DIY vs trade cost.

DIY vs tradesperson calculator factors time value. 200 DIY materials + 20 hours × 25/hour value (500) = 700 total vs 1,500 tradesperson quote = 800 savings. DIY wins financially when materials cheap and time available. Tradesperson wins for complex/skilled work where DIY would extend time or damage property.

Example: bathroom tiling project. DIY 200 materials + 20 hours of your time × 25/hour = 700 total. Tradesperson quote 1,500 (their time + skill premium + warranty). DIY saves 800 if you have time and skills. Risk: poor finish, damage, time overruns. Tradesperson advantages: experience, warranty, time saved.

DIY vs trade decision factors: (1) Skill level honestly. (2) Time availability. (3) Tools needed (factor purchase/rental cost). (4) Risk tolerance (electrical/gas: usually trade only for safety/regulation). (5) Quality requirements (selling property: trade typically). (6) Materials cost (DIY often saves 30-50% on materials trade markup). Skilled trade rates: plumber 40-80/hour, electrician 40-80/hour, builder 35-70/hour, tiler 30-50/hour, decorator 25-50/hour. Common DIY-friendly: painting, basic tiling, garden, flat-pack furniture. Trade-only: electrical (Part P), gas (Gas Safe), structural, plumbing (often). Hybrid: DIY simple + trade complex.

Run it with sensible defaults

Using diy materials cost of 200, your time of 20, your hourly value of 25, tradesperson quote of 1,500, the calculation works out to 800.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — DIY Materials Cost, Your Time (hours), Your Hourly Value (£), and Tradesperson Quote — do not pull with equal force. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.

How the math works

Savings = tradesperson quote - (DIY materials + your time × hourly value). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this without guilt

The figure here isn't a verdict on whether the spending is "worth it". That judgment is yours to make. What the number does is shift the question from "can I afford this?" to "is this what I want my money doing over a decade?". Both questions matter.

What this doesn't capture

The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
