Savings Goal Calculator

Last updated July 2, 2026

A savings goal calculator answers the question most people have about saving but rarely model explicitly: given a target amount and a target date, how much do I need to save each month? The formula is simply the future value of an annuity run in reverse — dividing the gap between current savings and the target by the number of months remaining, adjusted for interest earned on the accumulating balance. A person who wants $15,000 in savings in 36 months, currently has $3,000, and earns 4.5 percent in a high-yield savings account needs to contribute approximately $326 per month to reach the goal. Without the interest component — just dividing the remaining $12,000 by 36 months — the number is $333, a difference of $7 per month that illustrates how interest earnings meaningfully matter for savings calculations even at modest rates.

The savings goal framework is useful for almost every financial target: emergency fund completion, down payment accumulation, vacation funding, and major purchase planning. The most important insight the calculator provides is the relationship between time horizon and required monthly contribution — compressing the timeline by six months substantially increases the required monthly amount, while extending it by six months substantially reduces it. For households that feel unable to hit a savings target, the calculator reveals whether extending the timeline is a viable solution or whether the target itself needs to be adjusted.

Modeling your savings goal with the full three-variable framework: target amount, monthly contribution, and expected return. See the monthly contribution required to reach your target on your timeline. If that number exceeds your available savings capacity, the calculator tells you whether extending the timeline, reducing the target, or increasing income is the path to a feasible plan.
