How accurate is this calculator?
This calculator computes the monthly savings amount required to reach your goal using compound-interest math. If you select "Years," it compounds annually; if you select "Months," it compounds monthly. The current savings balance grows at the same rate over the time horizon, and the calculator solves for the additional monthly contribution needed to fill the remaining gap. Real account growth depends on your bank's actual APY, which can change over time. Use this for goal-setting and adjust as your account terms change.
