HOW IT WORKS
How the calculator works
Scroll through each step to explore the complete roadmap.
Enter property details
Start by entering your property purchase price. This is the total amount you plan to pay for the property. The calculator will use this to determine your loan amount and LTV ratio.
Key Actions
- Enter property purchase price in euros
- Consider property valuation vs purchase price
- Understand that banks use lower of purchase or valuation
- Account for IMT and other acquisition costs separately
Set your down payment
Enter your down payment amount. This determines your LTV ratio and affects interest rates. Non-EU residents typically need 30-40% down (60-70% LTV), while EU residents may qualify for 20% down (80% LTV).
Key Actions
- Enter down payment amount in euros
- Check LTV ratio display (should be 60-80% typical)
- Understand non-resident vs resident limits
- Consider impact on interest rate eligibility
Choose interest rate and term
Select your interest rate type (fixed or variable) and rate percentage. Then choose your loan term (15-35 years typical). Longer terms reduce monthly payments but increase total interest paid.
Key Actions
- Select fixed or variable rate type
- Enter interest rate (2.5-5.0% typical for 2026)
- Choose loan term (15, 20, 25, 30, or 35 years)
- Compare monthly payment vs total interest impact
Review your results
The calculator shows your monthly payment (principal and interest), total interest paid over the loan term, LTV ratio, and down payment percentage. Use these to assess affordability and compare scenarios.
Key Actions
- Review monthly payment amount
- Check total interest paid over loan term
- Verify LTV ratio (should match your eligibility)
- Compare different scenarios (terms, rates, down payments)
Understand affordability
Ensure your monthly payment stays below 30-35% of your net (after-tax) monthly income (DTI ratio). Portuguese banks cap DTI at 35% of net disposable income. Non-residents must provide income documentation from their home country.
Key Actions
- Calculate your debt-to-income ratio
- Ensure monthly payment ≤ 35% of gross income
- Account for all existing debts
- Prepare income documentation for bank application

KEY METRICS
Understanding mortgage metrics
Monthly Payment (Principal & Interest)
Your estimated monthly repayment amount. In early years, more goes toward interest; later years pay down principal faster.
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Tip: Keep monthly payment below 30-35% of your net (after-tax) income (debt-to-income ratio). Portuguese banks typically cap DTI at 35% of net disposable income for mortgage approval.
Lisbon Market: For a €400,000 property with 20% down (€80,000), expect €1,200-€1,600/month at 3.5% over 25-30 years. Premium areas require higher down payments (30-40% for non-residents).
LTV (Loan-to-Value) Ratio
Percentage of property value you're borrowing. Critical factor determining down payment requirements and interest rates.
LTV = (Loan Amount ÷ Property Value) × 100
Tip: Lower LTV (higher down payment) = better interest rates. Non-EU residents typically get 60-70% LTV (30-40% down). EU residents may qualify for 80% LTV (20% down).
Lisbon Market: Portuguese banks offer 60-70% LTV for non-EU residents, 70-80% for EU residents, and up to 90% for Portuguese residents. Higher LTV requires mortgage insurance (typically 0.5-1% of loan amount annually).
Total Interest Paid
Total cost of borrowing over the entire loan term. Shorter terms reduce total interest despite higher monthly payments.
Total Interest = (Monthly Payment × Term Months) - Loan Amount
Tip: A 20-year term vs 30-year saves significant interest (often €50,000-€100,000 on a €300,000 loan). However, shorter terms increase monthly payments by 20-30%.
Lisbon Market: On a €300,000 loan at 3.5%: 30-year term = €184,000 total interest; 25-year = €145,000; 20-year = €115,000. Premium Lisbon properties often justify longer terms due to appreciation potential.
Debt-to-Income (DTI) Ratio
Your total monthly debt payments (including new mortgage) as percentage of net (after-tax) monthly income. Portuguese banks apply the 35% cap to net disposable income, not gross.
DTI = (Total Monthly Debt ÷ Net Monthly Income) × 100
Tip: Portuguese banks use "taxa de esforço" (effort rate) applied to net (after-tax) income. Include all debts: existing loans, credit cards, car payments. Keep below 35% of net income for approval. Non-residents may face stricter limits.
Lisbon Market: For a €1,500/month mortgage, you need approximately €4,300+ net monthly income (€1,500 ÷ 0.35). This typically requires €6,000-€6,500 gross monthly income after accounting for taxes. Non-residents must provide 3-6 months of payslips and bank statements from home country.
