--- title: "Drivers: Global and Periodic Change" description: Jirav shipped two new features—Global and Periodic Change Drivers. Global Drivers are formulas that you create in Jirav to calculate other lines in the model that are applied everywhere. Periodic Change Drivers are useful for creating outputs that change over time using a predefined curve or step function image: https://www.jirav.com/hubfs/periodic%20change%20report%20-1.png --- ![](https://www.jirav.com/hs-fs/hubfs/Imported%20sitepage%20images/header-logo.png?width=98&name=header-logo.png) - [ Resources ](https://www.jirav.com/resources) - Menu / Resources - [Resource Center ](https://www.jirav.com/resources) Blogs and resources on all things finance, FP&A, and Jirav [Webinars ](https://www.jirav.com/webinars) Learn more about Jirav and FP&A from industry experts [Events ](https://www.jirav.com/events) See our upcoming calendar of events [Help Center ](https://help.jirav.com/) Guide on how to use Jirav - [ Company ](https://www.jirav.com/company) - Menu / Company - [About ](https://www.jirav.com/company) Learn about Jirav’s story and meet our leadership team [News Coverage ](https://www.jirav.com/news) See the latest news and highlights [Press ](https://www.jirav.com/press-releases) Recent company announcements and updates [Careers ](https://www.jirav.com/careers) View current job openings and learn how to join the Jirav Tower ![business_env](https://www.jirav.com/hubfs/business_env.svg) [ For Businesses ](https://www.jirav.com/reporting-planning-purpose-built-for-businesses) ![accounting_calc](https://www.jirav.com/hubfs/accounting_calc.svg) [ For Accounting & CFO Firms ](https://www.jirav.com/reporting-planning-purpose-built-for-accounting-cfo-advisory-firms) [ Get a Demo ](https://www.jirav.com/request-demo) [ Sign in ](https://app.jirav.com/) ![](https://www.jirav.com/hubfs/April2021/images/banner-shap.png) BLOG # Drivers: Global and Periodic Change [![](https://www.jirav.com/hubfs/April2021/images/fb-icon.png) ](http://www.facebook.com/share.php?u=https://www.jirav.com/blog/global-and-periodic-change-drivers/) [![](https://www.jirav.com/hubfs/April2021/images/tw-icon.png) ](https://twitter.com/share?url=https://www.jirav.com/blog/global-and-periodic-change-drivers/) [![](https://www.jirav.com/hubfs/April2021/images/in-icon.png) ](http://www.linkedin.com/shareArticle?mini=true&url=https://www.jirav.com/blog/global-and-periodic-change-drivers/&summary=&source=CeBIT) 1 minute read ![periodic change report -1](https://www.jirav.com/hubfs/periodic%20change%20report%20-1.png) Recently we shipped two new features—Global Drivers and Periodic Change Drivers. Drivers are formulas that you create in Jirav to calculate other lines in the model. Now you can create Global Drivers, which are applied to every plan, not just an individual plan. Periodic Change Drivers are useful for creating outputs that change over time using a predefined curve or step function. --- ## New Feature: Global Drivers Now you can create Global Drivers, which are applied to every plan, not just an individual plan. Even plans you create in the future will have these drivers. If you update these drivers, they automatically update in all the plans. This is very useful for defining formulas that remain the same in every scenario. For example, let’s say we want to plan rent expenses based on headcount growth. The formula for that will be an increase in rent expense for every 10 additional employees. In one of our plans, we may have high headcount growth while another plan may have a lower headcount. This means each scenario will yield a different value for Rent expense, but the actual formula used in every plan will be the same. ![rent formula-1](https://www.jirav.com/hs-fs/hubfs/rent%20formula-1.png?width=2241&name=rent%20formula-1.png) We now don’t have to go into each plan to create these new formulas manually. These redefinitions will automatically be available in every plan. *[Learn more about creating Global Change Drivers in the Help Center→](https://help.jirav.com/drivers/global-drivers)* --- ### New Feature: Periodic Change Drivers Periodic Change Drivers are useful for creating outputs that change over time using a predefined curve or step function. You can set the value to change monthly, or by any number of months. The curves can float with variable dates like Plan Start, Plan End or Plan Cutover Date—or you can anchor the curve to a specific point in time using an absolute date.  You can specify an initial seed value that is then changed over time. They can be used to make all kinds of assumptions like increasing contractor costs or ad spend over time. Absolute dates also help us model things like expected rent changes which may be tied to calendar years rather than planning windows. ![periodic change report -1](https://www.jirav.com/hs-fs/hubfs/periodic%20change%20report%20-1.png?width=2219&name=periodic%20change%20report%20-1.png)   [*Learn more about creating Periodic Change Drivers in the Help Center→*](https://help.jirav.com/drivers/periodic-drivers)   --- ## Jirav Pitched in the Finale of Finovate 2018 CEO Martin Zych pitched Jirav to 1,000+ attendees at the finale of [Finovate 2018](https://finance.knect365.com/finovatespring/) in Santa Clara May 8-11th. ![Martin at Finovate](https://www.jirav.com/hs-fs/hubfs/Martin%20at%20Finovate.jpg?width=1080&name=Martin%20at%20Finovate.jpg) ![Sameer Halai](https://app.hubspot.com/settings/avatar/be74fd75ac6ceefd595dcfaa5ab45ff2) ##### Sameer Halai Published May 15, 2018 ###### Related topics - [Product](https://www.jirav.com/blog/topic/product) ## Related blog posts ![driver-divided-by-rate-equals-output-equation](https://www.jirav.com/hubfs/Driver-based-model-diagram-square.png) Product #### What is driver-based modeling?
