What is the average personal income in Mexico?

INEGI's 2024 ENIGH survey reported average monthly monetary income of 12,016 pesos for men and 7,905 pesos for women. That is a per-person figure, different from average household current income, which was 25,955 pesos a month because it adds up what every member of the house brings in.

Why can't I remember what I spent last month on?

Because a normal month is not five or six purchases. It is dozens of small ones that never got stored as memories. INEGI, which measures this professionally, does not ask people what they spent last month: it sends an interviewer to the home for seven days and leaves a daily booklet the person fills in on the day of the purchase.

Should I cut spending or measure it first?

Measure first. If you cut before knowing where the money goes, you cut what you remember, and what you remember are the large isolated purchases. The money you cannot account for is usually spread across small transactions that left no trace in memory.

How long do you need to track spending to understand a month?

Longer than a month. A single period cannot tell the normal from the exceptional: pay periods are not spent the same way, and some months arrive with annual costs on top, like insurance or the holidays. Two or three consecutive months start to show a pattern; one on its own can mislead in either direction.

How to manage your money on 20,000 pesos a month

There is margin at this income. The margin is also the part of the month you will not remember.

August 13, 2026 5 min read

On 20,000 pesos a month the problem stops being arithmetic. The necessities fit, there is margin left over, and on the 30th you still cannot say where it went: there is no big purchase to blame, there are forty small ones you cannot name. Organizing your personal finances at this income is mostly a tracking problem, not a cutting problem.

On 20,000 pesos you are competing with a whole household

Earning 20,000 pesos a month puts you well above the individual average. INEGI's 2024 ENIGH survey measured average monthly monetary income at 12,016 pesos for men and 7,905 pesos for women.

The comparison that matters is a different one. Average current income for a Mexican household was 25,955 pesos a month, counting everyone who lives there. On 20,000 you alone bring in 77 % of what a full house brings in, which is why the money stretches further than headlines about the cost of living suggest.

It stretches. That is where the problem starts.

The margin is the part you will not remember

You can recite your fixed costs right now without opening anything: rent, electricity, water, internet, phone, transport, two or three subscriptions. Five to eight items, adding up to a number you know fairly precisely.

The margin does not work that way. If 6,000 pesos are left after the fixed costs and your typical purchase is around 150, that margin is not one expense. It is forty transactions spread across thirty days, made in a hurry, out in the street, none of them worth a second thought.

One 6,000-peso expense

You remember it effortlessly. The day, the reason, all of it.

Forty 150-peso expenses

Exactly the same money. You cannot name ten of them.

Both bars are 6,000 pesos. The top one leaves a memory; the bottom one leaves forty gaps, and it is the shape real monthly spending takes.

That is why at this income the question "where did my money go?" almost never has a big answer. The answer is a long one.

Why can't you reconstruct the month from memory?

Reconstructing a month of spending from memory is a task INEGI does not even attempt. When the institute wants to know what Mexican households spend on, it does not ask them what last month cost. It sends an interviewer to the home for seven days and leaves a booklet the person fills in on the same day they buy something.

1
An interviewer in your homeSeven days of visits to the same dwelling.
2
A daily spending bookletFilled in by the person, on the day of the purchase.
3
Separate questionnairesFor what does not happen daily: income, housing, large purchases.

What it takes to measure one household's spending for a single week. The 2024 ENIGH did it across 105,718 dwellings.

If that is the machinery a statistics agency needs to capture seven days, expecting yourself to reconstruct thirty on the 30th was never reasonable. And the failure is not evenly distributed: what gets lost are the small repeated transactions, which are exactly the ones the margin is made of. On why tracking by hand does not survive either, we wrote separately.

The short version: your memory is not the problem. The purchases that make up your margin were never stored as memories, because not one of them was important enough to earn it.

Track before you cut

The default advice at this income is to cut, and it always arrives before the information does. That is backwards. Cut without measuring and you cut what you remember, and what you remember are the large isolated purchases, which are rarely the problem.

A measured month changes the conversation. It stops being "I spend a lot on stuff" and becomes a number with a name: this much on eating out, this much on transport, this much in a category you did not know you had. You can decide on a number like that, and the decision is usually smaller and easier than you feared.

That is the actual work on 20,000 pesos a month. You do not need to tighten. You need to see.

What one measured month will not tell you

A month is not a pattern. The first half of the month is not spent like the second, and some months land with annual costs on top: insurance, car tax, December. Measuring thirty days and drawing firm conclusions is the fastest way to convince yourself of something false, in either direction.

Two or three months in a row and the shape appears. With one, all you have is a month.

The problem also changes with income. On 10,000 pesos a month the margin is so thin that arithmetic rules everything, and on 30,000 there stops being any signal to warn you at all.
