College Cost Calculator

What this college cost calculator does

College costs rise over time, and the bill arrives in a future year when the price may be higher than today's published cost. This calculator projects the annual cost for each year of attendance, adds those years together, applies the share you plan to cover from savings, and estimates the monthly deposit needed to close the gap.

It can start from a common cost preset or from a number you enter. It also accounts for an existing savings balance and the after-tax return on that savings.

How to use this calculator

1. Choose a cost preset or enter today's annual cost.
2. Enter the expected annual cost increase, the number of college years, and how many years remain before college starts.
3. Enter the percentage of the total cost you want to cover from savings.
4. Enter your current savings, the expected investment return, and the tax rate on that return.
5. Click Calculate to see the annual cost projection, total cost, savings target, gap, and monthly saving.

The default example uses a $30,990 annual cost, 5% annual cost growth, a four-year program starting in three years, a 35% savings target, no current savings, a 5% return, and a 25% tax rate on the return.

College cost formulas

After-tax return = Return rate × (1 − Tax rate ÷ 100)
Annual cost in year i = Today's cost × (1 + Cost increase ÷ 100) ^ (Years until start + i)
Total cost = Σ annual cost for each college year
Savings target = Total cost × Savings percent ÷ 100
Current savings future value = Current savings × (1 + After-tax return ÷ 100) ^ Years until start
Gap = max(0, Savings target − Current savings future value)

The monthly saving is the payment that grows to the gap by the time college starts:

Monthly rate = After-tax return ÷ 12
Monthly saving = Gap × Monthly rate ÷ ((1 + Monthly rate) ^ Months − 1)

If the after-tax return is zero, the monthly saving is simply the gap divided by the number of months.

What the results mean

• Annual cost projection: the estimated cost for each college year, starting from today's cost and compounding through the start year. The full table is shown below the result card.
• Total cost: the sum of the annual costs.
• Savings target: the portion of the total cost you plan to fund from savings.
• Current savings future value: what today's savings are expected to grow to by the time college starts.
• Gap: the part of the target not covered by current savings.
• Monthly saving: the amount to set aside each month until college starts, assuming the after-tax return.
• Total contributions and investment growth: how much of the gap comes from deposits and how much from investment growth.

In the default example, the projected total cost is $154,624.87, the 35% savings target is $54,118.70, and the monthly saving is $1,422.67 over 36 months.

Assumptions and limitations

The calculator assumes a constant annual cost increase and a constant after-tax investment return. It assumes deposits are made monthly until college starts and that the savings balance grows at the after-tax return. It does not include scholarships, grants, student loans, work-study, tax credits, or the special tax treatment of 529 plans. It does not model different costs by school, program, housing choice, or year of study.

The presets are broad national averages. Actual costs vary widely by institution and by whether the student lives on or off campus. Use the net price calculator published by a specific school for a more targeted estimate.

Frequently asked questions

Why is the monthly saving higher than the annual cost divided by 12?

The monthly saving covers only the savings target, not the full cost, and it has to grow to that target by the time college starts. If the target is $54,118.70 over three years, the monthly deposit is about $1,422.67 before investment growth. The annual cost is a different number.

How does current savings affect the result?

Current savings reduce the gap because they are projected forward to the college start date. A larger balance or a higher after-tax return lowers the monthly deposit. If the projected balance already exceeds the target, the gap and monthly saving are zero.

Does the calculator include room and board?

The annual cost input is a total annual cost figure. The presets are broad averages, and the calculator does not separately break out tuition, fees, housing, food, books, or travel. Enter a total that matches the cost you want to plan for.

Are 529 plans or education tax benefits included?

No. The calculator applies a single tax rate to the investment return. It does not model 529 tax deferral, qualified withdrawals, the American Opportunity Tax Credit, or the Lifetime Learning Credit. Those features can change the after-tax cost and should be evaluated separately.
