Fast, no-nonsense calculators for margin, break-even, ROI, loan payments, and more. Companion to operatorcalculators.com. Operator Calculators puts the small, everyday business math you reach for constantly — margin, markup, break-even, ROI, loan payments — one click away in your toolbar. No tab switching, no spreadsheet, no page reload. Type a number, see the answer. Included calculators: - Margin & Markup — cost and price → gross margin and markup - Break-Even Units — fixed costs, price, and variable cost → break-even volume - Profit Margin — revenue and costs → net profit and margin - Simple Loan Payment — principal, rate, and term → monthly payment - ROI — gain and cost → return on investment - Percentage / Growth Change — old vs. new value → % change - Markup ↔ Margin Converter — type either percentage, the other updates live Every card has a Copy Result button, and the popup remembers the last calculator you used so it reopens right where you left off. For anything that needs more than a couple of inputs — DCF, IRR, NPV, business valuation, SBA loan underwriting, DSCR, working capital, SaaS metrics — the popup links straight out to the full calculator on operatorcalculators.com. The extension stays fast and focused; the deeper tools live where they have room to work. Privacy: all math runs locally in the popup. The extension makes no network requests of its own and collects no data — the only permission it uses is local storage, to remember which calculator you had open last.
