Mod Request

I need an addon created that will allow a monthly payment to be displayed next to the product price within the product block.

I don’t need anything fancy, just a simple payment calculation based on the following formula:

(Price x 90%) / 17

Example: Price: $1452.00

Monthly Payment: $76.87

Downpayment: $145.20

If you can do this I’d like to get it done asap.
