Painting Cost Calculator
Estimate what interior, exterior, cabinet, deck or commercial painting costs in Greater Cincinnati, per room, per square foot, in about ten seconds.
Pick what you are painting, put in the size, and this painting cost calculator will give you the range a job like yours typically lands in across Greater Cincinnati. It covers interior painting cost per square foot, exterior, cabinets, deck and fence staining, and commercial painting cost per square foot.
It uses the same 2026 market rates as our painting cost guide, so the two will never disagree.
How This Painting Cost Calculator Works – and Where It Stops
The math is straightforward: the calculator applies the per-square-foot and per-room rates we see across Hamilton, Clermont and Warren counties, then adjusts for the two variables that move price most predictably, ceiling height on interiors, and the condition of the existing finish on exteriors.
What no calculator can price is the thing that actually decides your number:
- What is under the paint. A wall that needs skim coating and a wall that needs a wipe-down are the same square footage and nowhere near the same job.
- How many coats the color change needs. Dark to light is a primer plus two finish coats. Greige to greige is often two.
- Access. Stairwells, second-story exteriors, and anything over a conservatory or deck need staging, and staging is time.
- Trim volume. Crown, chair rail, wainscot and six-panel doors are slow brushwork, frequently more labor than the walls around them.
- Surprises. Rot behind siding, wallpaper that takes the drywall face with it, a bathroom fan that has been venting into the soffit for ten years.
That is why a calculator gives you a range and an estimator gives you a price. Use this to budget and to sanity-check the quotes you receive; use a walkthrough to get a number you can actually hold someone to.
FREQUENTLY ASKED
How accurate is this painting cost calculator?
It is accurate as a budgeting range, not as a quote. The rates behind it are the ones we genuinely see across Greater Cincinnati in 2026, and for a straightforward job in sound condition the real price usually lands inside the range. What it cannot see is surface condition, how many coats your color change needs, access and staging, and trim volume, which together account for most of the variation between two houses of identical size. Treat the output as a budget, then get a written estimate.
What is the interior painting cost per square foot in Cincinnati?
Roughly $1.75–$2.50 per square foot for walls only, and $2.75–$4.00 per square foot once ceilings and trim are included. Those are square feet of floor area, not wall area. A 2,000 square foot home therefore runs about $3,500–$5,000 for walls and $5,500–$8,000 for the full interior, which matches the $3,000–$8,000+ range we quote for whole-home interiors.
What is commercial painting cost per square foot?
Open-plan office space runs $1.25–$2.50 per square foot, retail and restaurant $2.00–$3.50, medical and senior living $2.25–$3.75, and warehouse or industrial $1.00–$2.25. The variation between them is not the painting, it is the scheduling, the low-VOC and infection-control requirements, and how much finish detail the space demands.
How do I calculate deck staining cost?
Measure length by width for the deck surface. For a fence, multiply length by height, and double it if both sides are being stained. Staining generally runs $2–$4 per square foot, with most residential decks landing between $1,000 and $3,500 all in. Railings and spindles add disproportionately to labor because they are all edges, a deck with heavy railing can cost more than a larger deck without.
Why is the range so wide?
Because prep is the price. On two houses of identical size, the one with a failing finish can cost 40–60% more, and that difference is labor hours rather than materials. The low end of every range assumes a sound surface needing a wash and two coats; the high end assumes real scraping, sanding, priming and repair. Until someone has walked the property, both ends are genuinely possible, and any contractor who gives you a firm price over the phone is guessing at one of them.
