The General Rule is Take the Original Gravity and Subtract the Final Gravity then multiply that number by 131 and you will have your ABV%

There is no "one" right formula. Most people use: ABV = (og – fg) * 131.25
Mostly because it's simple to do by hand or calculator. Some people round 131.25 to 131.
A more complex equation which attempts to provide greater accuracy at higher gravities is: ABV =(76.08 * (og-fg) / (1.775-og)) * (fg / 0.794)
This alternate equation reports a higher ABV for higher gravity beers.
10 years from now there will likely be another tweak to the formula.

P.S. You never replied to my questions about your article about using a sous vide heater in a mash. I felt that the article is likely severely flawed as the author was misinterpreting how the device works. See: http://www.theelectricbrewery.com/forum/viewtopic.php?p=329791#329791

Brewers Friend has a nice calculator that tells you the ABV, Apparent Attenuation, and Calories

Avinash, this is your store / your website. We can't see the formulas you are using. We already explained above how to calculate ABV and provided the formulas for you. So you are best positioned to test this yourself to make sure this is working correctly. What formula you wish to use on your website is completely up to you. There is no "correct" formula necessarily as we explained above.

User Avinash has been deleting for registering with multiple accounts all advertising various homebrew/equipment websites that point to the same physical address in Texas. Links to their online shops have been removed. I had my doubts that this person was yet another offshore 'marketing' company that got hired to spam forums and social media accounts (EDIT: Confirmed by the shop that this is indeed someone from a marketing company out of India). Companies often hire marketing firms to boost their online presence and sometimes this gets offshored, but it usually completely backfires for them and actually hurts their SEO (Google search ranking). I often get panicked emails from companies who didn't realize who they hired, asking me to remove links that these spammers have posted since their Google ranking's going into the toilet ....
