Frequently Asked Questions
What is an annuity loan?
An annuity loan has constant monthly payments throughout the term. Each payment consists of an interest portion and a repayment portion. As the loan balance decreases, the interest portion shrinks and the repayment portion grows.
How is the annuity calculated?
The annuity equals interest rate plus initial repayment rate, multiplied by the loan amount, divided by 12. For example, 100,000 euros at 3% interest and 2% repayment yields a monthly annuity of about 417 euros.
What is the Annuity Calculator?
The annuity calculator computes the constant annual or monthly instalment (annuity) of a loan from the amount, interest rate and term.
How does the Annuity Calculator work?
The annuity is calculated using the annuity formula: instalment = loan * (q^n * (q-1)) / (q^n - 1), where q = 1 + rate/12 and n = number of instalments. The calculator shows the repayment schedule and total cost.
Key Data and Facts
The annuity stays constant while the interest portion falls and the principal portion rises. Advantage: predictable fixed payments. Choose a high initial repayment when rates are low.
