FinBuddy

Three quick calculators that add up to one picture of your finances: invest, mortgage and when can I stop working. No sign-up, no backend. Everything runs in your browser and is saved locally.

• Invest: how monthly contributions compound over time, and what they are worth in today's money.
• Mortgage: compare your current rate with a what-if, solve for term or payment, add one-off or yearly extra payments.
• Plan: a few quick questions to find out when you can realistically stop working.
• Dashboard: where you stand today and where you're headed, exportable as a 2-page PDF.

Also: named snapshots, shareable links, multiple currencies, English and Czech UI. Your numbers live in localStorage and never leave your browser.
