Personal bookkeeping: how to keep your household accounts
Personal bookkeeping means keeping your household's money records in order: what comes in, what goes out, where the money is and what is owed. You don't need accounting training or a business. It applies a simple idea that companies take for granted to your own home: if you don't record it, you don't know it.
An expense tracker answers one question: what do I spend my money on? Personal bookkeeping answers more of them. How much do we have in total? What payments are coming this month? Do our numbers match the bank's? Who owes what to whom?
The four things worth recording
1. All your accounts. Every place that holds money or debt: everyday and savings accounts, cards, cash, loans. Leave one out and the numbers will never add up.
2. All your transactions. Everything in and out, with its date, amount and account. It sounds like a lot of work, but most of it is already at your bank.
3. A category for each expense. This is what turns a long list into information. Keep them few, and use tags or notes for one-offs, such as a particular trip.
4. What's coming. Rent, bills, insurance, pay. Knowing what will happen avoids surprises, especially at the end of the month or when an annual payment arrives.
A routine you can keep up
What separates useful books from an abandoned file is the routine. This one doesn't take long:
Every week, ten minutes. Download or review your transactions, assign any missing categories and note anything paid in cash.
Every month, half an hour. Do three things: check that your balances match the bank's, look at what was spent by category against what you planned, and review next month's payments.
Every year, an afternoon. See what has changed, review insurance and subscriptions, and calculate your net worth.
The step almost everyone skips: reconciling
Reconciling means checking that your records match your bank statement. It's what makes your books reliable, and it's also the step people most often skip.
Here's how it works:
- Pick a date and take your bank's balance on that day.
- Compare each line of the statement with your own records and tick it off.
- Anything left unticked is something forgotten, a duplicate or a mistake.
- When the balance matches, that period is closed and you leave it alone.
A small difference can seem unimportant, but it usually hides something: a charge you can't place, a duplicated bill or an expense you never recorded. There's more on this in a balance you cannot explain.
If the accounts belong to two or more people
When several people share expenses, everyone should see the same numbers. Agree which accounts are shared, who records what and when you'll review them together. A short session each month helps you talk about figures rather than impressions.
If someone pays a shared cost up front, record it as a debt between you rather than trying to remember it later.
What to keep your books in
A notebook is enough to start. A spreadsheet gives you more: our guide on setting up an expense tracker has the steps. The limit appears with several accounts or several people, because reconciling by hand in a spreadsheet is slow.
Abacova is built for this work. You create an account for each place you keep money, import your bank's file and let rules sort what repeats. It has a reconciliation page that checks an account against a real statement: what matches is locked and what doesn't stands out. You can enter planned payments, which feed the balance forecast, and invite other people into your organization to share the same accounts. How many people can share it depends on the plan: see the pricing page.
Where to start
Don't try to rebuild the whole year. Pick a start date, note each account's balance on that day and record only what comes after. In a month you'll have your first full review, and you'll know more about your money than you do today.
