What is an Amortization Schedule?

An amortization schedule is a table that outlines the payment plan for a loan, including the principal and interest paid each period, as well as the remaining balance. It is a crucial tool for borrowers to understand their loan obligations and make informed decisions about their finances.

Creating an Amortization Schedule

To create an amortization schedule, you need to know the following information:

Balance: The initial loan amount
Rate: The interest rate of the loan
Payment: The monthly payment amount
Interest: The interest paid each period
Principal Payment: The principal amount paid each period
Remaining Principal: The remaining balance after each payment

Example Amortization Schedule

Period	Balance	Rate	Payment	Interest	Principal Payment	Remaining Principal
5	$1,200	12%	$106.56	$12.00	$94.56	a.
6	$2,400	8%	$141.84	$19.20	$122.64	b.

How to Read an Amortization Schedule

An amortization schedule is typically presented in a table format, with each row representing a payment period. The columns show the following information:

Period: The payment period number
Balance: The remaining balance after each payment
Rate: The interest rate of the loan
Payment: The monthly payment amount
Interest: The interest paid each period
Principal Payment: The principal amount paid each period
Remaining Principal: The remaining balance after each payment

Calculating Interest and Principal Payments

To calculate the interest and principal payments, you can use the following formulas:

Interest: Interest = Balance * Rate
Principal Payment: Principal Payment = Payment - Interest

Example Calculations

Let's use the example amortization schedule above to calculate the interest and principal payments for each period.

Period	Balance	Rate	Payment	Interest	Principal Payment	Remaining Principal
5	$1,200	12%	$106.56	$12.00	$94.56	a.
6	$2,400	8%	$141.84	$19.20	$122.64	b.

For period 5, the interest payment is:

Interest = $1,200 * 12% = $144.00

The principal payment is:

Principal Payment = $106.56 - $144.00 = -$37.44

Since the principal payment is negative, it means that the interest payment is greater than the payment amount, and the balance will increase.

For period 6, the interest payment is:

Interest = $2,400 * 8% = $192.00

The principal payment is:

Principal Payment = $141.84 - $192.00 = -$50.16

Again, the principal payment is negative, indicating that the interest payment is greater than the payment amount, and the balance will increase.

Understanding the Remaining Principal

The remaining principal is the balance after each payment. It is calculated by subtracting the principal payment from the previous balance.

For example, in period 5, the remaining principal is:

Remaining Principal = $1,200 - $94.56 = $1,105.44

In period 6, the remaining principal is:

Remaining Principal = $2,400 - $122.64 = $2,277.36

Conclusion

An amortization schedule is a crucial tool for borrowers to understand their loan obligations and make informed decisions about their finances. By creating an amortization schedule, you can calculate the interest and principal payments for each period, and understand the remaining balance after each payment. This knowledge can help you make informed decisions about your finances and avoid any potential pitfalls.

Q: What is the difference between interest and principal payment?

A: Interest is the amount paid for borrowing money, while principal payment is the amount paid to reduce the balance. In other words, interest is the cost of borrowing, while principal payment is the amount that reduces the debt.

Q: How do I calculate the interest and principal payments?

A: You can use the following formulas:

Interest: Interest = Balance * Rate
Principal Payment: Principal Payment = Payment - Interest

For example, if the balance is $1,000, the rate is 10%, and the payment is $100, the interest payment would be:

Interest = $1,000 * 10% = $100

The principal payment would be:

Principal Payment = $100 - $100 = $0

Q: What is the remaining principal?

A: The remaining principal is the balance after each payment, calculated by subtracting the principal payment from the previous balance.

For example, if the balance is $1,000 and the principal payment is $100, the remaining principal would be:

Remaining Principal = $1,000 - $100 = $900
