Risk Scenario Explorer
Compare expected-value allowances for individual cost risks.
Define additional cost events separately from the base estimate
Risk register
| Risk | Probability % | Cost impact | Expected cost |
|---|---|---|---|
| A | £5,000.00 | ||
| B | £5,000.00 |
Combined expected allowance£10,000.00
Base plus expected allowance£110,000.00
Probability and impact
Calculation method and assumptions
Expected allowance = Probability × Impact; Combined expectation = Sum of individual expectationsBoth impacts are incremental to the base cost and must not overlap. This is a two-risk expected-value model, not a Monte Carlo simulation, P50 or P80 forecast or recommended contingency.
