Estimates only. Assumptions are listed below, and you can change every input.

Catering proposals almost always show a per-person price that is not what you will pay. A service charge is added on top, sales tax is added on top of that, and in many places the tax applies to the service charge too. Two caterers quoting the same menu price can land thousands of dollars apart once the fine print is applied, and the difference rarely shows up until the final invoice.

This calculator applies the service charge to your food and bar subtotal, then applies sales tax to either the subtotal alone or the subtotal plus service charge, depending on how your state and caterer treat it. It reports the charge, the tax, the all-in total and the true cost per guest. It does not assume any percentage for you; the rates come from your proposal and your state.

How to use this tool

Enter the guest count and the per-person food and bar prices from the proposal.
Type in the service charge percentage and your venue location sales tax rate.
Choose whether the service charge is taxable, then compare the all-in total and true cost per guest across caterers.

What the math assumes

The service charge is applied to the full food and bar subtotal at one flat percentage.
Sales tax is applied either to the subtotal alone or to the subtotal plus service charge, based on your selection; the tool does not know your state rules.
The default 20% service charge and 7% tax rate are placeholders to show the math, not typical rates; use the figures from your proposal and local tax authority.
Voluntary gratuity for staff, cake cutting fees, corkage, rentals and staffing line items are not included unless you fold them into the per-guest prices.
Every guest is charged the same food and bar price, with no reduced rates for children or vendors.

Frequently asked questions

Is the service charge the same as a tip?

Usually not. A mandatory service charge is revenue the caterer keeps to cover staffing and overhead, and only part of it, if any, reaches the servers. Ask directly whether gratuity is included or expected on top.

Why does the tax amount change when I flip the service charge switch?

When the service charge is taxable, the tax base grows by the amount of the charge. On a large invoice that can add several hundred dollars, which is why the tool makes it an explicit choice.

What if my caterer quotes one bundled price per person?

Put the bundled figure in the food field and set the bar field to 0. The service charge and tax will still be applied to the full subtotal.
