This calculator vs. Square Appointments
Two different jobs: Square Appointments is an account-based booking and payments platform for running a service business's whole diary. This page is a free, private worksheet for one question — what should the deposit be, and does charging it actually leave you with more money — before that number goes into any booking system's settings.
What each tool is for
Square Appointments is a booking and point-of-sale platform from Block, Inc. (formerly Square, Inc.), founded in 2009 by Jack Dorsey and Jim McKelvey and headquartered in San Francisco. It gives clients a booking page to schedule themselves, syncs calendars and staff schedules, sends automated reminders, and, through Square's own payment processing, can require a card on file or a deposit before a booking is confirmed. It is built for salons, spas, trainers, tutors, photographers, and other service businesses to run their whole client-facing diary and take payment through one account. Square's own pricing page is not reachable from this session to confirm today's plan names or processing rates, so no dollar figure for Square Appointments is invented here: only its well-documented identity and category — an account-based booking and payments platform with deposit and no-show protection features — are stated.
This calculator does none of what Square Appointments does. It has no booking page, no calendar, no client list, and no connection to a payment processor — it stores and charges nothing. It takes one service price, a deposit percentage, bookings per week, an expected booking rate once a deposit is required, and no-show rates with and without a deposit, and turns them into the deposit amount, the balance due at the appointment, the cash a year of deposits secures, a side-by-side of yearly revenue with and without the deposit so you can see whether it actually pays for itself, and a policy paragraph you can paste into whichever booking system you already use. It runs free in any browser, keeps no account, and uploads nothing you type.
| Question | Where to answer it |
|---|---|
| I run a service business and need a booking page, calendar sync, staff scheduling, and payment processing in one account. | Square Appointments, or a comparable platform — running the booking pipeline is not something this calculator does. |
| What deposit percentage should I actually set, and what does it mean in dollars on my service price? | This calculator — free, instant, private, no account. |
| Does requiring a deposit leave me with more money once some customers book elsewhere and fewer no-show? | This calculator's “Does the deposit pay for itself?” panel, not a guess. |
| How do I actually charge the deposit or hold a card at the moment someone books online? | Square Appointments, or your own booking and payment platform — this calculator never touches payment. |
| What should the balance due look like on the day of the appointment? | This calculator — service price minus the deposit, with no processing fee added. |
| How does the math behind an appointment deposit actually work? | This calculator's own worked table at five common percentages. |
| Do I need to create an account or sign up to use the tool? | This calculator: no. Square Appointments is used through a Square account. |
Most service businesses get different value from each: Square Appointments (or a comparable platform) for running client bookings and collecting payment as an ongoing account, and a private calculator like this one for an instant, no-login answer to what the deposit percentage should be and whether it is worth charging at all, before that number is typed into a business system. This page's own figures are a pricing model, not a booking record, a held card, or a processed payment.
This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
Common questions
Should I use this calculator or Square Appointments?
Both, for different jobs, and most service businesses that take deposits end up using something like both. Square Appointments, from Block, Inc. (formerly Square, Inc.), founded in 2009 by Jack Dorsey and Jim McKelvey and headquartered in San Francisco, is a booking and point-of-sale platform: a client-facing booking page, calendar sync, automated reminders, staff and client management, and — through its own connected payment processing — the ability to require a card on file or take a deposit at the time of booking. It is an account-based service you sign up for and run your diary through. This calculator does none of that. It takes one service price, a deposit percentage, weekly bookings, an expected booking rate, and no-show rates with and without a deposit, and turns them into the deposit amount, the balance still due, the cash a year of deposits secures, whether the policy actually leaves you ahead of not charging one at all, and a policy paragraph you can paste into whichever booking system you already use. It runs free in any browser, keeps no account, and uploads nothing you type. A service business that already books clients online, takes payment at booking, and wants the deposit setting enforced automatically is better served by Square Appointments or a comparable platform; a business that wants an honest, private answer to what the deposit percentage should be, and whether it pays for itself, before it is typed into any booking system is in the right place here.
Can Square Appointments collect the deposit this calculator works out?
Yes, once you have decided the number. Square Appointments' own deposit and no-show protection settings are where a deposit or a card on file is actually charged to a client at booking; this calculator does not collect or process any payment. What it does is answer the question that setting asks you to fill in — what percentage, and is it worth requiring at all, given your own no-show rate and how many bookings you expect to keep once one is required. The two are sequential, not competing: work out the number here, then enter it into whichever platform runs your bookings.
Is this page affiliated with Square Appointments?
No. This site is not affiliated with, endorsed by, or sponsored by Block, Inc., Square, or Square Appointments. Square is a trademark of its owner, named here only to describe what this calculator is and is not.
