Questions people ask

What is a zero-based budget?
A zero-based budget gives every dollar of your paycheck a job — bills, savings, spending — until the amount left to assign is exactly $0. It doesn't mean $0 in your bank; it means no dollar is left unassigned.
Does a zero-based budget mean $0 in my bank account?
No. It means every dollar is assigned a purpose, not spent. Money set aside for rent or savings still sits in your account until it's actually needed.
How do I split my bills between two biweekly paychecks?
Mark each monthly bill as 'Monthly bill' and the calculator splits it across the two paychecks you reliably get each month — so half of rent comes out of each check and the bill is always covered.
What is the half-payment method?
Paying half of each monthly bill from each of your two monthly paychecks. It keeps every bill funded without relying on the occasional third paycheck — which becomes bonus money instead of a rescue.
How much should I set aside each paycheck for annual or irregular expenses?
Enter the yearly amount and mark it 'Annual / irregular.' The tool divides it across every paycheck in the year, so the renewal month is a non-event — a $600/yr cost is about $23 from each biweekly check.
What should I do in a three-paycheck month?
If you're paid every two weeks, two months a year have a third check with your monthly bills already covered. That whole check is free — send it to savings, debt, or a goal.
Zero-based budget vs 50/30/20 — what's the difference?
50/30/20 splits income into three broad buckets by percentage. Zero-based budgeting assigns every dollar to the specific categories you choose, down to $0 — more precise and flexible, especially per paycheck.
How do I budget by paycheck with an irregular income?
Budget each paycheck as it lands using that check's actual take-home, funding your most important categories first. For very lumpy income, plan off your lowest typical check and treat anything extra as a bonus.
