Wedding Guest Budget per Guest Calculator

How to use this calculator

1. Enter the project or event values using consistent units.
2. Adjust assumptions to match your scope, vendor quote, or venue plan.

Formula

Usable budget = total budget × (1 − reserve rate). Variable budget per guest = (usable budget − fixed costs) ÷ guest count.

What the result means

The main result is a planning estimate based on your inputs. Supporting figures show the intermediate values so you can identify which assumptions have the largest effect.

Planning tool only. Verify contractual, code, occupancy, pricing, tax, and safety requirements with the appropriate professional or authority.

Example calculation

With a $30,000 budget, $12,000 fixed costs, 120 guests, and a 5% reserve, the variable allowance is $137.50 per guest.

Tips for better results

• Classify costs as fixed or per-person before using the result.
• Keep taxes, service charges, and gratuities inside the applicable budget lines.
• Recalculate after the RSVP deadline using the final attendance estimate.
