The January money reset: 5 numbers to write down before the year starts
Skip the resolutions. Write down five numbers in January — net worth, monthly essentials, months of safety, debt-free date and savings rate — and check them once a month.
Money resolutions fail for the same reason gym resolutions do: they are intentions without a measurement. “Save more” and “get on top of things” have no number, so there is nothing to check in March, and by March they are gone.
A reset that lasts is smaller and more boring. Five numbers, written down in the first week of January, looked at again once a month. Each one takes a few minutes to work out and each one answers a question you will otherwise keep asking yourself all year.
1. Net worth — where you actually are
Everything you own minus everything you owe: account balances, savings, investments, the value of the car if you would sell it, minus cards, loans, overdrafts and what is left on the mortgage.
It is a scoreboard, not a verdict. A negative number in January is normal for many households; what matters is the direction by December. Write it down, date it, and resist the urge to check it weekly — monthly is the right rhythm for a number that moves slowly.
2. Monthly essentials — what life costs
The bills you must pay even in a bad month: housing, utilities, food at a normal level, transport, insurance, minimum debt payments, childcare. Not what you spend — what you must spend.
Say it comes to $3,200. This number is the unit for the next two: it tells you how long you can last without income and how big a safety net needs to be.
3. Months of safety — how long you could last
Cash you can reach within days, divided by monthly essentials:
Months of safety = easy-access savings ÷ monthly essentials
$4,800 ÷ $3,200 = 1.5 months. Three to six months is the usual target — nearer three with a stable job and two incomes, nearer six when you are self-employed or the only earner. We worked through the ranges in how much emergency fund you need. If you are under one month, this is the first goal of the year, ahead of investing and ahead of overpaying cheap debt.
4. Debt-free date — when the expensive debt ends
For each card and loan with a rate above a few percent, the month it will be paid off at your current payments. The latest of those dates is your debt-free date.
If there is no date because the balance barely moves, that is the most useful thing you will learn all January. Pick an end month, compute the payment that reaches it, and make that payment part of the budget from the first paycheck of the year.
5. Savings rate — how fast the rest is changing
The share of take-home pay that goes to saving, investing or extra debt payments each month:
Savings rate = (saved + invested + extra debt payments) ÷ take-home pay
$600 out of $4,500 is 13%. It is the one number that predicts next year’s numbers one to four. Moving it by five points — often through one or two recurring costs you no longer use — changes the whole picture over a year.
One page, twelve check-ins
Write the five numbers on one page with January’s date. On the first weekend of each month, update them in ten minutes and look at the direction, not the level:
- net worth going up;
- essentials steady or down;
- months of safety growing towards three;
- debt-free date not moving later;
- savings rate holding.
That is the whole system. No new app, no forty-category budget — the detailed budget can come later if the numbers say you need it. Many households find that the five numbers alone change what they do, because for the first time the question “are we doing okay?” has an answer.
The Personal Finance Starter is built for exactly this: a net worth sheet, debts with their payoff dates, subscriptions to cut, and one monthly page with the five numbers, what changed since last month, and three tasks for the month ahead.
