Evening enquiry calculator

What is the wait costing you?

Not our averages — your enquiries, your own trial conversion and your own tuition. We do not tell you what a family is worth on average, because we have not verified that number and you already know yours. The card fee and our own fee are subtracted, because a number that leaves those out is a sales pitch, not a calculation.

Your numbers

Enquiries a month

a month

Everything that comes in asking about classes — the contact form, email, Facebook, the phone. Count last month if you are not sure.

Of those, how many arrive when nobody answers

Evenings, weekends, mid‑class. A parent looks for a school after dinner, once the children are in bed, which is exactly when your front desk is closed.

Of those, how many never come back

Not all of them — most you win anyway when you reply in the morning. This is only the share you lose because they had to wait, and it is the one number here you have to estimate. Set it low and see what is left.

Enquiries that become a booked trial class

Out of everyone who asks, how many actually turn up to try a class. You know this one.

Trials that enroll

Of the children who come to a trial, how many sign up. This is the number most schools already watch.

Monthly tuition

What one child pays you a month. If you have several plans, use the one most of them are on.

How long a family stays

months

Long enough matters more than anything else here. If you do not know, use twelve — it is easier to defend than a guess in either direction.

What is in the number

Every assumption, written down

A calculator that hides its assumptions can produce whatever number it likes. Here are ours, including the ones that work against us.

What we subtract

Our own fee comes off the total

The setup fee lands in the first year and the subscription in every year. Both are taken off before we call anything a gain. The card fee is there too — it goes to Stripe, never to us. If what is left is negative, the page says so in plain words.

What we refuse to assume

We do not tell you what a no-show is worth

You will see figures quoted around this industry — so much lost per instructor per day. We have not verified any of them, so we are not going to build your decision on one. Every number above is yours, and the only thing we compute is the consequence.

What we do not count

No made-up upside

No extra students because the website looks better, no higher prices, no “SEO uplift”. Only two things move: enquiries that can book instead of waiting, and lessons a reminder saves. If the site brings more than that — and it usually brings some — that is on top and not in this number.

Where it is conservative

A recovered lesson is counted once

A student who books a first lesson because they could do it at 10pm usually buys more than one. We count the first and stop. Packages, repeat lessons and the road-test rental are all real and none of them are in here.

Not tax advice and not an offer. Sales tax and any state licence cost are left out, because they are the same either way. The domain (about $12 a year) is paid by you to the registrar. Prices are in US dollars.
