Deliberate Bill Calendars
bills, set against payday
A calendar tells you when each bill is due. It doesn't tell you whether the money is there that day. Every month has a low point, usually the few days before pay lands, and the bills that fall in it decide whether you scrape through or overdraw. Lay the bills against your paydays, find that low point, and move the one bill that causes it.
- Moderate
- High impact
- Learn it: 2-4 weeks
- One phone call per bill moved
A fictional month: £1,500 on the 1st, £1,650 pay on the 25th, about £10 a day on the card, five bills. Same bills, same pay, same total. Only one due date changed.
The method
Find the low point, then move what lands in it.
-
Mark the paydays
The days money actually lands, and how much. Paid twice a month, or by two people, means two marks.
-
Lay the bills against them
Every bill on its due day, plus a rough daily figure for the card. Now the month reads as one running balance.
-
Find the low point
The lowest the balance goes, and the day it happens. It's almost always just before pay, and it's the only day that matters.
-
Move one bill
Ask the provider to move the bill that drops into the dip to a day or two after payday. One move often does the work of a bigger buffer.
-
Look again each month
Ten minutes before the low stretch: is the dip where you expect, and has anything new landed in it?
Mark pay, lay the bills, find the low point, move one bill, look monthly.
Example: Ama is paid on the 25th. Rent goes on the 1st, and their car loan and card both fall the week before payday, so most months they're overdrawn for a few days and pay for it. One call to the lender moves the car loan to the 26th. The month costs the same, and the balance never touches zero.
The payday map
Put in your pay and bills, see the month's low point.
1 · Your money in
Everyday spending is the card, cash and groceries, spread evenly over the week. On a day when a bill and pay both land, the bill is counted first, to be safe.
2 · Your bills
No bills yet. Add the first one below, or show an example.
Monthly bills only. Quarterly and yearly ones belong in a year plan, the next skill up.
3 · The month
4 · Make the call
A move only counts once the provider has made it. Ask for the new due day, and check the next bill shows it. Some providers will move a due date if you ask, and some limit how often it can change.
5 · The monthly look
Once a month, before the low stretch, open this page and check the dip. Mark the month when you have.
Your pay and bills are kept only in this browser. Nothing is sent anywhere.
The research behind it
Most overdrafts come from not looking.
Victor Stango and Jonathan Zinman studied 7,448 people in the US who let a market research firm see their bank accounts, month by month from 2006 to 2008. Roughly half never paid an overdraft fee. Among those who did, 31% of months carried one.
Running close to the edge was ordinary. Even among people who never overdrew, the balance dipped under $100 at some point in 56% of months. The difference between the two groups wasn't how often money ran low. It was whether they were paying attention when it did.
Their test of attention was a small one. Now and then the firm sent panelists a survey, and some surveys happened to ask about overdrafts. In the month someone answered one, their chance of an overdraft fee fell by 3.7 points, from a base of 30%. Each such survey in the past two years kept it 1.7 points lower, so three meant a 17% drop. A few questions about overdrafts made people look.
How they avoided the fees matters here. They didn't keep more money in the account. They made fewer card payments and cancelled automatic withdrawals, the outgoings whose timing is hardest to track. Moving a due date is the same kind of fix, made once instead of every month. That step is ours: the study measured attention and fees, not due dates, and the effect was clearest among people with less education, financial know-how or income.
The idea
Why it works.
Money in and money out run on two clocks: pay on one day, bills scattered across the rest. The total can balance perfectly over the month and still leave a few days where more has gone out than has come in. Those days are where fees happen.
Seeing the month as one running line turns a vague worry into a single date. Moving a bill a few days later, across payday, changes nothing about what you spend. It changes when, and that's often all the low point needs.
When it goes wrong
Habits that help.
- Payday moves at weekends. If pay comes early or late when the 25th is a Sunday, check the dip for that month. The day before payday can be three days long.
- Pay that varies. Use your lowest normal month, not the average. The map is for the bad month.
- Don't stack everything on payday. If pay is ever a day late, every bill moved onto it lands in the dip at once. A day or two after is safer.
- Count the card bill too. It's easy to treat it as spending, but it leaves on one day, like rent.
