The value at maturity is the deposit multiplied by 1 plus the APY over 100, raised to the term in years. A \u003Cstrong>10,000 dollar CD\u003C\u002Fstrong> at 4.5 percent APY grows to exactly \u003Cstrong>10,450 dollars\u003C\u002Fstrong> after 12 months, for 450 dollars of interest. Stretch the same deposit to 24 months and the balance reaches 10,920.25 dollars, because the second year earns interest on the first year's interest.\u003C\u002Fp>\u003Ch2>APY versus interest rate\u003C\u002Fh2>\u003Cp>Banks quote two numbers and only one belongs in this calculator. The nominal rate is the raw annual rate before compounding. The \u003Cstrong>APY, or annual percentage yield\u003C\u002Fstrong>, is the effective return with compounding already baked in, and it is the figure US banks must display under \u003Cstrong>Regulation DD\u003C\u002Fstrong>. A CD with a 4.41 percent nominal rate compounded monthly works out to an APY near 4.5 percent. Since the APY already accounts for the compounding schedule, the calculator never asks how often your bank compounds, and the exponent formula reproduces the effective yield whatever the internal schedule.\u003C\u002Fp>\u003Ch2>What common terms earn\u003C\u002Fh2>\u003Cp>The table below runs the formula on a 10,000 dollar deposit at 4.5 percent APY across the usual CD terms. Growth speeds up a little with each added year, and that curve is \u003Cstrong>compounding\u003C\u002Fstrong> at work. It is also why the calculator prints a year by year table once the term passes 12 months.\u003C\u002Fp>\u003Ctable>\u003Cthead>\u003Ctr>\u003Cth>Term\u003C\u002Fth>\u003Cth>Value at maturity\u003C\u002Fth>\u003Cth>Interest earned\u003C\u002Fth>\u003C\u002Ftr>\u003C\u002Fthead>\u003Ctbody>\u003Ctr>\u003Ctd>6 months\u003C\u002Ftd>\u003Ctd>$10,222.52\u003C\u002Ftd>\u003Ctd>$222.52\u003C\u002Ftd>\u003C\u002Ftr>\u003Ctr>\u003Ctd>12 months\u003C\u002Ftd>\u003Ctd>$10,450.00\u003C\u002Ftd>\u003Ctd>$450.00\u003C\u002Ftd>\u003C\u002Ftr>\u003Ctr>\u003Ctd>18 months\u003C\u002Ftd>\u003Ctd>$10,682.54\u003C\u002Ftd>\u003Ctd>$682.54\u003C\u002Ftd>\u003C\u002Ftr>\u003Ctr>\u003Ctd>36 months\u003C\u002Ftd>\u003Ctd>$11,411.66\u003C\u002Ftd>\u003Ctd>$1,411.66\u003C\u002Ftd>\u003C\u002Ftr>\u003Ctr>\u003Ctd>60 months\u003C\u002Ftd>\u003Ctd>$12,461.82\u003C\u002Ftd>\u003Ctd>$2,461.82\u003C\u002Ftd>\u003C\u002Ftr>\u003C\u002Ftbody>\u003C\u002Ftable>\u003Ch2>What the projection assumes\u003C\u002Fh2>\u003Cp>The result assumes you leave the deposit and all the interest in place until maturity.
