I used YNAB for six months. I went in skeptical — another budgeting app, another subscription, another way to feel guilty about money. I came out with a different relationship to my finances and, separately, an opinion about the tool itself.
Both are worth writing about. They are not the same thing.
YNAB’s core idea is older than the app. Give every unit of money a job. Income comes in; you assign it to categories until nothing is unassigned; you spend out of those categories. Income minus assignments equals zero. Hence “zero-based.”
The act of assigning money — not budgeting it in the abstract, but actually deciding right now what each euro is for — is the thing that changes how you spend. After a few weeks I started making decisions about my money before I made the purchase. That’s the part nobody who hasn’t done it believes.
The percentage rules — 50/30/20 and its cousins — collapse on contact with reality. They tell you how to split a paycheck in the abstract. Zero-based budgeting tells you what to do with the €127.84 actually sitting in your current account on a Tuesday.
YNAB markets four rules. I’ll rank them by how useful they actually were:
Rule 2 (Embrace your true expenses). The most underrated. The idea that you should set aside money for car insurance every month — not the month it’s due — turned out to be the financial equivalent of brushing your teeth. Quietly transformative.
Rule 1 (Give every dollar a job). Where the discipline lives. The hardest one to keep doing when you’re tired.
Rule 3 (Roll with the punches). The forgiving one. The first time you go over on groceries and just move money from another category, you realise that budgeting is not about being perfect, it’s about staying current with reality.
Rule 4 (Age your money). Useful as a long-term metric but not actionable day-to-day. I checked it once a month and otherwise ignored it.
Not what I expected.
The method is the product, but you still use the app every day. Six months in, three frictions kept coming up:
Multi-currency. YNAB is fundamentally a single-currency app. If, like a lot of Europeans, you have a USD savings account, a GBP card, and a EUR salary, you live in a kludge. Either you keep separate budgets per currency and lose the combined view, or you convert everything to one currency and watch your “totals” drift every time the FX rate moves.
Bank sync. Outside the US, YNAB does not sync directly with most banks. You import CSVs or use third-party glue (Banktivity, MoneyDance, Macroenter). It works. It is not pleasant. I lost about ten minutes a week to it.
Price. ~€110/year for what is, technically, a constrained spreadsheet. The method is worth it. The price feels less aligned with the actual value the further you get from launch-era pricing.
The mobile app. YNAB’s mobile experience is a courtesy, not a primary surface. Increasingly, that’s the wrong bet. I want to add a transaction on the bus.
None of these would make me regret the six months. They are also reasons I started looking around.
Most of what I learned in six months of YNAB had nothing to do with YNAB:
These are method facts, not app facts. They survive any tool change.
We’re building Cooperae Budget because the method works and the apps available in Europe — including YNAB — don’t quite fit how people here actually hold money. Multi-currency by default. PSD2 done properly. The same zero-based discipline, with the parts of YNAB that are tied to its US roots taken out.
If you’ve done your own six months of YNAB and have your own list, we’d love to hear it — hello@cooperae.com.
