What if I save $100 every month?
See what $100 a month adds up to over the years — as plain savings, or with a growth rate you choose.
After 10 years you would have
$12,000
- You put in
- $12,000
- Saved in the first year
- $1,200
Year by year
| Year | Total saved |
|---|---|
| 1 | $1,200 |
| 2 | $2,400 |
| 3 | $3,600 |
| 4 | $4,800 |
| 5 | $6,000 |
| 10 | $12,000 |
Assumptions behind this result
- You save $100 every month, added at the end of each month.
- No interest or investment growth — just the money you put away.
- Inflation, taxes and fees are not taken into account.
Saving a fixed amount every month is the simplest plan there is, and the total is worth seeing once the years are added up. Set the amount, how often and for how long — and, if you like, a yearly growth rate to see what interest or investing could add.
Growth is an assumption you choose, not a promise: leave it at 0% to see only the money you put away.
How it is worked out
Every period, your balance first grows by the period's share of the yearly rate, then your saving is added. With growth set to 0, the total is simply your saving multiplied by the number of periods.
A yearly rate is turned into a rate per period that compounds back to the same yearly figure — 6% a year becomes about 0.487% a month, not 0.5% — so changing how often you save does not change the yearly return.
If you raise your saving each year, the new amount applies from the first period of the following year.
