I'm Elliot Vance. Stack Frame is a personal project rather than a company: I have a regular day job and I build these calculators in my spare time as a hobby, mostly by writing code with AI assistants and then checking the maths by hand against a worked example before a page goes live. The site started because I kept needing the same handful of numbers twice a month — freight class and pallet density at work, loan payoff and tax estimates at home. Instead of rebuilding the same spreadsheet every time, I turned each one into a small web calculator and put them in one place. I'm not an accountant, financial adviser, lawyer, insurance agent, engineer, appraiser or medical professional. I hold no licence in any of those fields and I don't work in them. Every tool here is an aid for estimating and comparing: formulas come from published references and official sources, reference values (tax brackets, contribution limits, freight indices) change over time, and a result is only as good as the numbers you type in. If something looks wrong, email [email protected]. I read every message, fix what is broken, and note the correction on the tool page.
