When the monthly contribution is fixed, the time frame may be the most useful number. That way you can set a realistic date before committing to a purchase.
An example with numbers
You need $3,000 and have $750. At $150 a month, 15 contributions are missing, with no interest. If you skip a month and then return to the same pace, you will need one more month.
Try it with your numbers
Select “How long will it take”. Compare $150 with $175 a month and see how many full contributions each option needs.
