Instead of receiving interest in cash, the interest is added to your balance and itself earns interest in the following periods. This creates a compounding effect: each month your deposited money, plus all previously earned interest, works together to generate returns.<\/p>\n<p>This structure is common in recurring deposit schemes offered by banks and in dividend reinvestment plans (DRIPs) for stocks and mutual funds. It appeals to savers who want a disciplined, hands-off approach: you commit to a fixed deposit each period, and reinvestment does the rest. The result is that even modest monthly contributions can grow into a substantial sum over several years.<\/p>\n<p>Because deposits are made at the beginning of each period (an annuity due), each deposit compounds for one extra month compared to an end-of-month deposit. That is why the formula multiplies by \\((1 + r)\\). The interpretation of the result is straightforward: the <strong>Maturity Value<\/strong> is what your account will hold at the end of the term, and the <strong>Total Interest Earned<\/strong> shows how much of that value came from compounding alone.<\/p>\n<h2>Assumptions and Limitations<\/h2>\n<ul>\n<li><strong>Fixed deposits:<\/strong> the calculator assumes you deposit exactly the same amount every month, with no skipped or extra payments.<\/li>\n<li><strong>Fixed rate:<\/strong> the interest rate must remain constant for the entire term. Variable-rate or stepped-rate plans will produce different results.<\/li>\n<li><strong>Monthly compounding:<\/strong> the annual rate is divided by 12 and applied monthly. Plans that compound quarterly or annually will differ slightly.<\/li>\n<li><strong>Deposits at the start of the month:<\/strong> if your deposits occur at the end of each month, remove the \\((1 + r)\\) factor from the formula and the result will be slightly lower.<\/li>\n<li><strong>Taxes and fees:<\/strong> the calculation is gross. Taxes on interest, account fees, or early-withdrawal penalties will reduce the actual maturity value.<\/li>\n<\/ul>\n<p>To compare this plan with a lump-sum alternative, try the <a href=\"https:\/\/wpcalc.com\/en\/finance\/term-deposit\/\">Term Deposit<\/a> or <a href=\"https:\/\/wpcalc.com\/en\/finance\/special-recurring-deposits\/\">Special Recurring Deposit<\/a> calculators.
