Recurring deposit (RD) calculator

This calculator uses the accepted simple-interest RD formula M = D·n + D·n·(n+1)/2·(r/1200), where D is the monthly deposit, n is the number of monthly instalments and r is the annual interest rate in percent. The first term is everything you pay in (D·n) and the second term is the interest, since each instalment earns interest for the number of months it remains on deposit.

A recurring deposit lets you pay a fixed amount into the account every month for a chosen tenure, earning a fixed interest rate on the growing balance. A fixed deposit takes one lump sum at the start. RDs suit savers building a habit out of regular income, while FDs suit money you already have in hand.

RD rates in Nepal move with the wider deposit-rate environment and differ by bank and tenure — in recent years they have commonly sat in the high single digits to low double digits per year. Nepal Rastra Bank publishes the prevailing interest-rate ranges. Always check your bank's current published rate before relying on a figure.

Interest credited by a resident bank is generally subject to tax deducted at source (TDS) under the Income Tax Act. The applicable rate is set by the Finance Act and collected by the Inland Revenue Department. Enter your TDS percentage in the optional field to see the maturity value net of tax; confirm the exact rate that applies to your account.

Banks may compound interest (often quarterly) rather than use the straight simple-interest formula, may round instalments and interest differently, and may apply or exempt TDS in their own way. This tool is a planning estimate; treat your bank's official maturity statement as the authoritative figure.

Yes. Enter the tenure in months — for example 12 for one year, 60 for five years or 120 for ten years. The maturity and interest update instantly as you change the monthly deposit, rate or tenure.
