公式
此计算器背后的数学公式，供您核对结果。
Hourly Rate
This converts your annual salary into an equivalent hourly rate based on your work schedule.
Example:
Input: Annual Salary = $75,000, Hours/Week = 40, Weeks/Year = 52
Calculation: 75,000 / (40 × 52) = 75,000 / 2,080
Result: ≈ $36.06/hour
Project Compensation
Multiply your effective hourly rate by the number of hours you plan to spend on the project.
Example:
Input: Hourly Rate = $36.06, Project Hours = 100
Calculation: 36.06 × 100
Result: ≈ $3,606
