Exterior Cost per Square Foot
Work the rate two ways: multiply your siding area by a price per square foot to get a total, or divide a quote by the area to see the dollars per square foot a painter is really charging.
At $2.00/sq ft, 2,000 sq ft of siding is $4,000.00. Exterior painting runs about $1.50–4.50 a square foot all-in — a labeled band; enter the real price from your quote.
Calculator inputs
Price per square foot is the language painters bid in, so it pays to be fluent both directions. Feed the tool an area and a rate and it gives the total; feed it a lump-sum quote and the area and it hands back the implied $/sq ft, which is the honest way to line two bids up next to each other. A number well below the labeled band usually means prep was skipped; well above can mean premium paint, hard access or a padded quote.
You provide the rate and the quote, so the result is timeless — no stored prices to drift out of date.
Formula
cost = siding_area × $/sq ft and derived $/sq ft = quote_total ÷ siding_area
Compare the derived rate to the labeled exterior band (about $1.50–$4.50/sq ft all-in) as a sanity check, never as a verdict.
Worked example
2,000 sq ft at $2.00/sq ft is 2,000 × $2.00 = $4,000.00. Now reverse a bid: a $5,000.00 quote over the same area is $5,000.00 ÷ 2,000 = $2.50/sq ft — comfortably inside the labeled band, a reasonable sign.
What a per-foot number hides
- Same area, both ways. Use the identical siding area for the forward and reverse math, or the comparison is meaningless.
- Low is not always good. A rate under the band often means one coat where two were needed, or prep that was quietly dropped.
- High has honest causes. Stucco or brick, three stories, heavy scraping and premium paint all lift the legitimate rate.
- The band is a guide. It is a labeled planning range, not a rule — regional labor varies widely.
Reference table
| Siding | Labeled $/sq ft band | What drives it |
|---|---|---|
| Vinyl / lap siding | $1.50–$3.00/sq ft | Smooth — least paint & prep |
| Wood siding | $1.75–$4.00/sq ft | Sand/scrape and prime bare spots |
| Stucco | $2.00–$4.50/sq ft | Porous — soaks up more paint |
| Brick | $2.25–$4.50/sq ft | Very porous — masonry primer, often permanent |
Exterior repaints run about $1.50–$4.50/sq ft all-in (paint + labor + prep). These are labeled planning bands, a sanity guide only — you enter the real price from your own quote; stucco, brick and rough wood soak up more paint and prep than smooth vinyl or lap siding.
