About OG Calc

Most online tools for this task bury what you need behind ads and forms. OG Calc takes the opposite approach: load the page, do the job, leave. Built to be the kind of tool you bookmark and use weekly: no surprises between visits, no degraded free tier, and a UI that gets out of the way. It pairs naturally with the other utility utilities here when you need to chain a quick workflow.
