Window Treatment Cost Estimator
Budget a whole home at once. Add a line for each group of windows, layer on fitting, fees, a discount, and tax, and see the total and the cost per window.
Estimated cost
How the estimate adds up
The calculator multiplies each line’s window count by its unit price to get a treatments subtotal, then adds installation for every window and any one-off measuring fee. A whole-order discount comes off next — the kind of deal you often get for doing a full house at once — and sales tax is applied to what remains.
The result is a realistic total plus the average cost per window, so you can weigh a premium fabric in the living room against stock shades in the bedrooms and see the effect on the bottom line before you buy.
Frequently Asked Questions
How should I count my windows?
Count each opening you want to cover, then group them by the treatment they'll get. A house might have six standard bedroom windows at one price and two large living-room windows at another. Each group is a line in the calculator, with its own quantity and price.
What price should I enter per window?
Use the price of the treatment for a window of that size — a stock roller shade might be a modest figure, a made-to-measure wooden blind or lined curtains far more. If you're still shopping, put in a rough middle estimate and refine it as quotes come in.
Does it include installation?
It can. Enter a per-window installation figure and the tool multiplies it by the total number of windows, then adds any one-off measuring or call-out fee. Leave these at zero if you're fitting the blinds yourself.
Why is a per-window average useful?
The per-window figure lets you compare quotes and treatment choices on a like-for-like basis, and it's a quick sanity check: if the average has drifted far above what you expected, it's a prompt to revisit the more expensive lines or look at a cheaper fabric or operating style.
Estimates only, based on the figures you enter. Actual prices depend on size, fabric, operating style, and your supplier — always get a firm written quote before ordering.
