Double Trouble
When I was eight, I wanted a toy and needed $10 to buy it. But, as usual, I was broken. I decided to ask my 11-year-old sister, Kathleen, for a loan. I went to her room, 1her for the cash. Laughing, she agreed to lend me the money, but2, "I will charge you 10 percent compound interest every 3until you pay me back."
"Compound interest—what's that?" I asked.
"Well, interest is what you call the4money borrowers have to pay back on a loan," she explained. "Compound interest means that the interest payments get bigger and bigger the5it takes you to pay back the loan. To repay the loan, you will need to give me $11 after one month. If you wait two months to pay me back, your6 will grow from $10 to $11. So I'll be charging you interest on $11. Then I will add that interest to the $11 you already owe me, for a 7of $12.10. That's what you'll owe after two months."
"Sure. I get it," I said. Though truthfully, I was getting 8.
Kathleen lent me the money, and I bought the toy. My birthday came a month later, and my mom gave me $10. 9, that was just the amount I needed to buy another toy I wanted10. I 11paying my sister for a month. After another month, I forgot about the loan.
Several months later, on Christmas morning, my sister and I each found a $20 bill in our stockings. I was just putting it into my pocket12Kathleen tapped me on the shoulder.
"Sorry, kiddo. That's mine. I'm 13your debt."
"Huh?" Then I14 the loan. "Hey! How can it be that much? I only borrowed $10."
"True," she said, "but interest has been compounding for eight months. Now you owe me $21.43." She paused, and then, smiling triumphantly, said, "You can pay me the $1.43."
I15to believe that a $10 loan could more than double so quickly. Much to my 16, my sister got her pencil and tablet and showed me exactly how it all 17.
My head18as I tried to keep track of Kathleen's calculations, but this time, I got the basic19of compound interest. I learned from this20experience that borrowing money can be "double trouble" in no time.
