# 21:7 Roster Salary Calculator – Three Weeks On, One Off

The 21:7 roster — three weeks on, one week off — is a high-income FIFO pattern used in remote mining and resource operations across Australia. With only one week at home between three-week swings, this roster is suited to workers focused on maximising earnings in the short term, paying off debt, or saving for major financial goals.

## What Is a 21:7 Roster?

A 21:7 roster means you work 21 consecutive days on site followed by 7 days off. The 28-day cycle repeats approximately 13 times per year, giving you around 274 working days — one of the highest annual totals. With 12-hour shifts, this translates to very high gross income. However, three weeks away from home is demanding, and this roster carries a higher burnout risk. It's most commonly found on ultra-remote sites in WA's Pilbara and Goldfields regions, and in the Northern Territory.
