About this calculator
A savings goal calculator projects the future value of regular deposits, showing how much a habit of saving a fixed amount each month or year can grow into over time. It models the combined power of consistent contributions and compound growth, helping you plan for goals like a down payment, an emergency fund, education, or retirement.
The tool uses the future value of an ordinary annuity formula, FV = PMT × ((1 + r)^N − 1) ÷ r, where PMT is your regular deposit, r is the periodic interest rate (annual rate ÷ number of periods per year), and N is the total number of deposits. Each contribution earns interest from the moment it is made, so earlier deposits compound longer and contribute more to the final balance.
To use it, enter your recurring deposit amount, the annual interest rate you expect, the deposit frequency (usually monthly), and the number of years you plan to save. The calculator returns the projected future value alongside, in practice, the total you actually deposited, so you can see how much of the balance is your own money versus earned interest.
Interpret the future value as your goal balance and compare it to the sum of deposits to see how hard your money worked. Over long horizons, interest can rival or exceed your total contributions. If the projection falls short of your target, increase the deposit, extend the time, or seek a higher return to close the gap.
A key limitation is that the projected rate is assumed constant, while real investment returns fluctuate and savings rates change. The figure also ignores taxes and inflation, so the real purchasing power will be lower. Use it as a planning guide, and revisit it periodically as your contributions or expected returns change.
Frequently asked questions
This calculator assumes you add a fixed amount on a regular schedule, so each deposit compounds for a different length of time. A lump-sum or compound interest calculator grows a single initial amount. Use this one when you save steadily rather than investing all at once.
It uses the ordinary annuity method, where deposits are made at the end of each period. If you contribute at the start of each period instead, the balance would be slightly higher because every deposit compounds for one extra period.
Compare the future value to your total deposits. For example, saving $200 a month at 6% for 10 years grows to about $32,776 while you deposited only $24,000, meaning roughly $8,776 came from interest. Longer horizons tilt the balance even more toward interest.
Use a realistic, conservative figure based on where you save. A high-yield savings account might return a few percent, while a diversified long-term investment portfolio might average more but with risk. Avoid optimistic rates, since overestimating return inflates the projection.
Yes. The projected balance is in today's nominal dollars and ignores inflation, which erodes purchasing power over time. To plan in real terms, either target a higher goal or subtract an inflation estimate from your assumed return before calculating.
Raising your deposit boosts the future value significantly, especially if you do it early when contributions have the most time to compound. This tool assumes a constant deposit, so recalculate whenever your contribution changes to keep the projection accurate.
