You are expected to complete the following task within 72 hours of receiving the assignment. In order to inform borrowers about the final repayment schedule, we need to have pre- calculated repayment plans throughout the life time of a loan. To be able to calculate a repayment plan specific input parameters are necessary: • duration (number of instalments in months) • nominal interest rate • total loan amount ("total principal amount") • Date of Disbursement/Payout These four parameters need to be input parameters. The goal is to calculate a repayment plan for an annuity loan. Therefor the amount that the borrower has to payback every month, consisting principal and interest repayments, does not change (the last instalment might be an exception). The annuity amount has to be derived from three of the input parameters (duration, nominal interest rate, total loan amount) before starting the plan calculation.
