Should I Send My Kid to Private School? The 9-Number Checklist That Actually Answers the Question
Should I Send My Kid to Private School? The 9-Number Checklist That Actually Answers the Question
Here's the conversation I keep having with friends: someone's kid is about to start kindergarten, the local public school feels uncertain, and they're weighing a $28,000/year private school alternative. They ask me, "Is it worth it?"
And my answer is always the same: I don't know yet. Tell me your nine numbers.
Not because the question is complicated. Because the right answer changes completely depending on your specific situation — and most people make this decision without ever calculating the numbers that actually determine it.
This post is the checklist I walk every friend through before they sign anything.
Why Rules of Thumb Will Wreck You Here
"Private school is worth it if you can afford it." "Buy in a good district and skip the tuition." "Just apply for financial aid." These are the kinds of answers you get when you Google this question, and they're almost useless.
Here's why: the private vs. public school financial decision involves at least a dozen interacting variables that move in opposite directions depending on your family's circumstances. The same $28,000/year private school represents a radically different financial burden — and a radically different value proposition — for a single-child family in a mid-tier public district versus a three-child family in a district where the house premium is already $180,000.
Think of it like meeting with a financial advisor for the first time. According to NerdWallet's guide on what to expect from that first meeting, a good advisor spends most of the session asking about YOUR goals, risk tolerance, family structure, and existing assets before saying a single thing prescriptive. They don't walk in with a recommendation — they build a model around your specific situation.
That's exactly the approach that works here. So let's run through the nine questions.
The 9-Number Checklist
1. What is the actual tuition — and what will it be in year 13?
The number on the brochure is not the number you'll pay. Private school tuition has historically grown at roughly 3–4% annually. The Bureau of Labor Statistics reported CPI at +0.3% in February 2026 (annualizing to approximately 3.6%) — and private school tuition has tracked at or above general inflation for decades.
Worked example: A school charging $28,000 today at 3.5% annual tuition inflation reaches $43,600 by year 13. The 13-year nominal total: approximately $476,000 for one child. Most families are quoting kindergarten tuition and assuming it stays flat. It doesn't.
2. What is your public school alternative's house price premium?
If your zoned public school is weak, you have two real alternatives: private school OR moving into a stronger district. That house premium is a cost, and at today's mortgage rates it's a significant one.
Per the analysis in Private School Tuition vs. School District House Premium: Which Costs More Over 13 Years at Today's 6.7% Mortgage Rates?, a $100,000 house premium financed at 6.7% costs roughly $6,700/year in additional interest alone — and that's before factoring property tax differences. Over 13 years, that can run $87,000–$120,000 in actual cash outflow, depending on your tax situation.
Your number: Pull two comparable homes on Zillow — one in your target district, one in your current or alternative neighborhood. The price gap IS your public school cost, and it needs to be modeled against tuition.
3. Are you eligible for ESA or voucher programs in your state?
This one quietly changes the math for a lot of families. Education Savings Accounts (ESAs) and voucher programs exist in 32+ states as of 2026. Depending on where you live, you might be eligible for $5,000–$10,000 per year, per child, applied toward private school tuition.
Arizona's ESA, for instance, provides roughly $7,000–$8,000/year. If you have two kids and qualify, that's $14,000–$16,000/year offset against tuition — changing a $56,000/year two-child private school bill into a $40,000–$42,000 one.
Your number: Look up your state's program, income caps, and per-student award amount. Then re-run your tuition total with that subtracted.
Zuvelanti automatically factors ESA eligibility into the total cost model based on your state and income — so you're not leaving money on the table because you didn't know to ask.
4. How many children will go through this decision?
This is the most underestimated variable in the entire analysis. Private school doesn't scale linearly — it multiplies. A family with three kids faces 39 child-years of schooling decisions. At $28,000/year per child in private school, that's potentially $1.1 million in nominal tuition before inflation adjustments.
