Amortisation is the process of spreading out a loan into fixed payments over time, where each payment covers both the principal amount and the interest accrued.
To calculate amortisation, you can use the amortisation formula, which involves determining the periodic payment amount based on the loan amount, interest rate , and loan term.
To create an amortisation schedule, list out each payment period, calculate the payment amount for each period using the amortisation formula, and track the allocation of each payment towards the principal and interest.
The formula for the amortisation factor depends on the specific context. In the context of loan amortisation, the amortisation factor is used to calculate the periodic payment amount based on the loan amount, interest rate, and loan term. It is typically derived from the annuity formula.
