Frequently asked questions
What is the difference between amortized and equal-principal repayment?
With the amortized method the amount you repay each month (principal + interest) stays the same, making it easy to plan. With the equal-principal method the principal repaid each month is fixed and the interest gradually decreases, so early payments are larger but the total interest is lower.
How is bullet repayment calculated?
With bullet repayment you pay only the interest each month during the loan term and repay the entire principal at once at maturity. The monthly interest is constant, equal to the principal times the monthly rate.
