How these calculators work
Each one runs entirely in your browser. Money is added and multiplied with exact decimal arithmetic and rounded to the cent only for display, so totals add up. Each page explains the formula it uses, walks through an example and lists what it doesn't cover.
They're built by Worthbase, which does the same calculations continuously for everything your household owns and owes. It runs inside your AI assistant: you share a broker statement, bank statement or screenshot, and Worthbase records it, prices your holdings daily and keeps every cost base, gain and return exact.
