phpshane Posted January 4, 2008 Share Posted January 4, 2008 Hi All I'm new to php so please be kind. Within osCommerce V2.2 RC1, (products_price) I'd like to add two monthy apr monthy payment amount below the price of the product. One showing a single amount of 24 months and another showing 36 months. Their seem to be plenty of calculator out there, but all to calculate the full amount over a 24 month or 36 month showing every piece of detail. I just like some guidance on how to achive a simple monthy figure below the products_price! Regards. Shane. Quote Link to comment Share on other sites More sharing options...
hitman6003 Posted January 4, 2008 Share Posted January 4, 2008 Not sure about oscommerce, but if I remember high school math correctly, interest can be calculated as so: $total_with_interest = $price * pow((1 + $interest_rate), $years_financed); Course, i could be completely wrong....

hitman6003 Posted January 4, 2008 Share Posted January 4, 2008 $interest_rate should be expressed as a portion of 1...i.e. 5% interest would be ".05". Quote Link to comment Share on other sites More sharing options...
