Project Budget Planner
Use this calculator when you want a smarter starting point before a survey. It turns the biggest pricing variables into a clearer planning estimate, lead-time band, and shortlist of the details most likely to change the final quote.
This calculator gives a planning estimate, not a formal quote. Final pricing is confirmed after survey, specification, and site review.
Adjust the variables that move price fastest.
Start with a preset, then fine-tune the number of openings, material direction, glazing level, and the realities of the site.

What moves the number most?
