    it becomes many websites to have a calculator so that visitors can make an estimate of the things they are going to have bargain with.
    wpforms is one of the best option for this purpose.
    I have a query about whether we would be able to make an age calculator with the help of wpforms as it is required for many educational websites for eligibility purposes?

      It would depend on what feature you are looking for, from the sound of it WPForms should be able to make a calculator for your needs.

    Looking for a plugin I can use to drop any excel calculator into a post. Without bringing in the entire file, all the extra blank cells etc. I make them myself. Don’t need someone to do that. But I need to be able to drop them in and make them work.
