zero based budgeting
Zero based budgeting means you plan every naira of your income for a job before the month starts, so income minus allocations always lands on zero.
In plain English
Every first of the month, Aunty Rose sits at the dining table with her salary alert still glowing on her phone, a biro in one hand and an old exercise book in the other, because that is how she has done her money since her NYSC days.
She does more than spend as things come. She writes down the exact figure that entered her account, then gives every single naira a name before she touches a kobo of it. Rent gets its share, food gets its share, her mother's monthly upkeep gets its share, transport, data, that small contribution to the thrift group, even the ₦5,000 she sets aside for owambe surprises. By the time she finishes writing, the money on paper and the money in her account should match exactly. Nothing floating about unclaimed, nothing left to guess.
That is zero based budgeting. It is not about having zero money left in your account. It is about having zero money left unplanned. Every inflow gets an assignment, so at the end of your planning, income minus all your allocations equals zero, and not since you are broke, but because every naira already has a job waiting for it.
Someone in London sending £200 home each month can use the same approach. Instead of just wiring money and hoping it stretches, they sit down with whoever manages it in Lagos and decide exactly how much goes to school fees, how much to light bills, how much to their sister's shop stock, before the transfer even leaves the UK account.
This is different from just having a rough budget in your head, where you spend on rent and light and food and whatever is left becomes your free for all fund. Zero based budgeting refuses to leave a free for all fund. Even your fun money gets planned, so spending it later carries no guilt, because it was always meant to be spent that way.
Chidi earns ₦180,000 a month. Under zero based budgeting, he assigns rent ₦60,000, food ₦40,000, transport ₦15,000, data and airtime ₦8,000, savings ₦30,000, church and family support ₦20,000, and personal fun money ₦7,000. That totals exactly ₦180,000, leaving nothing unaccounted for.
Questions people ask
Does zero based budgeting mean I should spend everything I earn?
No. It means you plan everything you earn, and savings or investments can be one of the categories you assign money to, just like rent or food. Zero at the end of planning refers to nothing left unassigned, not nothing left in your pocket.
Is zero based budgeting only for people with a fixed salary?
Not at all. Someone with irregular income, like a trader or a freelancer, can still use it each time money comes in, deciding on the spot how that particular sum will be divided among needs, savings and obligations.
What happens if my expenses change halfway through the month?
You simply adjust another category to absorb the difference. If transport costs more this week because of fuel prices, you move a little from your fun money or eating out budget so the whole plan still balances to zero.
