# jquery – Converting Excel formula to JavaScript Calculation

Questions:

I have this forumula in a Excel sheet :

`=IF(B\$3=0,B\$14*B\$2*B\$6,(1-((1+B\$3))^B\$6)/LN(1/(1+B\$3))*B12*B\$2)`

where cells:

B2 = 40000

B3 = 1.0%

B6 = 30

B12 = 10.0%

B14 = 20.0%

The excel produces the following result: 139,834

I started looking at the ‘else’ part seeing as B3 not equal to 1, however I having issues with my calculations in JavaScript. Below is what I got (code is inside a function):

``````    var B2 = 40000;
var B3 =  1/100;
var B6 = 30;
var B12 = 10/100;
var B14 = 20/100;

var calc = Math.pow ((1-(1+B3)),B6) / Math.log ( (1 / (1+B3)) * B12 * B2);

return ( calc );
``````

What I’m getting back is `1.2071318349401829e-61`

Anyone know where I’m going wrong or how I would go about getting the correct result in JavaScript?

Any help appreciated.

In excel you have

``````1-((1+B\$3))^B\$6
``````

which is the same as

``````1-(1+B\$3)^B\$6
``````

in javascript you have

``````Math.pow ((1-(1+B3)),B6)
``````

which is different
