Are DIY projects really cheaper than buying?

DIY can cut costs 20-60% when labor is the biggest line item, but savings disappear if you buy specialty tools for a single job. Compare store price to material cost plus tools plus your time valued at an hourly rate. If the gap is small, buying may be smarter.

Projects with simple joints, clear instructions, and forgiving materials favor DIY. Tasks needing tight tolerances or safety certifications—like exterior doors, gas work, structural framing, or tempered glass—are often cheaper and safer to buy ready-made or hire out. Include warranty value; purchased items usually come with returns and tested finishes.

DIY is cheaper when

• You already own the tools and can reuse offcuts.
• You need custom dimensions, colors, or storage layout.
• Failure risk is low (paint touch-ups, caulk, basic shelving).

Buy instead when

• Regulations or inspections apply (electrical, gas, egress windows).
• Factory finish matters, like cabinet doors or pre-hung doors.
• Delivery and assembly are bundled and faster than your weekend.

Track receipts, hours, and any redo costs after each project. Two or three comparisons will reveal your break-even hourly rate so you can decide quickly next time.
