Get the measurements right before the contractor’s quote arrives.
Countertop slabs, recessed lights, deck stain, cabinet paint, epoxy, basement & bathroom renovations. The small math that decides whether a project stays on budget — or runs 30% over.
Eight calculators for the finish line of a renovation.
Countertop Calculator
Square footage from any combination of straight runs, L-shapes, and islands. Adds 10% waste, returns slab count and a low/mid/high install estimate for quartz, granite, and marble.
Can Light Calculator
Spacing & count for new construction or remodel cans, by room dimensions.
Recessed Lighting
Lumen-target version — converts task / ambient goals into fixture count.
Deck Stain Calculator
Gallons of stain by deck dimensions, board spacing, and how thirsty the wood is. Accounts for railings, fascia, and the second coat almost everyone forgets.
Cabinet Painting Cost
Per-door / per-linear-foot pricing for a full kitchen repaint. DIY vs. pro estimates, with a separate line item for the primer your contractor said you didn’t need.
Epoxy Resin Calculator
Volume of resin in ounces or milliliters — for a river table, tumbler, jewelry mold, or floor pour. Handles deep-pour and tabletop ratios, plus a working-pot-life timer.
Basement Renovation Cost
Finish a basement from bare concrete to livable space. Framing, insulation, drywall, flooring, electrical, plumbing, egress — per square foot breakdown and total estimate.
Bathroom Renovation Cost
Full gut or simple refresh: vanity, tub/shower, tile, plumbing fixtures, labor. Cost ranges by size and finish tier — includes typical hidden expenses like subfloor repair.
Three numbers between you and an accurate quote.
The contractor’s bid hides material multipliers, waste assumptions, and labor markups under a single round number. These tools pull the line items apart so you can ask better questions.
Measure the space
Length × width × height in feet. Round up — overestimating waste is cheap, running out mid-job is not.
Pick a finish tier
Budget, mid-grade, premium. Each tool ships with regional 2026 pricing so the result is in the right zip code.
Sanity-check the quote
If a contractor’s number is more than 20% off, ask which line item differs. Usually it’s waste or labor — both negotiable.
