Please help with a fairly simple percentage calculation....

Joey Picerno

I am not very good with percentages in calculations. I am writing in VB(.net 2005). I have 3 textboxes. One is current pay, and one is new pay. Both DOUBLE values. I need to have a calculation that finds the percentage of the increase in pay after the current pay and new pay are entered in the textboxes. I also need a calculation that allows the user to enter the current pay and percentage(the 3rd textbox) of the increase and calculate the new pay. So there are actually two calculations. Please someone help me out with this. I know to someone who is good with calculations and percentages can figure this one out fairly quickly. Thank you!!!

u can do like.... suppose u r taking 2 textboxes one for input the number and 2nd for input the percentage like 10% of 100. now u can display the result in a label control like dim a,b as integer a=TextBox1.Text b=TextBox2.Text Label1.text=(a*b)/100

SSK. Anyone who says sunshine brings happiness has never danced in the rain.

This is why you need other skills than just programming to be a good programmer. ;) You calculate the difference relative to the original amount. So you get: percentage = ((newPay - oldPay) / oldPay) * 100 To calculate the new amount from the percentage, you can just convert the formula: newPay = oldPay + (percentage / 100) * oldPay

Despite everything, the person most likely to be fooling you next is yourself.

Wrong Forum...And In between, I don' t see any forum called Juniour School Problems at CP ;P

Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

What a ridiculous question to post in a progamming forum. If yuo don't know how to do calculations try Google, there are loads of pages devoted to all sorts of caluations from simple percentages to complex scientific formulae.

Look, if you have a problem with my post, DONT READ IT. Ive gone through this before on code project. Someone remarked that my post was dumb and shouldnt be here. Guess what? I dont really care whether you approve of my post being here or not. I know that most programmers enjoy writing equations and calculations so I was helping to give a couple of programmers something fun to do. And I do know how to do calculations, Im just not good with percentages. If you dont have something to add to the question I asked, dont post a reply. You are wasting your time trying to criticize people's posts in a forum. It is childish and rude. Dont you have something better to do with your time? Like I said, if you dont like it, DONT READ IT!!!!! That goes for the other guy that criticized my post too, both of you. Grow up and get a life! On the upside though thank you for your suggestion on using Google. However I already tried searching the web to find a solution and had no luck. THATS WHY I CAME HERE...

I know a lot of programmers enjoy cooking, but I wouldn't ask for a recipe in a programmng forum

Not very good at Google either then. The top entry of http://www.google.co.uk/search?hl=en&q=how+to+calculate+percentage&meta=[^] tells you in easy to understand terms. I, like most of the people who actually answer questions on CP and other forums, try and help those less experienced or who have real programming problems. To do this I have to read posts to see if I can help. There are more than enough questions posted where 2 minutes on Google would reveal the solution without people posting what, despite your claims, is nothing to do with programmng. Finally,

So your saying that programmers never use calculations and equations??? Also, if my question had nothing to do about programming how was user "Guffa" able to give me a correct response with an equation that could be utilized in VB??? You arent making any sense and again are being very childish. Just drop it and go do something that is actually productive.
