About this calculator

Most online deck calculators are either useless (a single dollars-per-square-foot multiplier) or actively misleading (designed to underprice the project so a contractor can land the lead and upcharge later). We built this one because shopping for a deck without a realistic budget number is a bad way to start.

How the numbers are sourced

Pricing coefficients in the calculator are based on installed prices observed on Greater Toronto Area deck quotes through 2024 and 2025, with a modest pad to keep the high end of the range realistic for 2026 inflation. They are reviewed before each major site update.

We always show a range — never a single number. A deck quote that comes in at the low end of the range usually has tradeoffs (fewer cuts, simpler footings, no lighting, basic railing). A quote at the high end usually has reasons (premium boards, tricky access, complex layout, integrated features). Both are normal.

What we don't do

• We don't track you across the web. Analytics is cookieless and aggregated only.
• We don't sell or auction your contact details to a network of unknown contractors. We work with a small set of GTA-based deck builders.
• We don't require you to enter contact information to use the calculator. The form is opt-in, when you're ready for quotes.
