Formula - Percent Increase or Decrease

I am trying to show percent increase or decrease in the number of students who obtained a GED in Fiscal Year 2009 to the number of students who obtained a GED in Fiscal Year 2010. My formula:[Formula - 1st FY GED] - [Formula - 2nd FY GED]/[Formula - 1st FY GED]*100
 

I think the formula is right, but my numbers are these: 6-5 = 1, 1/6 = .16, .16*100 = 16.67%

The answer I get is -10,000.00% .  I expect a negative number since there was a decrease, but this is just not working.  I have spent many hours of trial and research trying to figure it out.  Does anyone know how I can get this to work right in a Summary Report?

Thank you

    You need parentheses:

    ([Formula - 1st FY GED] - [Formula - 2nd FY GED]) / [Formula - 1st FY GED] * 100

      Thank you so much, but this does not work either!  I am using the formula in a custom column in a summary report....any other ideas?

        Typically you can't do this kind of math within a Summary Report, you usually need to aggregate using Summary Fields to a higher level table, and then do the math there.  So, what are you grouping on in your Summary Report.  For example, let's assume you are grouping by State.  You could create a table with one record for each State.  You would then create a relationship where one State could have many Students.  You could create Summary Fields in that relationship to "count" the Students who got their GED in a specific year.  You would have as many Summary Fields as the number of years you want to compare.  Then in the "States" table, you would create a formula field for each set of years that you want to compare for that State.  You could create a report showing all of the States, the Summary Fields with the number of GEDs for each year, and the formula column showing the percent change.

        Hope that helps,   Keira

          People come to QuickBase Community for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

          1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
          2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
          3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
          4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
          5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
