Savings Goal Calculator

Work out how much to set aside each month to hit a savings target, accounting for investment growth.

How the Math Works

The Savings Goal Calculator uses the future value of an annuity formula to determine the monthly deposit required to reach a target savings amount. The formula PMT = (FV - PV(1+r)^n) * r / ((1+r)^n - 1) accounts for compound interest, where FV is the future value, PV is the present value, r is the periodic interest rate, and n is the total number of compounding periods. It first calculates the future value of existing savings (PV) with compound growth, then determines the regular payment (PMT) needed to bridge the gap between that growth and the target amount (FV), adjusted for the time value of money through the interest rate (r).

Practical Applications

To apply this calculation, input your current savings (PV), desired future amount (FV), expected annual interest rate (converted to a monthly rate by dividing by 12), and the number of months (n) until your goal date. For example, saving $10,000 in 3 years with a 5% annual return and $2,000 already saved would require monthly deposits of approximately $215. This tool helps transform abstract financial goals into concrete, actionable monthly targets by factoring in realistic investment returns and existing savings growth.

Day-to-Day Use

This calculator simplifies everyday financial planning by converting long-term savings goals into manageable monthly contributions, reducing the mental burden of incremental progress tracking. Whether saving for a vacation, emergency fund, or major purchase, users gain clarity on how much to set aside regularly, making budgeting more precise and achievable. It also empowers proactive adjustments—like extending timelines for higher monthly amounts—helping individuals align savings with current cash flow constraints and avoid overcommitting to unrealistic targets.

Worked example

Goal $50,000, $5,000 now, 5 years, 4% return → about $703/month.
