## How to Project Tuition Increases
Tuition typically rises at a rate exceeding general inflation. Projecting future costs helps families plan savings and borrowing.
### Formula
**Future Tuition = Current x (1 + Rate)^Years**
**Total Cost = Sum of tuition each year (geometric series)**
### Historical Context
- Average annual tuition increase: 3-5% for public, 3-4% for private
- Tuition has historically outpaced inflation by 1-2 percentage points
- Total 4-year costs can be 20-30% higher than today's sticker price

Exemplo Resolvido
Current tuition is $15,000 with 4.5% annual increases, projected 4 years ahead.
- Year 1: $15,000 x 1.045 = $15,675
- Year 2: $15,675 x 1.045 = $16,380
- Year 3: $16,380 x 1.045 = $17,117
- Year 4: $17,117 x 1.045 = $17,887
- Total 4-year cost: $15,675 + $16,380 + $17,117 + $17,887 = $67,059
