Window Quote Calculator
Give your window company website a configurator that prices like your plant does. The homeowner describes up to three kinds of windows, each with width and height in inches, quantity, style (double-hung, single-hung, slider, casement, awning, picture, twin double-hung or picture with flankers), frame color, double- or triple-pane Low-E glass, obscure or tinted glass, grids between the glass, screen, tempered glass and exterior brickmould. Hardware finish, replacement or new-construction frame type, ENERGY STAR glass, installation, haul-away and delivery apply to the whole order. Prices are per window by style and united inches with percentage and per-window surcharges, a volume discount, an optional promotion and a minimum order, and the visitor downloads a PDF estimate.

Frequently Asked Questions
How are the window prices calculated?
Each style has a base price for a white vinyl window up to 72 united inches (width plus height). Every united inch above that adds a per-inch rate, and a twin or a picture with flankers is priced lite by lite plus the mull joints. Glass package, ENERGY STAR and frame color are percentage surcharges; glass type, grids, hardware, screens, tempered glass and brickmould are per-window options. All of these are constants at the top of the code.
Can I change the styles and options my plant offers?
Yes. Remove a style you do not make, add a new one with its base price, rename the colors or glass packages, and change any surcharge. The dropdown labels show the prices, so update them together with the constants.
Does the calculator handle installation?
Yes. The visitor chooses replacement (pocket) or new-construction (nailing fin) installation with a per-window rate, haul-away of the old windows and a flat delivery charge. Windows-only orders for customers who install themselves are supported too.
Can I offer a volume discount or a seasonal promotion?
Yes. The volume discount switches on at a number of windows you set and takes a percentage off the windows and the installation. A promotion percentage with a name shows a banner and a discount line; set it to zero when the sale ends. A minimum order always applies last.
What does the homeowner get after submitting?
A PDF estimate with a summary table, the specification of every window, the shared order options, next steps and terms, valid for the number of days you set. You get the lead with the contact details and the whole configuration.
