Formula Used

The calculation uses the future value formula for compound interest:

FV = P × (1 + r/n)^nt
Where:
FV = Future Value (college cost)
P = Monthly savings amount (what we're calculating)
r = Annual interest rate (as a decimal)
n = Number of times interest is compounded per year (12 for monthly)
t = Number of years until college

We rearrange the formula to solve for P (monthly savings):

P = FV / (1 + r/n)^nt

Worked Example

Let's say you expect to pay $50,000 for college in 18 years, and you have a high interest savings account with a 5% annual interest rate compounded monthly.

Using the formula:

P = $50,000 / (1 + 0.05/12)^12×18
P = $50,000 / (1 + 0.004167)²¹⁶
P ≈ $50,000 / 3.42
P ≈ $14,620.66

You would need to save approximately $14,620.66 per month to reach your $50,000 college savings goal in 18 years with a 5% annual interest rate.
