School Fees Lifetime Cost Calculator

Updated April 17, 2026 · Modern Life Events · Educational use only ·

Total private school fees across years per child, inflation-adjusted.

Calculate total private school fees across years with annual fee inflation. Enter years of schooling to see total nominal fees over the period.

What this tool does

Private school fees rise faster than general inflation in most markets. Enter current annual fee, years remaining, and expected fee inflation. The tool returns total nominal fees over the period.

25,000 annual fee for 10 years with 5% annual inflation totals roughly 314,400 — not the naive 250,000. Annual fees often compound faster than general inflation, making long-horizon projections without inflation dangerously low.

Per child vs per family

The tool shows one child. For two children starting together, roughly double. For staggered, the total is higher because each child's fees rise year-on-year.

Quick example

With current annual fee of 25,000 and years of schooling of 10 years (plus annual fee inflation of 5%), the result is 314,447.31. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Current Annual Fee, Years of Schooling, and Annual Fee Inflation. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

What's happening under the hood

Geometric sum of annual fees each year, compounded at the inflation rate. Nominal total — not inflation-adjusted for general inflation. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Spreading the cost

Starting earlier always costs less per month than starting late. That's the main lever this tool surfaces. Whatever the total, dividing it by the months until the event gives a monthly target that's easier to build into a budget.

What this doesn't capture

Life events generate side costs the figure doesn't include: time off work, lost income, travel for others, aftercare. Add 10–15% to the direct number as a buffer; the items you haven't thought of usually fill most of it.

Methodology

Frequently Asked Questions

Why include fee inflation?
Because private school fees have historically risen at 4-6%/year above general inflation. Flat-fee projections substantially understate lifetime cost.
What about siblings?
Sibling discounts usually 5-20%. Factor in by reducing effective fee per child. Or run the tool per child separately.
Boarding vs day?
Boarding is typically 2-2.5× day fee. Use the actual fee for your school — big differences.
Extra costs?
Uniform, trips, music lessons, and exam fees can add 15-25% on top of tuition. Plan for annual extras separately.
