"description": "F2 Tool works out your plan to age 100 from four numbers: your age, your net monthly salary, your savings and your monthly spending, in euros. It answers with three outcomes side by side (a bad run of markets, the middle path and a good run) and the earliest age you could stop working in each, so you never see the best case alone. Every amount comes in today's money first, with the euros of its year beside it, and every answer states its assumptions: the return before and after you stop, inflation, and that the money has to last to 100.\n\nThen test a decision against your plan: a home (the mortgage, the rent it replaces, the equity it builds), a car, spending more or less (once, every month or every year), or a new salary path. You get the plan with the change and without it, and a chart of both in the chat.\n\nIf you keep a plan at f2tool.com, link your account: the answers then run on your saved plan, test the what-ifs you saved, and tell you how you are doing from your monthly check-ins. Linking is optional. A linked assistant reads your figures, never your name, email or picture.\n\nF2 Tool gives no advice. Ask \"should I?\" and it shows what the numbers say under each choice. It names no fund, broker or bank, sells nothing and shows no ads, and it keeps none of the numbers you give in a chat. Every answer ends with a link that opens the planner at f2tool.com on your numbers, where you can keep your plan if you want to.\n\nMade in Bulgaria, in euros. It answers in English and in Bulgarian.
