About CostToUpgrade
We make 69 (and counting) free calculators that turn measurements into materials, quantities, and a realistic budget — so you walk into any project, or any contractor conversation, already knowing the number.
Why we built this
Most cost questions online end in a vague range and a lead form. We wanted the opposite: fast, specific tools that do the arithmetic in front of you and explain exactly how they got there. Whether you're pouring a slab, replacing a roof, or building a deck, the goal is the same — a defensible number you can plan around.
Our principles
Show the math
Every calculator publishes its formula and a worked example. If you can't see how a number is produced, you can't trust it.
Respect your time and privacy
Tools load fast, work on your phone, and run entirely in your browser. We don't collect the numbers you enter.
Be honest about uncertainty
Estimates are starting points, not quotes. We label what's included and tell you when to confirm with a local pro.
How our estimates work
Each calculator is a pure formula applied to the values you enter. Quantity math — volumes, areas, board and bundle counts — follows published standards and established trade practice, and is exact for your inputs. Cost math multiplies those quantities by prices: either the price you enter, or a national baseline scaled by a regional cost index.
Those indices are directional figures meant for budgeting, not appraisal. Local labor rates, material freight, permits, and site conditions move the real number, which is why every result ends with the same advice: confirm with a licensed local professional before you commit.
The full detail — where each constant comes from, how often we re-review prices, exactly what our estimates exclude, how we handle corrections, and how the site is funded — is documented on our methodology page.
