I will include an example from the game. Right now I could borrow $100,000 for one year at $2,277 for 52 weeks. This would be $18,400 in total interest and a total repayment of $118,400. This is all good so far. The problem is that the game calls this an 18.4% "interest rate." In fact, the interest rate on this loan is much higher than 18.4% because the principle is being paid off over time, but the amount of interest charged doesn't go down. I would be paying interest on money I have already paid back. I tried to match the terms of this loan using the loan calculator and it is actually 34% APR. Look at the top option, "Amortized Loan", at the link.

I can also borrow $100,000 for five years at $487 for 260 weeks. The game calls this 26.% interest, but it actually works out to be about 9.8% interest. Again see the link and look at the top loan option "Amortized Loan."

1yr loan = 34% APR
5yr loan = 9.8% APR
The rates listed in-game are misleading. It's not that big of a deal because the actual repayment amounts are accurate. I love this game, and I only hope to be helpful.
