If you have any suggestions, found a bug, wanted to contribute a
translation to your language email me
Depending on time limits I will answer you.


  • Plugin administration has a very direct interface. Manipulating factors that affect price generating are easy to spot and tweaks.
  • Associated Widget provide instant prices to visitors by an interface that strive to be minimal yet explicit.


  1. Download and unpack plugin files to wp-content/plugins/calculator-tipar
  2. Enable Calculator plugin on your Plugins page in Site Admin.
  3. Go to the Calculator/PanelControl page in Site Admin and change plugin’s
  4. Make sure to change in wp-config.php the line “define(‘WPLANG’); ” to “define(‘WPLANG’, ‘en_EN’);” or to whatever language you want, for example ro_RO. Remember that till now there are only two translation files. You have to make a brand new one if you want the plugin localised in a language that doesn’t have a coresponding translation file
  5. Go to the Calculator/Calculator page to see short explanations about factors used in prices calculation.
  6. Have fun if posible!


How can be modified the way price curves are done? There is no related button / section on admin area ?

Short answer is nope! It can be done with this version. Next one, this issue will be addressed, that there will be more options to choose from how
prices will be calculated regarding copies volume. But if you fill adventurous just dive in javascript source code and find k variable commented as ‘factor used in moderate price with copies number’.
