Not a fintech startup with buzzwords — a tool I wished I had when my brokerage and my spreadsheet did not tell the same story.
cashlog.org helps you understand your portfolio the way it feels in real life: with XIRR across all cash flows — buys, sells, dividends, coupons and FX. Bonds and foreign currency are built in, not “coming later”.
Everything runs locally in your browser. Your data stays with you. No subscription — a cashlog.org licence when you want to stay. Pricing and details on cashlog.org.
I come from a banking background — there you quickly see how professionally returns are discussed. Privately, my picture was often different: the brokerage shows +8 %, yet it still does not feel right because dividends, coupons or FX are missing.
As a self-employed person you manage a lot yourself — including your wealth. I maintained my portfolio in spreadsheets and broker views for years. At some point it was clear: either I accept rough approximations, or I build something that answers my questions.
Around me is a network of people with similar topics — long-term oriented, with ETFs, bonds, income, sometimes several currencies. The same question keeps coming up: “How much did I really earn?” Not the price alone, but what remains after all inflows and outflows.
That is what cashlog.org is for: calm, traceable, no social feed — so you base decisions on numbers you can trust.
