How to read the result
- What it means
- The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
- Calculation limits
- The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).
- Next step
- Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Glossary+−
- Baseline cost
An initial cost figure representing materials or a partial quote used as the starting point for scenario calculations.
- Contingency
A percentage added to an estimate to cover unforeseen costs discovered during the project.
- Overhead & profit
Contractor charges that cover business overhead and profit margin, typically included in professional bids.
Key takeaways
A fair DIY-vs-pro comparison counts materials, tools, your time and rework risk — not just the labour you save.

Frequently asked questions
Should I really value my own time?
Yes, if those hours have an alternative use (work, family). Set the rate to $0 to compare cash cost only.
What is the rework allowance?
DIY mistakes often waste materials. The % adds a realistic buffer for redoing parts of the job.