Meanwhile, the house premium for a public district is a one-time cost shared across all children. Three kids in a great-district public school might cost a $120,000 house premium — versus $1.1M in private school tuition. The math flips completely.
| Scenario | 1 Child | 2 Children | 3 Children |
|---|---|---|---|
| Private school (13 yrs, 3.5% inflation) | ~$476K | ~$952K | ~$1.43M |
| District house premium ($120K at 6.7%) | ~$104K | ~$104K | ~$104K |
| ESA offset (2 qualifying children, $7K/yr) | — | -$182K | -$273K |
| Net private advantage/disadvantage | -$372K | -$666K | -$1.05M |
That table isn't saying public school wins — it's saying the number of kids completely changes the answer, and you cannot evaluate this without modeling all of them.
5. What does the college admission probability adjustment actually look like for your child?
Private school proponents often cite improved college admissions outcomes. This is real — but it's not uniform, and it has a dollar value that needs to be weighed against tuition.
The honest framework: selective private schools do produce higher rates of admission to selective colleges. But the marginal improvement depends heavily on your child's starting academic profile and the specific school. A high-performing student in a strong public magnet program may see minimal lift. A student in a weak public school who would thrive at a rigorous private institution may see meaningful benefit — and an elite college scholarship can offset 2–4 years of prior private tuition.
Your number: Don't assume the college outcome. Look at the specific private school's college placement data AND your public alternative's. The gap is your actual probability adjustment.
6. What is your current household income and effective tax rate?
Private school tuition is not tax-deductible at the federal level in most cases (though 529s can now be used for K-12 up to $10,000/year). Your after-tax cost of $28,000 in tuition is $28,000 — it comes from dollars that were already taxed.
The house premium, by contrast, may include mortgage interest deductions (if you itemize) and is an asset that may appreciate. The true cost comparison needs to happen in after-tax dollars.
7. What is the tuition inflation rate at the specific school you're considering?
Not all private schools inflate equally. Regional Catholic schools often run 2–3% annual increases. Elite independent schools have been running 4–5% in many markets. Over 13 years, the difference between 3% and 5% on a $30,000 starting tuition is about $75,000 in total cost.
Ask the admissions office for historical tuition data. Any school that has been operating for 10+ years can provide this. The pattern tells you far more than the current price.
8. What would you do with the tuition money if you didn't pay it?
This is the opportunity cost question, and it's the one most people skip entirely. $28,000/year invested at a conservative 6% real return over 13 years grows to approximately $550,000. That's not an argument against private school — it's a forcing function to be honest about what you're trading.
If the $28,000/year is the delta between private and a no-premium public alternative, and if you would realistically invest that difference, your private school decision needs to clear a very high bar.
9. What does financial aid realistically look like at your target school?
Most private schools have financial aid budgets, and families earning up to $150,000–$200,000 can qualify for meaningful aid at many institutions. But "need-based aid" varies enormously by school endowment. A school with a strong endowment may offer 40–60% tuition reduction. A tuition-dependent school may offer 10–15%.
Your number: Call the financial aid office before applying. Ask the median aid package for a family at your income level. This is not a rude question — it's a normal one.
What the Full Model Looks Like
When you run all nine variables together, the picture gets specific fast. As we've covered in detail in Private School vs Public: The True $600,000 K-12 Cost Comparison, the total cost difference between pathways regularly exceeds $400,000 for a single child — and the direction of that difference is not fixed. It depends entirely on your numbers.
A family with one child, a $60,000 district house premium, no ESA eligibility, and admission to a school with strong financial aid and documented college outcomes might find private school is cheaper on a net 13-year basis.
A family with three kids, a $90,000 district premium, ESA eligibility in Arizona, and strong public school alternatives might find private school costs $900,000 more over the full horizon.
Both of those statements can be true simultaneously — for different families.
This is exactly why Zuvelanti exists: to run these nine variables in combination, with your specific inputs, across your specific time horizon. The spreadsheet to do this manually takes most people 8–12 hours to build correctly. The model does it in minutes.
Before You Sign Anything
The decision to commit to private school is not a one-year decision. It's a 13-year financial commitment with compounding tuition inflation, and it interacts with your housing decisions, your tax situation, how many kids you have, and what state you live in.
The checklist above won't give you the answer — but it will tell you exactly what to calculate. And once you've calculated it, the right choice tends to become obvious.
Run your specific numbers at Zuvelanti before you write the first tuition check — or before you buy into a district you may not need.
