Introduction

In this article, we will explore the concept of monthly payments and compound interest. We will calculate the total amount paid over 36 months, the total interest paid, and the final balance in the account. This will help us understand how compound interest works and how it affects our savings over time.

Understanding Monthly Payments and Compound Interest

Monthly Payments: A monthly payment is a fixed amount of money paid at regular intervals, usually every month, to repay a loan or to save money in an account. In this case, we have 36 monthly payments of $325.

Compound Interest: Compound interest is the interest earned on both the principal amount and any accrued interest over time. It is calculated on a regular basis, such as monthly or annually, and is added to the principal amount. In this case, the interest rate is 3.5% compounded monthly.

Calculating the Total Amount Paid

To calculate the total amount paid, we need to multiply the monthly payment by the number of payments.

Total Amount Paid = Monthly Payment x Number of Payments
Total Amount Paid = $325 x 36
Total Amount Paid = $11,700

Calculating the Total Interest Paid

To calculate the total interest paid, we need to use the formula for compound interest:

A = P x (1 + r/n)^(nt)

Where: A = final balance P = principal amount (initial deposit) r = annual interest rate (in decimal form) n = number of times interest is compounded per year t = time in years

In this case, we have:

P = $0 (since we are only paying $325 per month) r = 3.5%/year = 0.035 (in decimal form) n = 12 (monthly compounding) t = 3 years

We need to calculate the final balance after 3 years, and then subtract the principal amount to get the total interest paid.

Final Balance = $0 x (1 + 0.035/12)^(12*3)
Final Balance ≈ $11,700.19

Total Interest Paid = Final Balance - Principal Amount Total Interest Paid ≈ $11,700.19 - $0 Total Interest Paid ≈ $11,700.19

Calculating the Final Balance

The final balance is the total amount paid, which is $11,700.

Conclusion

In this article, we calculated the total amount paid, the total interest paid, and the final balance in an account with 36 monthly payments of $325 and a 3.5% monthly compounded interest rate. We used the formula for compound interest to calculate the final balance and the total interest paid. This helps us understand how compound interest works and how it affects our savings over time.

Understanding the Impact of Compound Interest

Compound interest can have a significant impact on our savings over time. By earning interest on both the principal amount and any accrued interest, we can grow our savings faster than if we were only earning interest on the principal amount.

Example of Compound Interest in Real Life

Compound interest is used in many real-life scenarios, such as:

Savings accounts: Banks use compound interest to earn money on deposits.
Loans: Lenders use compound interest to earn money on loans.

To maximize compound interest, follow these tips:

Start early: The earlier you start saving, the more time your money has to grow.
Be consistent: Make regular deposits to your account to take advantage of compound interest.
Choose a high-interest rate: Look for accounts with high-interest rates to earn more interest on your savings.
