    How It Works

    Homeownership involves more than just mortgage payments. This calculator helps you understand the real monthly cost of owning your home by considering opportunity cost, property appreciation, taxes, maintenance, and other expenses. The result shows what your house "costs" you to live in, as if you were paying rent.

    The analysis includes opportunity cost - the return you could earn by investing your home equity elsewhere. Property appreciation partially offsets these costs, but taxes, insurance, maintenance, and financing costs add up. Understanding these costs helps you make informed decisions about buying vs. renting.

    This "implicit rent" calculation shows whether homeownership makes financial sense for your situation. If the implicit rent is higher than comparable rental properties, renting might be more economical, allowing you to invest the difference.

    Practical Examples

    Example: R$ 500,000 Property

    • • Purchase price: R$ 500,000
    • • Opportunity cost (10%): R$ 50,000/year
    • • Fixed expenses: R$ 12,000/year
    • • Property appreciation (4%): -R$ 20,000/year
    • • Net annual cost: R$ 42,000 (R$ 3,500/month)

    High Appreciation Scenario (8%)

    • • Same property with 8% appreciation
    • • Property appreciation: -R$ 40,000/year
    • • Net annual cost: R$ 22,000 (R$ 1,833/month)
    • • Lower implicit rent due to higher returns

    Frequently Asked Questions

    Include All Costs: Don't forget IPTU, condo fees, insurance, maintenance, and opportunity cost of capital.

    Conservative Appreciation: Use realistic appreciation rates based on historical data for your area.

    Compare with Rent: If implicit rent is higher than market rent, consider renting and investing the difference.

    Location Matters: High-growth areas may justify higher implicit rents due to appreciation potential.
