Hourly Rate Glossary
Hourly pay, billable hours, overtime and effective rate definitions.
Quick definitions
Use this page as a plain-language reference while using the related tools. The goal is not to replace specialist advice; it is to make common calculation terms easier to recognize.
Why the terms matter
Most mistakes happen when two similar words are treated as the same thing. A rate is not the same as a total, a monthly number is not the same as a yearly number, and an estimate is not a guarantee. The linked tools show the formula so you can see which number is being used where.
Good checking habit
Change one input at a time, recalculate, and compare the result. That makes the most sensitive part of the calculation obvious.
