Window calculator online — estimate the cost and compare companies
The window calculator on OKNA.ua is a free online tool that helps you quickly estimate the approximate cost of a metal-plastic (PVC) window from your parameters: the opening size, the profile type and chamber count, the glazing unit, the number of sashes and the opening type. You set the configuration — the calculator shows an approximate price, after which you can compare offers from many window companies independently and choose the best value. OKNA.ua is a niche platform about windows and doors specifically, running for more than 25 years (since 1999): here you compare offers from many verified companies in one place, instead of buying from a single seller.
How to estimate a window's cost in the calculator
To get an approximate price, set the main window parameters in the calculator:
- The opening size (width × height) and the number of windows.
- The construction type and number of sashes — fixed, single- or double-sash, tilt-and-turn.
- The profile and chamber count — the frame depth and the number of profile chambers.
- The glazing unit — single- or double-chamber, standard or energy-efficient (i-glass, argon).
- Extras — windowsill, external sills, reveals, insect screen, installation.
The calculator instantly shows an approximate cost. This is a preliminary estimate for budget planning — the exact price for your opening is quoted by the chosen company after measuring.
What a window's price depends on
There is no single "per-window" price — the cost depends on the configuration, so companies calculate it individually for your opening. A window's price is affected by:
- Profile and chamber count. The material, brand and frame depth of the profile and the number of chambers (usually 3–7): the more chambers, the warmer the profile and the higher the price.
- Glazing unit. Single- or double-chamber (2 or 3 panes), standard or energy-efficient with i-glass and argon; an energy-efficient unit costs more but loses less heat.
- Size and number of sashes. A larger area and each additional opening sash with hardware raise the cost.
- Hardware. Opening mechanisms, micro-ventilation, anti-burglary elements.
- Installation and extra work. Removing the old window, fitting, windowsill, external sills, reveals.
In Ukraine, windows are manufactured to DSTU EN 14351-1:2020 "Windows and doors. Requirements. Part 1. Windows and external doors" (in force from 01.02.2021), and PVC profiles to DSTU B V.2.7-130. Confirm exact characteristics and the price with the company you choose.
Why the calculator gives an approximate price
The calculator computes the cost from typical parameters, so it shows an approximate rather than a final price. The real cost depends on the exact opening dimensions, the state of the opening, the floor, the chosen profile and glazing brand and the scope of installation work. That is why the calculator is handy for estimating a budget and comparing options, while the exact price is fixed by the chosen company after a free measurement.
