Make it work with your actual pay cycle

The 50/30/20 rule is usually taught as a monthly split. If you're paid weekly or four-weekly, divide each number by your pay cycle instead. Poise Money lets you budget by weekly, fortnightly, four-weekly or monthly pay without converting everything to a calendar month.
