# Frends BizTalk Migration ROI Calculator > Free calculator that estimates the investment, savings, payback period and 3-year ROI of migrating from Microsoft BizTalk Server to the Frends low-code iPaaS. The Frends BizTalk Migration ROI Calculator helps IT directors, IT managers, enterprise architects and integration leads plan a move off Microsoft BizTalk Server. Given the number of orchestrations, send ports, receive locations, developer hourly rate and current BizTalk monthly license cost, it returns integration complexity, migration effort in hours, total migration cost, recommended Frends tier, annual license and development savings, payback period and 3-year ROI. Effort assumes roughly 3 days per orchestration and 0.5 days per send port or receive location, adjusted for complexity. BizTalk licensing is assumed to be 20-30% more expensive than the equivalent Frends configuration. Development on Frends is assumed to be 50% faster than traditional BizTalk development. ## Pages - [BizTalk Migration ROI Calculator](https://biztalkmigration.frends.com/): Free interactive calculator for migration cost, savings, payback and 3-year ROI from BizTalk to Frends. ## Optional - [Frends iPaaS](https://frends.com/ipaas): Overview of the Frends low-code integration platform features. - [BizTalk alternative platform](https://frends.com/use-cases/biztalk-alternative-platform): Frends positioned as the modern alternative to Microsoft BizTalk Server. - [Veho Group customer story](https://frends.com/customers/veho): Veho Group accelerated time-to-market by 90% and cut development time by 50% with Frends. - [Frends documentation](https://docs.frends.com/en/): Product documentation for the Frends platform. - [Frends customers](https://frends.com/customers): Customer success stories. - [Frends](https://frends.com/): Frends company website.
