The repayment determines the period during which the loan is to be repaid. The higher you choose, the faster you can repay the loan. Almost all banks also allow special payments of up to 5% of the original loan amount. This calculator should give you a quick overview to determine how high your annual credit rate will be taking into account your ideas about the credit period. The interest rates that you find in the help text are intended to be an approximation of a possible interest rate. Play with the capital repayment to see how much you have to raise annually in order to repay a loan in the period you want.
