Your total contributions are $200 \\(\\times\\) 120 = <strong>$24,000.00<\/strong>, so the interest earned is <strong>$8,775.87<\/strong>.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to Use the Calculator<\/h2>\n<ol>\n<li>Enter the <strong>Monthly contribution<\/strong> \u2014 the amount you plan to deposit every month.<\/li>\n<li>Enter the <strong>Annual interest rate<\/strong> \u2014 the yearly return you expect, as a percentage (e.g. 6 for 6%). You can use decimals such as 5.25.<\/li>\n<li>Enter the <strong>Investment period<\/strong> in years \u2014 how long you will keep contributing.<\/li>\n<li>Read the results: <strong>Future Value of Savings<\/strong> (the final balance), <strong>Total Contributions<\/strong> (the money you put in), and <strong>Interest Earned<\/strong> (the difference, i.e. the growth your money generated).<\/li>\n<\/ol>\n<h2>What Is Compound Savings Growth?<\/h2>\n<p>When you save a fixed amount every month and the account earns interest, two forces work together. First, your own contributions steadily add to the balance. Second, the interest you earn starts earning interest itself \u2014 this is compounding. Over time, compounding contributes an increasingly large share of the total growth, which is why even modest monthly amounts can grow into substantial sums over decades.<\/p>\n<p>The results show three numbers, and each tells you something different. <strong>Total Contributions<\/strong> is the money you could have spent instead \u2014 your own effort. <strong>Interest Earned<\/strong> is what the account gave you for free, purely for letting the money sit and compound. <strong>Future Value of Savings<\/strong> is the sum of both: the amount you would have at the end of the period.<\/p>\n<p>Notice how sensitive the result is to the interest rate and the time horizon. In the example above, 6% for 10 years turns $24,000 of contributions into roughly $32,776. Stretch the same plan to 20 years and the interest portion grows disproportionately, because the later years compound on a much larger balance. This is why financial planners emphasize starting early: time in the market is often more powerful than the size of individual deposits.<\/p>\n<p>This calculator is useful for retirement planning, building an emergency fund, saving for a house deposit, a child's education, or comparing savings accounts and recurring-deposit products with different rates. If you are evaluating whether an investment's returns justify its risk, you may also find our <a href=\"https:\/\/wpcalc.com\/en\/finance\/sharpe-ratio\/\">Sharpe Ratio calculator<\/a> and the <a href=\"https:\/\/wpcalc.com\/en\/finance\/return-on-capital-employed\/\">Return on Capital Employed calculator<\/a> helpful for assessing performance.<\/p>\n<h2>Assumptions and Limitations<\/h2>\n<ul>\n<li><strong>Contributions are made at the end of each month<\/strong> (an ordinary annuity). If you deposit at the start of the month, the actual balance will be slightly higher.<\/li>\n<li><strong>Interest compounds monthly<\/strong> at one-twelfth of the annual rate. Products that compound daily or annually will give slightly different results.<\/li>\n<li><strong>The rate is assumed constant.<\/strong> Real investments (stocks, funds) fluctuate year to year; treat the result as a projection, not a guarantee. A 6% average is a common long-term assumption for diversified portfolios, but returns are never smooth.<\/li>\n<li><strong>No taxes, fees, or inflation are included.<\/strong> Management fees, account fees, and taxes on interest reduce the final balance. To compare contributions in today's purchasing power, discount the result by expected inflation.<\/li>\n<li><strong>No initial balance.<\/strong> The calculator starts from zero. If you already have savings, compute their growth separately (a lump-sum compound interest calculation) and add it to the result.<\/li>\n<li><strong>No withdrawals or skipped months.<\/strong> Every contribution is assumed to be made on schedule for the whole period.<\/li>\n<\/ul>\n<h2>Reference: Growth of $200\/Month at Different Rates and Horizons<\/h2>\n<table>\n<thead>\n<tr>\n<th>Annual rate<\/th>\n<th>10 years<\/th>\n<th>20 years<\/th>\n<th>30 years<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>3%<\/td>\n<td>$27,925<\/td>\n<td>$65,645<\/td>\n<td>$116,547<\/td>\n<\/tr>\n<tr>\n<td>6%<\/td>\n<td>$32,776<\/td>\n<td>$92,408<\/td>\n<td>$200,903<\/td>\n<\/tr>\n<tr>\n<td>9%<\/td>\n<td>$38,713<\/td>\n<td>$133,277<\/td>\n<td>$366,148<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Total contributions for comparison: $24,000 over 10 years, $48,000 over 20 years, and $72,000 over 30 years.
