The formulas
- Cost of year k = cost x (1 + inflation)^(years until start + k)
- Savings grown = saved x (1 + return)^years
- Monthly deposit = shortfall / [((1 + r/12)^(12 x years) - 1) / (r/12)]
How it works
This projects each year of college at its inflated price and adds them. It then grows current savings to the start date and finds the level monthly deposit that closes the gap. It treats the whole bill as needed on day one, which is conservative, since later years can keep earning after enrollment.
Returns and costs are assumptions, not forecasts. Net price after grants and scholarships is lower than sticker price. Whether savings are in a 529 plan or a taxable account changes the after-tax return, which this tool does not model.

Common questions
What inflation should I use?
Use a rate you can defend for your target school type. Check the school's published history of cost increases.
Does it include financial aid?
No. Enter an annual cost net of expected aid if you want it reflected.
Why monthly compounding?
Deposits are monthly, so the return is applied monthly at the annual rate divided by 12.
