How to use it

Enter current annual college cost, education inflation, child age, college start age, years in school, current savings, and expected return using a school-cost estimate you can defend. Tuition inflation has often run near 5%, which is higher than general CPI.
Read years until college, projected annual cost at enrollment, projected total college cost, and the monthly savings needed. As the time horizon gets shorter, the monthly contribution required becomes much less sensitive to the return assumption.
If the monthly amount needed is too high, you likely need some mix of a lower target school cost, more years until enrollment, scholarships, or a larger family contribution later. Hoping for higher returns is not a strategy.
Set an automatic 529 or education-account contribution at the required monthly level and revisit school-cost assumptions early, not when applications start. Use the compound interest calculator to stress-test a more conservative return.
Re-run yearly, after large market moves, or when the school target changes. Track funded percentage, monthly contribution needed, and years remaining until enrollment.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask

Why does the tool use 5% for education inflation?

College costs have historically increased at roughly 4–6% per year — well above general CPI inflation. Using 5% as a default gives a realistic projection; adjust it up or down based on your target school type.

What is a 529 plan and should I use one?

A 529 is a US tax-advantaged education savings account where investment growth and qualified withdrawals are tax-free. This calculator is account-agnostic — it works for 529s, custodial accounts, or any investment vehicle. Consult a tax adviser about the best account type for your situation.

What if I start saving late?

The tool will show a higher required monthly contribution. If the number is too large, consider reducing your goal (e.g., covering 2 years instead of 4), entering a lump sum contribution, or accepting that loans may cover part of the cost.

Does 'annual college cost' include room and board?

Yes, if you include it. Enter the total annual cost of attendance (tuition + fees + room + board + other) for a more accurate projection. The average total cost for a 4-year university in the US is $30,000–$60,000/year depending on public vs. private.

What investment return rate should I use?

Early on (10+ years away), 6–8% is reasonable for a diversified stock portfolio. As college approaches, most advisers recommend shifting to more conservative holdings, which lowers expected return to 3–5%. The tool uses a single blended rate — conservative assumptions protect against shortfalls.
