How It Works
How to Estimate College Costs
Total college cost includes all direct and indirect expenses.
Formula
Total Cost = (Tuition + Room & Board + Books & Fees) x Years
This provides a baseline estimate. Actual costs may increase with inflation, typically 3–5% per year for tuition.
Worked Example
A state university with $15,000 tuition, $12,000 room & board, and $1,500 books/fees for 4 years.
annual_tuition = 15000room_board = 12000books_fees = 1500years = 4
- 01Annual cost = $15,000 + $12,000 + $1,500 = $28,500
- 02Total 4-year cost = $28,500 x 4 = $114,000
- 03Monthly equivalent = $28,500 / 12 = $2,375
