- The result shows subtotal, buffer, net cost, and break-even per guest.
- Use conservative estimates for food, venue, and contingency so the budget is not too optimistic.

- Check the result and adjust assumptions before relying on it.

FAQ
What is the buffer for?
It adds a contingency amount for price changes, waste, extra guests, or forgotten small costs.
What is break-even per guest?
It is the net amount each guest would need to cover for the event to pay for itself.
Can sponsor money be included?
Yes. Put sponsor or covered amounts in the sponsor field so they reduce the net cost.
