How to track your spending in Argentina

Most personal finance advice in circulation assumes three things that don't hold in Argentina: that this month's prices are a fair basis for budgeting next month, that you deal in one currency, and that what you buy today you pay for this month.

None of the three is true here. Which is why the method matters more than the advice.

This applies whether you live here, moved here, or work remotely and get paid from abroad.

The budget isn't built once a year

A budget built in March describes March's prices. When prices move, by June your "needs" weigh more without you having changed a single habit, and the budget starts telling you that you failed when something else happened entirely.

What works here:

• Recalculate every three months, not every year. It takes ten minutes and saves you six months of numbers that mean nothing.
• Watch the trend, not the amount. If your fixed costs went from 55% to 62% of income in a quarter, that jump is the information. The absolute figure tells you nothing because everything went up.
• Keep the history. It's the only thing that later lets you tell a price rise apart from a change in behaviour.

The 50/30/20 split still helps, but as a structure rather than a target: here the percentages move on their own.

Instalments: half of next month is already decided

Buying in instalments is the norm, not the exception, and that has a concrete bookkeeping consequence: next month's statement is already partly written.

If you log the full purchase on the day you buy, that month is inflated and the next five look light. If you don't log it, it shows up on the statement by itself. Neither lets you know what you have left.

What works is logging the instalment as a recurring expense over N months, not the purchase. That way the question before buying stops being "does the payment fit?" and becomes "does it fit alongside every other instalment I already have?", which is the right one. It's covered in interest-free instalments.

Two currencies in the same month

You earn in pesos and save in dollars, or you earn in dollars and spend in pesos, or both at once. Adding the two numbers gives a total that doesn't exist.

There's one rule: log each expense in the currency it was paid in, and let the conversion lock to the day of the expense. If the app recalculates everything at today's rate, a closed month changes size every time you open it and the history becomes useless — which is exactly what you need here. The reasoning is in tracking two currencies, and the mechanism in multi-currency.

One warning worth knowing: if you buy abroad on a card in instalments, each payment arrives at a different number, because it converts at each due date. That isn't an app bug.

Money passes through many hands

Cash, bank transfers, Mercado Pago, debit, credit, and probably another wallet. The practical consequence is that no single source has your complete month: the bank can't see the cash, the wallet can't see the card, and the card can't see the transfers.

That's why automatic bank connection delivers even less here than elsewhere, and why a method that's indifferent to payment method pays off. It's covered in tracking without connecting a bank.

If you invoice

Argentina's monotributo regime has two consequences for expense tracking, and both are solved the same way:

1. Your bracket depends on what you invoiced over the last twelve months, so you need that running total at hand rather than once a year when recategorisation comes around.
2. The monthly fee and contributions are a fixed cost, not a surprise. They go in as recurring expenses.

And the most expensive part of self-employment here: setting tax money aside on the day you're paid rather than the day it's due. Covered in irregular income and separating personal and work expenses.

In one line

Recalculate quarterly instead of yearly, log the instalment rather than the purchase, record each expense in its own currency at that day's rate, and use a method that works the same for cash as for cards — because here no single source has your whole month.
