How is the payment calculated?
With an annuity loan the monthly payment is equal throughout the term. Each month consists of the interest part of the payment and a principal repayment - early on the interest share is larger, later it is smaller. The payment depends on the loan amount, annual rate and term.
How it is calculated
Formula
annuity payment: M = P × r ÷ (1 − (1 + r)⁻ⁿ), where P is the principal, r the monthly rate (annual ÷ 12) and n the number of months. Total paid = M × n; total interest = M × n − P.
Example
Loan 10,000 €, 8% per year, 5 years (60 months) → payment ≈ 202.76 €/month, total interest ≈ 2165.67 €.
