Step-by-step explanation:
The Zero-based budgeting technique assumes there will be no balance bought forward nor balance carried forward. Budget preparation for a particular period must start from zero or scratch.

If Sam has an income of $800 and expenses of $675, she has to re-work her costs again to ensure they match her income. The zero-based budget demands she draws her expenses list again and comes up with a way of spending the $125 difference.
