Latin for "in proportion" — splitting an amount fairly according to each person's share.
What it means
Pro rata means dividing or allocating something proportionally rather than equally. If three people share a cost pro rata based on usage, each pays in proportion to what they actually used.
In Australian contexts you'll often see pro rata used for part-time leave entitlements, rent for a partial month, dividends, or refunds for a cancelled service. It ensures each party bears or receives an amount that matches their relevant share.
How it's used
Because she resigned mid-month, her final pay included her salary calculated pro rata for the days she worked.
