Joomla! 26 TAX Calculators

Target: **INBOX** Example: **INBOX** I need help, not developer Extension. But the extension can be edit. OK? General: 1.- Tax Calculator component for Joomla can be Extension, Plugin, Component. 2.- One calculator component which will perform multiple processes (calculations). In total 26 different calculations. 3.- Different modules for different calculation processes. Some plugins, extensions or components to perform these procedures. Especially in converting currencies, it is not necessary to develop a new plugin. We can use any tool that already exists. The Process: 1.- I need a page like this, where you have 26 options like this page has , for example GENERAL Update quantities Updating and Surcharges Tax loss carryforwards Foreign currency converter Depreciation for the ISR ...etc Now if you click on any of these 26 options, for example you click on (( GENERAL ->Update quantities)) then this page opens up: **INBOX** So i want this pages too, with the same fiels, drop down boxes and other options. Now i want user to fill the details in, and press the button to see the result. Like this: (Attached File: Capture (1).png ) And the result will be generate on the basis of formulas that you will maintain in the back end of each of the 26 calculations. 2.- I need to design 3 pages, as follows Page 1- > main page where we have all 26 calculations. Page 2-> when the user click on any one of the calculation and new page open up, with the fields to be filled by the user. Page 3-> the result page. The Result: (For example) For calculate the "Cálculo integral de salarios" (By the way, my language is Spanish) The user guest on my website, the calculation is this way and view like this. URL EXAMPLE: **INBOX** So in my backend i need make are like this: --- Scenary --- * Will add 365 days a year minimum benefits, which in this case, Mexico, are holidays, vacation pay and bonuses. 365 15 (days of Christmas by law) 1.5 (25% of the 6 days of vacation for the first year that by law it is up) Important, 25% is related to the minimum vacation pay law. So wwe have a total of 381.5. A again we will divide that result by the number of days in the year, ie: 365. And the result will be an integrating factor equal to 1.0452. Now, to know our integrated daily wage, a salary Journal multiply, for example $ 100.00 by the factor calculated above. The result would be 104.5205, which is the equivalent of a minimum wage plus benefits Journal of Law. * --- ---- Ok, Is different for example to this: **INBOX** here, the user can fill the fields in fronted, but not requered edit formulas in the backend. Nothing more need the value of currencies, from somewhere to update these data. I know Extension: [login to view URL] Thanks! :)
