Rostered Day Off (RDO) Accrual Calculator
Estimate how many rostered days off (RDOs) you accrue based on extra hours worked each week beyond a standard weekly hours target.
Your results
Calculation breakdown
- Excess hours
- Excess hours per week = actual hours worked − standard weekly target
- RDOs earned
- RDOs earned = (excess hours per week × weeks) ÷ ordinary hours in one RDO day
Worked example
Working 40 hours a week against a 36-hour target for 9 weeks accrues 36 excess hours, equal to 4.5 RDOs at 8 ordinary hours per day.
Assumptions
- RDO accrual rules vary significantly by award or enterprise agreement.
- Assumes excess hours accrue at a 1:1 rate rather than a loaded rate.
How this calculator works
Enter your standard weekly hours target and the hours you actually work each week to see how many extra hours accrue toward a rostered day off, based on the RDO accrual rule common in construction and similar awards. Divide accrued hours by your ordinary daily hours to see RDOs earned.
Frequently asked questions
How many extra hours make up one RDO?
This depends on your award; commonly it is the weekly excess hours accumulated until they equal one ordinary working day, which you can set here.
Do all awards offer RDOs?
No, RDO arrangements are specific to certain awards and enterprise agreements, often in construction and manufacturing.
What happens to unused RDO accruals?
This varies by agreement; some allow banking or payout of unused RDO accruals, others require them to be taken within a set period.
Actual entitlements can depend on your award, enterprise agreement, contract, employment status and individual circumstances.
