I built KaufKompass after noticing that most mortgage/affordability calculators are made by banks or brokers, so they're optimized to show you what gets approved, not what's actually safe for your budget.
Most mortgage calculators are built by banks or brokers, so they show you what gets you approved, not what's actually safe. KaufKompass is independent: closing costs by German state, a real bank-style affordability check, a full amortization schedule, and the number most buyers never see coming — your remaining debt when the fixed-rate period ends. 100% client-side, nothing uploaded, no bank ever sees your numbers.
A property investment calculator built specifically for German tax law. Real Section 32a EStG tax brackets, AfA depreciation (linear, degressive, Section 7b, historic building), Soli and church tax, single vs shared-room rental modeling, a 30-year cashflow projection, and a portfolio planner toward a net worth goal. Paste a listing from ImmoScout and it auto-fills price, size, and rent. Runs 100 percent client-side.
