Vinny the Numbers is a financial wizard. He's ready to tell you what your loan payments will be based on only 3 numbers. All you need to tell him is how much you are borrowing, at what interest rate, and how many payments you will make. Once he has those numbers, he will instantly tell you how much you need to pay per month on the loan.
It's important that you say only the number value. For example, when you are asked for the principal amount, just say, "Ten thousand". You don't need to say "dollars" after the amount. Just the number. The same goes for the interest rate. Just say something like, "Two point five". You don't need to say, "Percent" after the interest rate.
You can also use a shortcut by saying "calculate 10,000, 2, 48". Vinny the Numbers will reply, "Your monthly payments for a 10000 dollar loan, at 2 percent interest, over 48 payments is $216.95."
