About Uma Carat

Last updated: 2026/10/22

Uma Carat is a free, unofficial planning tool for players of Cygames' Uma Musume Pretty Derby. It helps answer one practical question: will I have enough carats for the banners I want?

Plan around your next banner

Carats come from dozens of sources, each on its own schedule: daily logins, Team Trials on Mondays, club rank on the 1st, Champions Meeting and League of Heroes on the day each event ends, plus every event, login bonus and mission the game runs. Banners come and go on a two-week cycle that lines up with none of it.

Enter your carats and tickets, choose the income sources that match how you play, and add your target banners. The calculator walks the calendar forward day by day, showing the resources you can expect before each banner ends and carrying your planned spending into the next forecast.

You can compare multiple plans, estimate pull odds, plan paid step-up banners, track selector tickets and uncap crystals, browse the banner and event timeline, and prepare teams for Champions Meeting and League of Heroes.

Your plans stay with you

There are no accounts or sign-ins. Plans, teams, notes and preferences are saved in the browser on the device you use. They are not uploaded to a server. Browser storage can be cleared by you or your browser, so keep an exported backup of plans you want to preserve or move to another device.

The site is free to use. We do not run our own advertising. The Privacy Policy explains browser storage, traffic measurement and email feedback.

Where the numbers come from

The underlying methodology follows Henry's resource spreadsheet, the community reference the calculator grew out of. Daptrius created the spreadsheet, and much of the maths and data behind the projections comes from that work.

Understand the forecast

Banner dates, rewards and income rates are included in the site's data. Announced dates and estimated dates are distinguished in the planner. Future schedules can change, and your actual earnings depend on how you play. A projection is an estimate, not a guarantee.

The FAQ explains common settings, and the carat income guide walks through the projection step by step. Site updates appear on the Changelog.
