To remove the commas  you ll need to use replace on the string   To convert to a float so you can do the maths  you ll need parseFloat   var total   parseFloat  100 000 00  replace    g                     parseFloat  500 000 00  replace    g

Related answer  but if you want to run clean up a user inputting values into a form  here s what you can do   const numFormatter   new Intl NumberFormat  en-US       style   decimal     maximumFractionDigits  2        Good Inputs parseFloat numFormatter format  1234   replace    g         1234 parseFloat numFormatter format  123   replace    g         123     3rd decimal place rounds to nearest parseFloat numFormatter format  1234 233   replace    g          1234 23 parseFloat numFormatter format  1234 239   replace    g          1234 24     Bad Inputs parseFloat numFormatter format  1234 233a   replace    g          NaN parseFloat numFormatter format   1234 23   replace    g          NaN     Edge Cases parseFloat numFormatter format true  replace    g         1 parseFloat numFormatter format false  replace    g         0 parseFloat numFormatter format NaN  replace    g         NaN   Use the international date local via format  This cleans up any bad inputs  if there is one it returns a string of NaN you can check for  There s no way currently of removing commas as part of the locale  as of 10 12 19   so you can use a regex command to remove commas using replace    ParseFloat converts the this type definition from string to number  If you use React  this is what your calculate function could look like   updateCalculationInput    e    gt        let value      value   numFormatter format e target value      123 456 78 - 3rd decimal rounds to nearest number as expected     if value      NaN   return     locale returns string of NaN if fail     value   value replace    g          remove commas     value   parseFloat value      now parse to float should always be clean input         Do the actual math and setState calls here

This is the simplest way to do it  let total   parseInt   100 000 00  replace             parseInt   500 000 00  replace
