Worked example
The month adds up. The 20th doesn't.
Maya is paid 10,000 on the 5th and the 20th of every month, and puts half of each paycheck in her bills bucket.
Her bills are a phone plan of 1,000 due on the 8th and rent of 8,000 due on the 1st. Over the month, 10,000 goes into bills and her bills come to 9,000. On paper she's 1,000 ahead.
But rent is due on the 1st, before her next payday on the 5th. So the paycheck on the 20th has to pay it. That paycheck brings 5,000 of bills money for an 8,000 bill, so it's 3,000 short.
The paycheck on the 5th only has the 1,000 phone bill, which leaves 4,000 spare. The planner tells her to hold back 3,000 of it for the 20th. The other 1,000 is free to spend or save.

| 5th | 5,000 | 1,000 | Hold back 3,000 · 1,000 free |

| 20th | 5,000 | 8,000 | Short by 3,000 |
