DIY vs Hire Scorecard

First, it estimates how much your current skill confidence falls short of the skill level typically expected for the selected project type, then converts that “skill gap” into an overall risk factor. Next, it models time pressure by comparing your time available this week to your DIY time estimate, producing a time risk penalty. Finally, it applies budget penalties to DIY and hiring cost proxies, producing two 0–100 scores and a score gap that determines the recommendation.

The recommendation is highly sensitive to your chosen DIY time estimate and skill confidence—because both directly affect modeled risk. If your budget is tight relative to the tool’s cost proxies, the budget penalty can swing the decision toward hiring (or toward “Depends” if both are over budget). Also, the “High-risk” override means that for safety/code-critical work, low skill adequacy or insufficient time will usually push the result toward hiring unless you truly can’t afford it.

If your budget is set to $0 and both DIY and hire estimates are above zero, the tool will return “Depends: verify pricing/financing” with low confidence. If your time available is near zero or far below your DIY estimate, time risk jumps sharply, which can reduce DIY score even when your skill confidence is high. If the DIY and hire scores land within about ±12 points, the tool intentionally chooses “Depends” because the tradeoffs are too close to call confidently.

This calculator uses simplified cost and labor “proxies” by project type, so it will not match your local market rates, permit fees, or contractor availability. Skill confidence is treated as one number and can’t distinguish sub-skills (e.g., electrical vs plumbing), so the model may over/underestimate real difficulty. Use the verdict as a decision framework, then confirm with quotes or a scope review—especially for high-risk projects.
