Calculate rate difference

How much does actually an extra 25 per day mean, how does that change my annual revenue/income? Will a three weeks delay negate the difference?

Assuming 100% utilisation upon contract start for 12 months (rate 1).

Hours per year

How many hours will you be available to invoice per year?

Hour per day

How many hours would you work and invoice for per day. Not including lunch.

Rate 1

Rate 2

Rate time unit

Bench time

How many invoiceable days before contract for rate 2 starts?

Any questions?
