Packages and Memberships Calculator

What each session in a course or membership really earns after the discount and the sessions nobody uses, and how much of the cash up front you still owe in treatments.

  • What a course or member session really earns an hour, once the discount, GST, card fees and product are out
  • The deepest discount you can give and still make your target, even if every client uses every session
  • How much of the money paid up front you still owe in treatments, so it never gets spent as profit

How it works

Your numbers in. A decision out.

  1. Buy it

    Pay once by card. The tool opens straight away on the device you paid on, and a link for your other devices lands in your inbox.

  2. Type in your numbers

    It opens with sample numbers so you can see how it works. Type over them with yours.

  3. Read the answer

    Green, amber or red against targets you can change, with what to do about it in plain English.

  4. Run it again

    Rent goes up, minimum wage moves, you hire. Open it and re-run, as often as you like.

Have these handy

What you'll need

  • One treatment's full price, time and product cost
  • Your course: sessions, discount and how many you sell a month
  • Your membership fee and number of members, if you run one
  • Roughly how many prepaid sessions never get used

Good guesses are fine for a first run. You can tighten them later and the answer updates as you type.

Built for here

New Zealand rules, already in

  • GST at 15% worked in for you, with the $60,000 registration line
  • This year's minimum wage, KiwiSaver, ACC and income tax, wherever the tool needs them
  • Holiday pay, public holidays and sick leave counted in any wage it works out
  • Card fees counted on what clients pay

When a rate changes, we update it once and every buyer gets it. See the rates we use.

Does it work on my phone?
Yes. It's a browser tool, not a spreadsheet: no Excel, nothing to install, on a phone, tablet or laptop. Your numbers are saved on that device, so they're there next time you open it. Moving to another device? Use "Download a copy" and open it there. Clearing your browser data deletes saved numbers, so download a copy first.
Do I have to keep paying?
No. You pay once. No subscription, no renewal, and when NZ rates change we update the tool for you. Your tools keep working for as long as we run them online, and if that ever had to end, we'd give you at least 30 days' notice wherever we can. The device you buy on stays signed in for six months; after that, enter your email on My tools and a fresh link arrives in seconds. You never buy a tool twice.
What if I don't know a figure?
It opens with sample numbers, so type over the ones you know and leave the rest for now. A good guess is fine for a first run. The answer updates as you type, so tighten the guesses whenever you find the real figures.
