Hourly earnings after direct project expenses, before tax and overhead. The add-on is a proposal, not an amount already owed.
The math, without the mystery
Original hourly earnings = (fee − direct expenses) ÷ original hours. Revised hourly earnings = (fee − direct expenses) ÷ (original + additional hours). For positive earnings, the percentage reduction is additional hours ÷ total hours × 100. Add-on quote = additional hours × your extra-work rate. All inputs use the same currency; no currency conversion occurs. Extra expenses are not included in the add-on.
This estimates the effect of extra time on the original plan. It is not a timesheet or a measure of business profit. When expenses equal or exceed the fee, we show no percentage reduction.
