Welcome to the Annual Amortization Cost (AAC) Calculator! This tool helps you estimate the annual cost of loan amortization based on the principal loan amount, monthly interest rate, and the total number of monthly payments. Let’s explore how it works and its practical applications.

**Formula & Variables**

The formula for calculating the Annual Amortization Cost (AAC) is as follows:

$\mathrm{AAC}=\frac{P\times r\times (1+r{)}^{n}}{(1+r{)}^{n}-1}$

Here’s what each variable represents:

- $AAC$: This denotes the annual amortization cost.
- $P$: This is the principal loan amount, typically in dollars.
- $r$: This represents the monthly interest rate.
- $n$: This is the total number of monthly payments.

**FAQs**

**Q: How does the AAC differ from the total loan amount?**

A: The AAC represents the annual cost of loan amortization, taking into account the principal amount, interest rate, and repayment period. In contrast, the total loan amount refers to the initial sum borrowed, excluding interest.

**Q: Can the AAC change over time?**

A: The AAC remains constant throughout the loan term if the interest rate and loan duration remain unchanged. However, changes to either of these variables can impact the AAC.

**Q: Is a lower AAC always preferable?**

A: While a lower AAC indicates lower annual loan repayment costs, borrowers should consider other factors such as loan terms, interest rates, and fees when evaluating loan options. It’s essential to choose a loan that aligns with your financial goals and budget
