How much should a private school spend on marketing?

Why the percentage rules fail

The usual advice is to spend some percentage of the operating budget on marketing, and the figure quoted for schools ranges from one to five percent depending on who's selling what. The problem is that two schools of identical size can have opposite needs. One has a waitlist in eight of ten grades and should spend almost nothing on recruiting new families. The other has forty open seats across three grades and would be underspending at five percent. A percentage tells you what you can afford. It doesn't tell you what the job costs.

The better question is how many families you need to enroll, what it takes to enroll one, and what each step of that costs. That turns marketing from an expense line into a plan with a number you can defend to a board.

Start from open seats

Count the seats you need to fill by grade for next fall, after expected attrition and graduation. Then look at last year's funnel: how many inquiries it took to produce one enrolled family. If you don't have that number, use the admissions software's history or the admissions director's best estimate and resolve to track it properly from now on. At many private schools somewhere between one in four and one in eight inquiries enrolls, with the schools that answer quickly and tour well at the better end of that range.

Multiply open seats by inquiries per enrollment and you have the number of inquiries the year has to produce. Some of those will arrive on their own, from referrals, search and the school's reputation. Last year's source data tells you how many. The gap between what arrives on its own and what you need is what the paid part of the budget has to buy.

A worked example

Say a PreK through 8 school needs to fill fifteen seats, mostly in kindergarten and sixth grade. Last year one in six inquiries enrolled, so it needs about ninety inquiries. Referrals and organic search produced fifty last year, which leaves forty to buy. Multiply forty by the cost per inquiry from the school's own search campaign (or from a first ninety-day test if it has never run one), concentrate that spending in the admissions season, add the landing pages, the photography those pages need, and the time someone spends answering inquiries the same day, and the school has a real budget built from its own numbers rather than a percentage borrowed from someone else's.

Run the same math with the inquiry-to-enrollment rate improved to one in four, which is what better follow-up and a stronger tour tend to produce, and the school needs sixty inquiries instead of ninety. That's the point most budget conversations miss: the cheapest marketing dollar is the one you don't need because the admissions process got better.

Where the money should go

In rough order of return for a school with open seats: the website pages that answer what parents search for, by program, grade band and town, because every other channel sends people there; a complete and active Google Business Profile and reviews on the sites parents read, which cost time more than money; Google Search ads aimed at the specific grades with open seats; photography and short video of real classrooms, which every page, ad and post draws on for a year; Meta ads for open houses and events; and the admissions team's capacity to respond quickly, which is a staffing decision that belongs in the marketing conversation.

Things that rarely earn their keep for schools: billboards, general brand campaigns, printed magazines, sponsorships bought for visibility rather than relationships, and any tool that promises inquiries without a plan for who answers them.

Fixed costs and seasonal costs

Separate the budget into what runs all year and what runs in season. The website, profiles, reviews, photography and the admissions CRM are fixed and modest once built. Paid advertising should rise and fall with the calendar: heaviest from January through March when most families decide for fall, a second push in late summer for families who moved or changed their minds, and a lower steady level otherwise so the school stays visible to the parent who starts looking in October. Spending the same amount every month is the most common way schools overspend in June and underspend in February.

What a full school should spend

A school with waitlists still needs marketing, just a different kind. Its budget shifts to retention and reputation: the re-enrollment communication that keeps families from drifting, the referral asks that keep the waitlist deep, the reviews and search presence that keep the school the obvious choice in its town, and the content that lets the school open a new section or a new entry point when it decides to grow. Paid advertising can drop to a small brand campaign that protects the school's own name in search. Cutting to zero is a mistake, because the waitlist is the result of visibility built over years, and it thins quietly when the visibility stops.

Mistakes that waste a budget

Buying inquiries before fixing follow-up, so more families inquire and the same share goes unanswered. Measuring clicks, impressions or website visits instead of tours and enrollments by grade. Spreading a small budget across six channels so none of them gets enough to work. Cutting advertising in the slow months, which is when it's cheapest and when the few families searching are the most serious. And advertising the school in general when the open seats are in one grade, which fills the inbox with families for the grades that are already full.

Deciding the number

Write down open seats by grade, last year's inquiries by source, and last year's inquiry-to-enrollment rate. Build the inquiry target, subtract what arrives on its own, and price the gap at a realistic cost per inquiry. Add the fixed pieces that aren't in place yet. Present that to the board as a plan with a projected cost per enrolled family, next to what one family pays in tuition over the years they stay. That conversation goes very differently from one about percentages.
