HOW TO USE IT
How to use the Job Contingency Calculator
- 1
Define the base cost: The base cost is the estimate before contingency and markup. It should cover known scope, labor and materials.
- 2
Apply contingency separately: Contingency is a percentage of the base cost for uncertainty. Ten percent on $80,000 is $8,000, kept as its own line.
- 3
Mark up the cost plus contingency: Apply markup to the combined base plus contingency. A 15% markup on $88,000 is $13,200.
- 4
Show the pieces: The price is base + contingency + markup. On $80,000 that is $88,000 + $13,200 = $101,200. Use the Job Contingency Calculator to keep the split visible.
