How this tool works
Base estimate = hours × rate + fixed costs. Contingency is added as a percentage of that base.
Enter estimated hours, hourly rate, fixed project costs, contingency (%). Update the result, inspect it, then copy or download the output. Reset restores the example inputs so you can start a new calculation.
Example inputs: Estimated hours: 30 · Hourly rate: 40 · Fixed project costs: 150 · Contingency (%): 15.
