In short
Pick 8 to 12 spending categories, then get every expense into one place — log it as you spend, or import your bank and card statements once a week. Give the big categories a monthly budget and check once a month whether you saved and where the money went.
- Fewer categories, tracked every week.
- Import statements instead of typing everything.
- The monthly check is where it pays off.
Step 1: pick a few categories
Too many categories and you’ll give up. Start with around ten: housing, utilities, groceries, dining and drinks, transport, shopping, health, subscriptions, fun and other. You can split one later if it gets too big to understand.
Step 2: get every expense in
There are three ways, and most people mix them:
- Log as you go — a few seconds after each purchase. Best for cash.
- Import statements — download the CSV, OFX or QFX file from your bank’s website once a week.
- Link your bank — automatic, but it means sharing your banking access with a third party.
Don’t forget credit cards: most spending goes on them, so their statements matter as much as your chequing account.
Step 3: track income too
Expenses alone don’t tell you whether you’re okay. Record paycheques and other money in, so you can see what’s left over each month — that number is what actually changes your finances.
Step 4: give categories a budget
Once you’ve tracked a month or two, you’ll know what’s normal. Set a monthly limit on the categories that drift — usually groceries, dining and shopping. If you want a starting split, try the 50/30/20 budget calculator.
Step 5: read the month
Once a month, ask three questions: Did I save anything? Which category was biggest? What surprised me? Ten minutes of that is worth more than perfectly categorised receipts.
