    Calculate your JIRA Fields

    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.
    • Increment fields and optionally set starting point, lower limit or upper limit.
    • Calculate dates
    • Calculate durations.
    • Formulate conditional executions.
    • Control execution of formulas using execution plan. Target specific issues using JQL and more.

    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.

    We discovered some client instances WebHook are delaying calling Abacus to do calculation. That is why there are some delays. We tested and verified this by turning on the WebHook on the said instance to call https://requestb.in. Our average response time is 110ms. Let Atlassian know that the WebHook in your instance is slow and they will take appropriate steps to fix the issue for your instance.

    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 app 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, you are automatically billed for host products and apps based on the number of users in your instance.

    If app 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?

    Apps are billed based on the number of users in your host product. JIRA Cloud apps are priced based on the maximum users of the JIRA products on your instance. For example, if you have JIRA Software (50 users) and JIRA Service Desk (10 agents) on the same instance, you pay the 50-user price for apps.Note: While this app has features specific to JIRA Service Desk, the app is technically available across the whole JIRA instance. Therefore the above guidelines for licensing across maximum users still apply.

    The pricing structure for cloud products and apps is as follows:

    • Monthly subscriptions with up to 10 host product users are billed at a flat rate price.
    • Monthly subscriptions with more than 10 users are billed per user, starting at the first user.
    • Monthly subscriptions with more than 100 users are billed per user. The table above provides example pricing at various user levels.
    • If per-user pricing is not yet available for this app, please contact the vendor for further information.

    If you've opted for annual billing for your host product, apps are also billed annually at a discount (12 months for the price of 10).

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

    Academic, community and open source licenses are not available for cloud apps.

    Can I extend my free trial?

    For cloud apps, you cannot extend your free evaluation period. All cloud apps 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 app.
