Comments on: PHP Functions to Convert APR to APY and APY to APR https://www.brandonchecketts.com/archives/php-functions-to-convert-apr-to-apy-and-apy-to-apr Web Programming, Linux System Administation, and Entrepreneurship in Athens Georgia Thu, 29 Nov 2018 15:02:33 +0000 hourly 1 https://wordpress.org/?v=6.9.1 By: Brandon https://www.brandonchecketts.com/archives/php-functions-to-convert-apr-to-apy-and-apy-to-apr/comment-page-1#comment-917 Wed, 16 Apr 2008 01:45:25 +0000 http://www.brandonchecketts.com/archives/php-functions-to-convert-apr-to-apy-and-apy-to-apr#comment-917 I’ve tried to use variable names that make sense:

$rate = The interest rate as a decimal (ie 5% as 0.05)
$periods = The number of compounding periods (365 would be compounded daily)

I didn’t come up with the formulas on my own. I found them at The Finance Buff and just converted them to PHP functions. I’ve tried them out and the results appear to be correct to me.

Thanks,
Brandon

would you please show me with a step by step process.

Thank you, Jerry B.
