About CostToUpgrade
We make 10 (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 standard construction rules of thumb and is exact for your inputs. Cost math multiplies those quantities by prices — either prices you enter, or, on our regional pages, a national average adjusted by a state cost index.
Those cost indices are directional estimates 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.
What estimates don't include
Unless a calculator explicitly asks for it, results exclude labor, tax, delivery, permits, and site prep. We call these out so you can add them from real quotes.
