EU Mortgage Calculator

The EU Mortgage Calculator uses standard amortization formulas and segmented schedules to approximate lender behavior for fixed-rate, variable-rate, and interest-only mortgages.

1. Loan amount

Loan amount = Home price − Down payment
        

2. Periodic rate and number of payments

Periodic interest rate = Annual rate ÷ payments per year
Payments per year = 12 (monthly) or 26 (biweekly)
Total payments (n) = Loan term (years) × payments per year
        

3. Fixed-rate / PRICE payment

Payment (M) = P × [ r / (1 − (1 + r)^(-n)) ]

P = loan amount
r = periodic interest rate
n = total number of payments
        

4. Variable-rate segments

For each reset segment:
  Use remaining balance as P
  Use segment rate as r
  Use segment length as n
  Recalculate payment
        

5. Interest-only + amortizing tail

Interest-only period:
  Payment ≈ Balance × periodic rate (+ extra principal if entered)

Amortizing period:
  Use remaining balance and remaining term in fixed-rate formula
        

6. Taxes, insurance, and HOA

Monthly property tax = Annual property tax ÷ 12
Monthly insurance = Annual homeowners insurance ÷ 12
Total monthly housing cost =
  Initial principal & interest payment
  + Monthly property tax
  + Monthly insurance
  + Monthly HOA / service charges
        

Use this calculator to approximate lender-style EU mortgage payments and total interest under different country structures.

Step 1: Enter home price and down payment

Start with the property price and your planned down payment. The calculator derives the loan amount.

Step 2: Choose country and structure

Select Germany or France for fixed-rate, Spain or Italy for variable-rate with explicit rate resets, or the Netherlands for interest-only followed by amortization.

Step 3: For variable-rate, define reset periods and future rates

Enter a reset period (e.g., every 5 years) and future rates. The calculator recalculates payments at each reset using the remaining balance.

Step 4: For interest-only, set the IO period

Choose how many years are interest-only. After that, the remaining balance is amortized over the remaining term.

Step 5: Add taxes, insurance, HOA, and extra payments

Include annual property taxes, insurance, monthly HOA/service charges, and optional extra payments to see a more complete housing cost.
