Borrowing Money: Fun Facts and Calculations

Curious about borrowing money?

How can we calculate the interest accrued when borrowing money?

Understanding Interest Accrual

When borrowing money, it's essential to know how much interest you'll be paying. Let's dive into the details!

When you borrow money, the lender charges you interest on the amount borrowed. This interest is an additional cost you must pay back along with the initial amount borrowed. It's crucial to understand how interest is calculated to plan your finances effectively.

Calculating Interest

To calculate the interest accrued when borrowing money, you can use the simple interest formula:

Simple Interest = Principal Amount x Annual Interest Rate x Time

For example, if you borrow $500 at an annual interest rate of 7.5% for 2 years, you can calculate the interest accrued as follows:

Principal Amount (P) = $500

Annual Interest Rate (r) = 0.075

Time (t) = 2 years

Simple Interest = $500 x 0.075 x 2

Simple Interest = $75

Therefore, the interest accrued on the borrowed amount is $75.

Total Amount to Repay

In addition to repaying the borrowed amount, you must also repay the interest accrued. The total amount you need to repay is calculated as:

Total Amount = Principal + Interest

Total Amount = $500 + $75

Total Amount = $575

So, in the given scenario, Lydia would have to pay back $575 in 2 years, including the principal amount and the accrued interest.
