interest is withdrawn, so the principal returned at maturity normally remains the original deposit.
| Deposit style | What the calculator does |
|---|---|
| Monthly/quarterly/half-yearly/yearly reinvestment | Uses compound-interest periods |
| Interest at maturity | Uses simple interest unless the product states compounding |
| Periodic payout | Shows regular gross/net payout and total term interest |
Interest tax and bank-specific rules
The default 5% is a convenient resident individual estimate based on the current Tools Pasal interest-TDS reference, but it is editable. Banks can use product-specific day counts, minimum terms, renewal rules and premature-withdrawal penalties. Always compare the result with the bank’s deposit advice.
Why rates are entered manually
Nepal bank rates change frequently and differ by tenure, institution and customer type. A manual rate avoids presenting a stale “live” rate. The calculator itself works offline and keeps financial inputs in your browser.
Frequently asked questions
How is fixed deposit maturity calculated?
For reinvested interest, maturity depends on the principal, annual rate, time and compounding frequency. If interest is paid out instead, the principal normally remains unchanged and withdrawn interest does not compound.
What FD rate should I enter?
Enter the annual fixed-deposit rate offered by your bank or financial institution for the selected tenure. This calculator does not scrape or advertise live bank rates.
Why is tax editable?
The applicable withholding can depend on depositor type and current tax rules. The calculator starts at 5% for a resident natural-person estimate, but lets you replace it with the rate applicable to you.
Does premature withdrawal change the result?
Usually yes. Banks may reduce the rate, charge a penalty or recalculate interest for premature withdrawal. This calculator assumes the deposit runs for the full entered term.
