Enter your product’s coverage and your own local prices. Results are planning estimates; they do not establish a safe repair method.
Paint calculator
Four rectangular walls. Deduct doors and windows; ceilings are separate.
Formula & assumptions
Gallons = ((2 × (length + width) × height) − openings) × coats ÷ label coverage. Coverage of 350 is an editable example, not a product guarantee. Round to actual can sizes. Texture, primer and extra touch-up paint are not included. 1 US gal = 3.78541 L; 1 sq ft = 0.092903 m².
Manufacturer estimating guidance ↗Flooring calculator
Plan material quantity for one rectangular room. Add irregular areas separately.
Formula & assumptions
Required area = length × width × (1 + waste / 100). Boxes = area ÷ box coverage, rounded up. The 10% allowance is an editable planning assumption. Patterns, matching and complex cuts can require more. Ask the flooring supplier for your product and layout.
Caulk calculator
Estimate volume. Use the product’s permitted joint dimensions and backer requirements.
Formula & assumptions
Volume in cubic inches = feet × 12 × width × depth × shape factor. Divide by 1.8046875 to get US fluid ounces; include waste, then divide by cartridge size and round up. A triangular bead uses factor 0.5. This idealized geometry does not specify the correct joint design.
Choosing compatible sealant ↗Home repair cost estimator
Build a budget using prices or quotes you already have.
What is included
Subtotal = materials + tools + hours × rate + other + materials × tax / 100. Add the chosen contingency to that subtotal. Tax applies only to materials in this simplified model; enter additional local taxes under “other”. This is not a local market-price database or a contractor quotation.
Fix now or plan later?
Compare your own repair quote with a possible later scenario. This is not a prediction of failure, an insurance estimate or a safety clearance.
How the comparison works
Later scenario = assumed later repair + assumed damage/disruption. Difference = later scenario − today’s quote. Months are context only; this tool does not forecast inflation, probability, progression or expected loss. A cheaper scenario never makes an emergency safe to postpone. Values stay in your browser memory and are not saved.
