Flat Rate Math

What to charge to add new receptacle from existing circuit (open access)

This is a device swap or addition, the bread-and-butter work where minimums decide whether you profit. Figure about 1.5 hours on a Normal run, with roughly $30 of material at contractor cost before markup. At a $120/hour shop rate - the worked example we use across this site - the flat-rate math for "add new receptacle from existing circuit (open access)" comes out like this:

Easyeverything cooperates: good access, sound wiring, no surprises$185
Normalthe typical version of this job in an occupied home$220
Hardpoor access, aged or altered wiring, extra protection or staging$285
Easy $185Normal $220Hard $285

Same math: hours x grade x your rate, plus material at 25% markup, rounded up to $5. Don't know your rate? Find it free in two minutes.

What makes this job Easy or Hard

Device work grades mostly on what you find behind the plate. Easy is a healthy box, copper conductors with slack, and a device that comes out clean. Normal is the usual mix: paint-sealed plates, short conductors, a crowded box, backstabbed connections you re-terminate properly. Hard starts when the box is damaged or undersized, the wiring is aluminum or cloth-covered, there is no ground where the new device needs one, or you are fishing a new run through insulated finished walls. Anything fished is a different animal from anything with open access - that is why the add-a-receptacle tasks appear twice in the book. Old work boxes in plaster, mirrored walls and tiled backsplashes all push toward Hard. The part is cheap; the grade is about the wall around it.

Don't forget

Small device jobs live or die on the minimum job charge. If your minimum is $150, a $70 receptacle swap is a $150 ticket unless it rides along with other work - say so on the phone.

Questions

Why is there a price range instead of one number?
The grades price the wall, not the part. A receptacle in an open garage and the same receptacle behind a tiled backsplash with short aluminum conductors are different jobs at the same hourly rate.

Is it worth doing one small device swap on its own?
Only at your minimum job charge. Most shops set a $100-150 minimum so a single-device visit still covers the drive, setup and paperwork - or they bundle it with other small tasks on the same visit.
