Free construction tools and calculators
No signup, no email gate. Built on the same billing engine as BuiltSum’s paid product, so the math holds up when the GC checks it.
Billing and paperwork
The documents a GC, architect or owner asks for, built on the same engine as the paid product.
Pay Application Generator
Build an AIA-style G702/G703-style pay application with continuation sheet, retainage, and stored materials. Saves your SOV so next month is a roll-forward, not a re-type.
Open tool →Retainage Calculator
See retainage withheld, net payable to date, and your state's statutory cap — with a 50-state retainage law table.
Open tool →Schedule of Values Builder
Build a CSI-coded schedule of values that always sums to your contract value. Export to Excel or send it straight into a pay application.
Open tool →Change Order Generator
Generate a signature-ready change order PDF and see its effect on your contract sum and next pay application.
Open tool →RFI Form & Log
Write the question, propose the answer, print a PDF with a response block for the architect — and keep every RFI dated, numbered and visibly overdue when it is.
Open tool →Submittal Log
Track spec section, type, ball-in-court and dates, with anything past its response date flagged. Export to Excel when the GC asks for the log.
Open tool →Estimating and pricing
From quantities to a price you can defend: what an hour costs, what overhead needs, and what markup clears it.
Estimate Builder
Price a job from trade assemblies with your own labor rate, burden and markup, then hand the client a proposal PDF — and the schedule of values it becomes.
Open tool →Browser Takeoff
Open a PDF drawing, calibrate the scale against a known dimension, measure lengths, areas and counts — then send the quantities to the estimator. The file never leaves your machine.
Open tool →Labor Burden Calculator
What an hour really costs: your state's SUTA rate and wage base, workers' comp by trade class, benefits — and the cost per billable hour, not just per paid hour.
Open tool →Overhead Calculator
Total the costs no job pays for, then see them as a share of revenue, per billable field hour, and as the markup your target profit requires.
Open tool →Markup Calculator
Markup is not margin. Price a job both ways, and work out the markup your overhead and target profit actually require.
Open tool →Material calculators
Order quantities with waste, in the units suppliers sell — then send them to the estimator to price the labor.
Concrete Calculator
Slabs, footings, walls and round columns in one list: cubic yards with waste, 40/60/80-lb bags, and ready-mix truck loads.
Open tool →Concrete Block (CMU) Calculator
Blocks for any wall less openings, 80-lb mortar bags, and grout for solid or partially grouted cells.
Open tool →Brick Calculator
Bricks per square foot for modular, queen, king and utility sizes, mortar bags, and veneer ties at code spacing.
Open tool →Drywall Calculator
Sheets for walls and ceilings room by room, plus joint compound, tape and screws for the finish.
Open tool →Tile Calculator
Tiles and boxes with pattern waste, grout by joint size, and thinset by trowel notch.
Open tool →Siding Calculator
Squares with gables and openings, boxes or planks, starter, J-channel and corner posts.
Open tool →Insulation Calculator
Batts by bay, blown-in depth and bags for a target R-value, and spray foam board feet and sets.
Open tool →Stud & Framing Calculator
Studs, plates, headers and sheathing for every wall, with corners, intersections and openings counted.
Open tool →Gravel Calculator
Tons and cubic yards for crushed stone, pea gravel, road base or sand, with compaction for base courses.
Open tool →Topsoil Calculator
Cubic yards or bags for lawns, beds and raised beds, with settling built in.
Open tool →Cubic Yard Calculator
Any shape, any material: yards, tons and bags — plus bank-to-loose swell and truck loads for excavation.
Open tool →Paver Calculator
Pavers with pattern waste, compacted base, bedding sand, edge restraint and polymeric sand.
