Calculating Amortizations
Amortization calculations, which also use the TVM variables,
determine the amounts applied toward principal and interest in a
payment or series of payments.
To
calculate amortization:
1. Change the display mode to the accuracy you want, such as 2 Fix
mode.
2. Start the Finance Solver.
3. Check and set these TVM conditions:
■ Number of payments per year.
■ Payments at beginning or end of periods.
