Savings Goal Calculator: How Much to Save Each Month
Short answer: a savings goal calculator works out the monthly amount needed to reach a target by a date. Divide the goal by the number of months for the simple answer, such as $10,000 in three years is $278 a month. Interest lowers it: at an assumed 4% the same goal takes about $262 a month. Enter your own amount, date and free monthly money in the Goal check to see whether it fits.
Key takeaways
- Without interest, monthly saving = goal divided by months. With interest, the monthly amount is a little lower.
- Longer timelines cost much less per month. Doubling the time roughly halves the amount.
- Check your goal against the money you have free, not just the arithmetic. A goal that does not fit needs a later date or a smaller amount.
- For short goals, interest matters little. For goals ten years out, it does more of the work.
How do you calculate a savings goal?
With no interest: monthly amount = goal divided by months. With interest at a yearly rate, using a monthly rate r (yearly rate divided by 12) and n months of deposits at the end of each month:
monthly amount = goal × r ÷ ((1 + r)n − 1)
For $10,000 in 36 months with no interest, that is $278. At 4% a year, r is 0.00333 and the monthly amount is $262. The difference is small over three years and bigger over ten.
How much do you need to save each month?
The table shows monthly amounts for common goals and time frames, in a savings account earning an assumed 4%:
| Goal | 1 year | 3 years | 5 years | 10 years |
|---|---|---|---|---|
| $5,000 | $409 | $131 | $75 | $34 |
| $10,000 | $818 | $262 | $151 | $68 |
| $25,000 | $2,045 | $655 | $377 | $170 |
| $50,000 | $4,091 | $1,310 | $754 | $340 |
| $100,000 | $8,182 | $2,619 | $1,508 | $679 |
With no interest, the same goals need more: $10,000 in three years is $278, in five years $167 and in ten years $83. The gap grows with time, which is why a ten-year goal gets help from interest. Rates change, so use a figure that matches your account.
How do you know if the goal fits?
- Find your free money. Take-home pay minus essential costs and other commitments. See how to make a budget.
- Compare. If the monthly amount is within your free money, the goal fits. If not, it does not fit as stated.
- Adjust one lever: push the date out, lower the target, raise your free money, or start with a lump sum.
The free Goal check does these steps for you and gives a verdict: it fits, it fits with little room, or it does not fit, with options such as the date that would work.
What mistakes distort a savings goal?
- Ignoring inflation. A goal with a price tag today, such as a car or tuition, usually costs more by the date. Add a margin for long goals.
- Counting interest that is not there. Rates change, so use a cautious figure and recheck.
- Forgetting taxes and fees on interest or investments.
- Setting a date with no slack. Add a month or two for surprises.
- Mixing goals in one account, so no one can see progress.
What is a realistic order for several goals?
Most people have more than one goal and one pool of free money. A common order is a starter emergency fund, any employer retirement match, high-interest debt, then the rest by date and importance. See how to save for multiple goals and financial goals examples.
Where can the money for a goal be kept?
- Under three years: a high-yield savings account, CDs or Treasury bills. See savings accounts, CDs and Treasury bills compared.
- Three to ten years: a mix of cash and bonds, and some stock funds for goals toward the end.
- Ten years or more: diversified stock index funds, such as for retirement. See how to invest $10,000.
Keep each goal in its own labelled account, or a sinking fund, so the money is not spent on something else. See sinking funds.
