With vuejs 2  you could use vue2-filters which does have other goodies as well   npm install vue2-filters   import Vue from  vue  import Vue2Filters from  vue2-filters   Vue use Vue2Filters    Then use it like so      amount   currency       12345   gt   12 345 00   Ref  https   www npmjs com package vue2-filters

Try this  methods        formatPrice value            var formatter   new Intl NumberFormat  en-US                 style   currency               currency   PHP               minimumFractionDigits  2                     return formatter format value             Then you can just call this like     formatPrice item total

I used the custom filter solution proposed by  Jess but in my project we are using Vue together with TypeScript   This is how it looks like with TypeScript and class decorators   import Component from  vue-class-component   import   Filter   from  vue-class-decorator     Component export default class Home extends Vue       Filter  toCurrency     private toCurrency value  number   string       if  isNaN value             return                var formatter   new Intl NumberFormat  en-US             style   currency           currency   USD           minimumFractionDigits  0             return formatter format value           In this example the filter can only be used inside the component  I haven t tried to implement it as a global filter  yet

You can format currency writing your own code but it is just solution for the moment - when your app will grow you can need other currencies   There is another issue with this    For EN-us - dolar sign is always before currency -  2 00   For selected PL you return sign after amount like 2 00 zl    I think the best option is use complex solution for internationalization e g  library vue-i18n  http   kazupon github io vue-i18n      I use this plugin and I don t have to worry about such a things  Please look at documentation - it is really simple   http   kazupon github io vue-i18n guide number html  so you just use    lt div id  app  gt     lt p gt     n 100   currency      lt  p gt   lt  div gt    and set EN-us to get  100 00    lt div id  app  gt     lt p gt  100 00 lt  p gt   lt  div gt    or set PL to get 100 00 zl    lt div id  app  gt     lt p gt 100 00 zl lt  p gt   lt  div gt    This plugin also provide different features like translations and date formatting

UPDATE  I suggest using a solution with filters  provided by  Jess    I would write a method for that  and then where you need to format price you can just put the method in the template and pass value down  methods        formatPrice value            let val    value 1  toFixed 2  replace                   return val toString   replace   B     d 3       d   g                 And then in template     lt template gt       lt div gt           lt div class  panel-group v-for  item in list  gt               lt div class  col-md-8  gt                   lt small gt                     Total   lt b gt    formatPrice item total     lt  b gt                   lt  small gt               lt  div gt           lt  div gt       lt  div gt   lt  template gt    BTW - I didn t put too much care on replacing and regular expression  It could be improved enter code here   x000D   x000D  Vue filter  tableCurrency   num   gt    x000D    if   num    x000D      return  0 00   x000D      x000D    const number    num   1  toFixed 2  replace            x000D    return number toString   replace   B     d 3       d   g        x000D      x000D   x000D   x000D

The comment by  RoyJ has a great suggestion  In the template you can just use built-in localized strings    lt small gt       Total   lt b gt    item total toLocaleString      lt  b gt   lt  small gt    It s not supported in some of the older browsers  but if you re targeting IE 11 and later  you should be fine

I have created a filter   The filter can be used in any page  Vue filter  toCurrency   function  value        if  typeof value      quot number quot             return value            var formatter   new Intl NumberFormat  en-US             style   currency           currency   USD           minimumFractionDigits  0             return formatter format value        Then I can use this filter like this           lt td class  quot text-right quot  gt                 invoice fees   toCurrency             lt  td gt   I used these related answers to help with the implementation of the filter   How to format numbers as currency string  Check whether variable is number or string in JavaScript
