About this calculator
When a reception runs long, vendors need a pre-agreed overtime rate rather than an awkward on-the-spot negotiation. This calculator computes an overtime rate as a premium over your effective base hourly rate — accounting for the fact that extra hours cut into your sleep, next-day setup, and staff overtime pay obligations — and shows the total overtime charge for a given number of extra hours.

Inputs
- Base package price: 3200 $

FAQ
Why charge a premium over the base hourly rate for overtime?
Unplanned extra hours push into a vendor's downtime, delay teardown and travel home, and can force overtime pay to hired staff — a 25%-50% premium over the base effective hourly rate is standard across photography, DJ, and venue contracts to compensate for that disruption and the lack of advance planning.
Should overtime terms be in the contract before the wedding day?
Always — negotiating a rate in real time during a wedding puts the vendor in a weak position (client is emotional, timeline is under pressure) and the client at risk of being overcharged. A pre-agreed per-hour overtime rate in the signed contract avoids both problems.
What happens if staff hit legal overtime thresholds?
If you have hourly W-2 employees working the event, federal law (and some state laws with lower thresholds) requires 1.5x pay for hours worked beyond 40 in a workweek — factor any resulting extra wage cost into the staffOvertimePay input so your overtime charge to the client actually covers it.
Do all vendor types charge overtime the same way?
No — photographers and videographers typically charge per additional hour of coverage, DJs/bands similarly, but venues often charge a flat per-half-hour late fee instead tied to their staff and cleanup schedule since their overtime cost structure (security, cleaning crew) is different from a mobile vendor's.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
