Start with the decision

What total budget follows from the entered eligible base and contingency rate?

Small-business operators comparing their own cost assumptions.

From input to next step.

  1. 01

    Choose a consistent basis

    Choose which costs are eligible before applying a rate.

  2. 02

    Enter the assumptions

    Enter the rate as an explicit planning assumption and keep excluded pass-through costs separate.

  3. 03

    Review the result

    Review actual uncertainties and approval limits. A budget allowance is not permission to spend it.

A look inside

The example, in plain sight.

Fictional values from the workbook. Amounts are illustrative currency units, not a market rate or a customer result.

Project scenario
Project A
Eligible base costs
2,000.00
Contingency rate
10.0%
Excluded pass-through
300.00
Contingency amount
200.00
Total allowance
2,500.00

Before you use the result.

  • Do not apply the rate twice.
  • No probability is estimated.
  • Revisit the allowance after scope changes.

A transparent budget allowance, not a quantitative risk model.
