Overview

This tool helps you tally all your event-related expenses—venue, catering, decor, entertainment, etc.—and optionally apply a tax or service-fee percentage to get a comprehensive budget forecast.

How It Works

We sum each individual expense, compute any additional charges (tax/fee), then present a detailed breakdown and grand total.

Formula: $$ \text{Total Cost} = \sum \text{Expenses} + \frac{\text{Rate}}{100}\,\sum \text{Expenses} $$

Example

  • Venue: €500
  • Catering: €300
  • Decorations: €100
  • Subtotal: €900
  • Service Charge (10%): +€90
  • Total: €990

Frequently Asked Questions

Can I remove an expense row?

Yes—click the “–” next to any row (after you’ve added at least one extra row).

What if I have no extra charges?

Set the Tax/Service Charge percentage to 0% and it will be ignored.

How precise are the totals?

Costs are rounded to two decimals—suitable for budget planning.
