Two balances answer different questions
A spending ceiling, a set of estimates and a record of payments are related, but they are not the same number. BudgetBeacon keeps them visible together so a host can decide whether an attractive addition is affordable. It is useful when comparing an early draft, recording purchases or adjusting a plan after attendance changes.
The calculator accepts your figures rather than retrieving prices. A zero in the actual column means no spending has been recorded in that row. It does not mean the item is free, the invoice has been cancelled or the estimate can safely be ignored.
Use one currency and clear categories
Enter Total budget, Guests and a display currency. Each cost row uses Category | estimated | actual. Both amount columns are required, including an explicit zero for an unpaid category. Costs must be nonnegative; refunds and income need a separate record rather than negative cost rows.
Choose categories detailed enough to explain decisions without hiding the whole event in Miscellaneous. Venue, food, materials and contingency are reasonable starting points, but you supply the rows. Currency selection changes the label only. If a supplier quotes in another currency, convert and document that decision outside the tool before combining the numbers.
Read the arithmetic accurately
Planned is the sum of estimates. Actual is the sum of recorded actual amounts. Remaining equals Total budget minus Actual; Unallocated equals Total budget minus Planned. Actual per guest divides recorded actual spending by the entered guest count. These figures can move in different directions, especially when invoices are still unpaid.
The over-budget flag depends on actual spending exceeding the ceiling. Estimates can exceed the ceiling while that flag remains false; the separate allocation warning makes that situation visible. No figure represents a bank balance, payment authorization, tax calculation or live supplier commitment. Before buying anything, review obligations still sitting in the estimated column.
Fictional example: ten guests and a 500-unit ceiling
Select USD and enter ten guests, with these rows: Room | 150 | 150; Food | 200 | 180; Materials | 60 | 45; Reserve | 50 | 0. The estimates total 460 and recorded actuals total 375. The result shows 125 remaining, 40 unallocated, 37.50 actual per guest and no actual overspend.
The difference between 125 and 40 is not spare money discovered by the calculator. Some estimates have not become payments, and the reserve remains deliberately unspent. If food actuals later rise from 180 to 330, total actual spending becomes 525. Remaining is then −25, actual per guest is 52.50 and the over-budget flag becomes true. The estimates stay 460 until the host revises them.
The host uses the first result to ask which obligations remain, and the second to decide what spending must stop or be reduced. Both are fictional arithmetic examples, not recommendations about what a room or meal should cost.
| Category | Estimated | Actual |
|---|---|---|
| Room | 150 | 150 |
| Food | 200 | 180 |
| Materials | 60 | 45 |
| Reserve | 50 | 0 |
| Total | 460 | 375 |
Keep the plan explainable
Record taxes, delivery and rentals in the appropriate rows instead of assuming the tool adds them. Keep contributions or ticket income separate and set the ceiling from money actually available. For a shared event, agree who approves purchases before helpers treat Remaining as permission to spend.
Update the guest count when using the per-person result. Fixed room costs do not shrink merely because fewer people attend. Save after reconciliation and retain receipts outside the calculator. Copy or export the result for discussion, clearly labelling it as a record of entered figures. Local storage is useful for continuity, but it is not an accounting archive or cloud backup.
Questions before you begin
Can the estimate exceed the ceiling before actual spending does?
Yes. Planned allocations and actual overspend are separate checks. Read Unallocated even when the actual over-budget flag is false.
Does changing USD to EUR convert my figures?
No. The same numbers remain. Use a single recording currency and perform any necessary conversion independently.
Can I record a refund as a negative amount?
Negative cost entries are not supported. Keep a clear refund record separately and enter the reconciled nonnegative actual amount when appropriate.
Is actual per guest the meal price?
No. It includes all recorded actual categories divided by the entered headcount. It is an all-in recorded cost, not a food-only quotation.
