Savings Goal Calculator

How to use this calculator

Enter the amount you want to reach, the amount you have already saved, the number of years you have, and the annual interest rate your savings earn. The calculator finds the monthly deposit that gets you to the goal and shows how much of the target comes from your own money versus interest.

Try a few timelines. Giving yourself more time lowers the monthly amount, and even a modest interest rate does part of the work for you. If the monthly figure feels out of reach, extending the deadline or trimming the goal are the two most direct levers.

How saving toward a goal works

Reaching a savings target has three moving parts: the money you already have, the deposits you add each month, and the interest earned on both. For short and medium-term goals, the deposits usually do most of the work and interest helps at the margin. The longer the timeline, the more interest contributes.

Where you keep the money matters. Money you will need within a few years generally belongs somewhere safe and easy to reach, such as a high-yield savings account, a money market account, or a certificate of deposit, rather than in investments that can fall in value right before you need them. For goals many years away, see Investing for Beginners to weigh the trade-off between higher potential returns and the risk of loss.

How the numbers are calculated

Your current savings grow at the annual interest rate, compounded monthly, over the time you enter. The calculator then works out the monthly deposit whose future value, added at the end of each month and compounded for the remaining time, closes the gap between that grown balance and your goal. The breakdown splits the goal into the amount you already saved, your total deposits, and the interest earned. If your current savings will grow past the goal on their own, the monthly amount needed is zero.

Assumptions

• The interest rate is the same for the whole period. Real savings rates change over time.
• Deposits are made at the end of every month, without interruption.
• Interest is compounded monthly.
• No taxes are deducted; interest earned on savings is often taxable.
• Results are shown in nominal dollars and are not adjusted for inflation.
• Figures are rounded to whole dollars.

Limitations

• This is an educational estimate, not a prediction, guarantee, or individualized advice.
• Savings account rates can change at any time, which would change the deposit needed.
• If you use investments to pursue a goal, returns are not guaranteed and the balance can fall, including below what you put in.
• It does not model taxes on interest or the effect of inflation on what your goal will buy.
• It assumes steady, uninterrupted saving, which real budgets do not always allow.

Frequently asked questions

What interest rate should I use?

Use the yield you can realistically earn on where the money will sit. For a goal within a few years, that is typically a high-yield savings account, money market account, or CD rate. Using a high investment return for a short-term goal is optimistic and ignores the risk that the balance could drop before your deadline.

What if the calculator shows zero per month?

That means the amount you have already saved will grow to your goal on its own within the time you set, so no additional monthly deposit is required under these assumptions. You could reach the goal sooner or aim higher.

Should I keep goal savings in the stock market?

It depends on the timeline. Money needed soon is usually kept in safer, liquid accounts so a market drop cannot derail the goal. Money for goals far in the future may be invested for higher potential growth, accepting that its value will rise and fall along the way.

Does it account for taxes or inflation?

No. Results are in today’s nominal dollars, and interest earned on savings is often taxable. A goal set far in the future will also buy less then than the same number would today.
