    Custom Formulas to calculate your JIRA Fields

    Custom Formulas to calculate your JIRA Fields

    Dates, Durations and Execution plans.

    Field names just as you always see them.

    Executions plans

    With the refreshed look, we added date, durations calculators in addition to the numerical calculator. To control the calculators we added execution plans.

    Abacus allows you to easily select custom field names you already know. Using the @ symbol, you can discover custom fields in your JIRA that can be used in your calculations.

    You decide when and if any formula should run. You are in total control of your calculations.

    More details

    • Create complex formulas in JIRA.
    • Calculator supports exponential "^" and Modulus "%" operators in addition to standard +, -, / and * operators
    • Discover customs fields using @ symbol for your calculations.
    • Create unlimited formulas per project.
    • Construct Date formulas
    • Construct Duration formulas

    Summary: Nice app at a very affordable price that does exactly what it says. Great for project-based calculations. Have not found another app that can do field calcs in the JIRA On Demand environment. Suggestions: 1) Add Global control. When you have dozens of projects and you want to use the same roll-up across all of them, every project has to be configured individually. This is painful, particularly if the calculations are complicated (3+ fields). Recognizing it may not be possible to add controls at the Settings > Custom Fields level, one solution could be adding templates that allow copying of one or more formulas from project to project more easily. 2) Eliminate the reliance on Edit. When I add a new formula to a custom field, it will not automatically calculate even if the sum fields already have values (e.g., formula = A+B+C = custom field Z. Fields A, B, and C, already have values, but Z is still blank after adding the calc in Abacus). I have to edit the issue before the formula seems to take effect. 3) Add Read-only field support. It's confusing to the user being able to edit the destination field for my formula, even if the Abacus plugin eventually changes it back to the correct value. Please add support for the "Text Field (read only)" field type. Edit [3/30/17]: Have seen some temporary delays (15-20 minutes is longest reported so far) with the destination total field being updated after the source fields have data. Causes some confusion to users when the total does not update immediately. Edit [4/18/17]: RE: Delays, thanks for the response. Bulk edit actually works quite well; the changes are almost instantaneous. What I've seen are some calcs that simply never go through, no matter how long you wait. The only way to trigger a calc is to go in and manually change the Result field (e.g., to zero), update the issue, and then a few seconds later the calc actually works. Have not figured out the logic of why some issues calc fine from the get go, but others using the same calc in the same project require this follow up step.

    Thank you Zack. We appreciate the feed back.

    As for delays, are your users doing gigantic bulk edit of issues? If so, processing will not be instantaneous. Just like when you do a bulk edit in JIRA, it takes time to process each issue.

    not tested; loaded plug-in, tried to view on project, and got a blank page.

    We would love to know what went wrong in your case and assist you if you could contact support. There are cases where if you have altered your JIRA permissions, our add-on and any other connect add-on cannot load. Or it could be a browser update that hide our plugin. In other words, causes could be many and our tests show the add-on to be working properly.

    Good product. It does what it says which is exactly what I needed and no other add-ons for Jira Cloud offer. It can be improved (especially the UI), but I understand that it's a new product and it's gonna take a while for the product to solidify. I had a problem with multiple formulas not working on the same project. I got a reply from Mumo Systems within half an hour of posting a request and was on a call with them in about an hour! In less than 1.5 hours after the call they provide me with a workaround so I can get going with my project with the promise to fix the bug for good.

    The add-on shows up in the projects, but when you create a basic formula using addition etc, it does not calculate the totals. Nothing at all happens. We contacted their support, and received no response.

    Paid-via-Atlassian pricing FAQ

    How does cloud add-on pricing work?

    Cloud pricing is subscription based. You are eligible for support and automatic version updates as long as your subscription is active.

    When your subscription renews each month, your pricing tier for host products and add-ons is automatically adjusted (as necessary) based on the number of users in your instance.

    If you've opted for annual billing for your host product, add-ons are also billed annually. Annual subscriptions for this add-on include a discount (12 months for the price of 10).

    If add-on pricing changes after your initial purchase, there's a 60-day grandfathering period during which you can renew based on the old pricing.

    How do I determine my cloud pricing tier?

    The cloud add-on tier is set automatically based on the maximum tier of the licensed JIRA applications on your instance. For example, if you have JIRA Software (50 users) and JIRA Service Desk (10 agents) on the same instance, your add-on tier is 50 users.

    Do you offer academic, community, or open-source licenses?

    For server add-ons, purchase and renewal is half-price if you have an academic license for your Atlassian host application. Server add-ons are always free for community and open-source licenses. Cloud add-ons do not have discounted or free licenses.

    For more details about qualifying for special licenses, see here.

    Can I extend my free trial?

    For cloud add-ons, you cannot extend your free evaluation period. All cloud add-ons are immediately subscribed by a user, and we provide a free evaluation period. This is a minimum of 30 days and ends on the second billing cycle after you first subscribe to the add-on.
