Understand the economics
Break-even, contribution margin per hour, opportunity cost, pricing, upsell profitability, and the numbers that determine whether a service is worth doing.
SigCalc
Practical business, estimating, and technical tools built specifically for window film and PPF professionals.
SigCalc helps window film and PPF professionals understand their numbers, estimate projects, calculate material needs, evaluate film applications, and make better business decisions.
Built around the decisions shops make every day
Some tools help answer technical questions in seconds. Others help reveal whether a service, price, or use of shop time is actually profitable.
Build better project estimates
Field-friendly tools for project measurements, material quantities, film usage, waste, labor assumptions, and installation requirements.
Answer application questions
Fast calculators for VLT, film-on-glass results, sealant requirements, product performance, and other practical installation decisions.
SigCalc Tools
The goal isn’t a collection of generic calculators. Every tool should solve a real problem encountered in the window film and PPF business — from quick technical calculations to project estimating and optimized film roll cut maps.
ESTIMATING
Featured • Optimized Roll Cut Map
Flat Glass Project Estimator
Build a complete flat-glass estimate by room and window, calculate project area and installed price, create customer proposals, then automatically generate an optimized film roll cut map from the same measurements.
Launch Estimator →
Turn window sizes into a cutting plan.
Compare roll widths, account for oversize, rotate cuts, reuse offcuts, handle seams when needed, and visualize how the project can be cut with less film waste.
TECHNICAL
Automotive VLT Calculator
Estimate installed VLT using the unfilmed glass VLT and manufacturer-published film VLT.
Launch Calculator →ESTIMATING
Edge Sealant Quantity Calculator
Calculate cartridges or sausages required from total window perimeter, triangular bead size, and waste allowance.
