Accounting for Life: 5 Ideas That Work Outside the Books

The Moment

Accounting taught me more about life than about numbers.

When I was studying for the CA exams, I learned accounting the way most students do. Definitions. Journal entries. Rules. The right answer in the right format. I was learning it to pass.

It took me years to notice that some of those ideas were quietly describing my own life.

Why I kept saying yes when I wanted to say no. Why small spends somehow became a much bigger number at the end of the month. Why things I had once learned became hard to use. Why my plans looked perfect on Sunday and completely different by Friday. And why something can be “working” today and still be a terrible way to live for the next five years.

That’s when accounting started looking less like a subject and more like a way of seeing.

You don’t need to be an accountant to use it. You only need five questions.

What’s Going On

At its heart, accounting is not really about numbers. It is a discipline of honesty. It makes you write down what you would rather not see — the cost you ignored, the leak you didn’t notice, the value that quietly fell, the gap between the plan and the result.

Most money and life problems start exactly there: not with a lack of information, but with a comfortable way of not looking.

So here is the one question that runs through this whole article: what would an accountant ask me about this?

One note before we start: these are analogies. Your skills don’t literally depreciate on a balance sheet, and your week is not a bank account. But the way accountants think turns out to fit ordinary human behaviour surprisingly well.

What’s Behind It

01 — Double entry: every yes has another side.

You say yes to one more meeting. The other side might be one hour less with your family.

You say yes to another weekend plan. The other side might be the rest you badly needed.

You say yes to the new phone. The other side might be three months of savings you no longer have.

You say yes to scrolling for one more hour at night. The other side is tomorrow morning’s sleep.

In accounting, an entry never exists alone. If money goes out, something else changes somewhere — and the books force you to record both sides. Life doesn’t. We are very good at recording what we receive, and much worse at recording what we give up. Economists call that second side the opportunity cost.

The second side is real even when it doesn’t come with a bill. So before your next important yes, ask: what am I saying no to? Sometimes the answer will still be worth it. That’s fine. The point isn’t to say no. It’s to see both sides before you say yes.

02 — Materiality: small things become big when they repeat.

One ₹60 chai won’t change your life. Neither will one food delivery, one subscription, one cab instead of the metro, or one “I’ll start tomorrow”.

Individually, most of these are insignificant. That’s exactly why they slip through.

In accounting, something is “material” when it is big enough to change a decision. Life has the same test — and the twist is repetition. (The amounts below are illustrations, not data.) A ₹60 chai on 22 working days is ₹1,320 a month. One ₹500 purchase is not a crisis; ten of them are ₹5,000.

And it isn’t only money. Ten minutes of scrolling is nothing — ten minutes every day for a year is more than 60 hours. One missed workout isn’t the problem; the pattern is. One avoided conversation is not a broken relationship; a habit of avoiding them can become one.

The lesson isn’t “worry about every small thing”. That’s exhausting. The lesson is: pay attention to what repeats. The chai isn’t the story. The habit is. (I wrote a whole article on the money side of this: The ₹500 Leak.)

03 — Depreciation: what you don’t use slowly becomes harder to use.

You passed the course. You framed the certificate. You felt proud for a week. Then life got busy.

Two years later, someone asks you to actually use what you learned. You still have the certificate. You still remember that you once knew it. But you don’t have the same fluency.

In the books, a machine loses a little value every year, and accountants record that honestly. As an analogy, many of us treat our qualifications like land — bought once, valuable forever. But the knowledge behind them behaves more like a machine: without use and upkeep, it slowly loses practical value — and the world notices before we do.

A large review of skill-decay research found that skills which go unused for a long time — especially more than a year — are lost to a large degree, with the size of the loss depending on the skill. Having learned something once is not the same as being able to use it today.

Your degree is an asset. So are your health, your relationships and your ability to think clearly. Assets need maintenance. The good news: unlike a machine, a human skill can often be rebuilt. Twenty minutes can reopen something you haven’t touched in years. So ask: what valuable thing in my life am I letting lose value through neglect?

04 — Reconciliation: your plan isn’t your reality.

On Sunday: “I’ll exercise five days. I’ll sleep by 11. I’ll save ₹20,000. I’ll finish the course.”

By Friday: three workouts, sleep closer to midnight, spending higher than planned, and the course still sitting at 38%. (An illustration.) Somehow the week disappeared.

Most of us respond by making a better plan for next week. That’s often the wrong first step.

Every accountant knows this feeling. The books say one thing; the bank statement says another. So you reconcile. You don’t get angry with the bank. You find the difference, and you explain it.

In a classic study, students predicted they would finish their thesis in about 34 days. Even their “worst-case” guess was about 49 days. On average, they took about 55 days — and only about 30% finished in the time they had predicted. Psychologists call this the planning fallacy.

The answer isn’t to stop planning. It’s to stop treating the plan as reality. Your plan is a guess. Your actual week is the evidence. Reconciliation is how you learn from the evidence — and the gap usually has a reason. Maybe you underestimated the commute. Maybe your evenings are less predictable than you assumed. Maybe you keep saying yes to things that eat the time you thought you had. Don’t hide the difference. Study it.

Your plan is a guess. Your actual week is the evidence.

05 — Going concern: can this way of living continue?

In accounting, “going concern” asks a basic question: can this business keep running for the foreseeable future? If not, everything else in the accounts is read differently.

We rarely ask ourselves the same thing. Is this routine working? Is this budget working? Maybe. Now ask a harder question: can I keep doing this for five years?

A routine that only works when you sleep five hours isn’t really working. A budget that only works if nothing unexpected happens isn’t robust. A fitness plan that needs two hours a day when you realistically have thirty minutes isn’t a plan — it’s a wish. A pace that leaves no room for family looks fine this month, and costs more every month after.

And it rarely happens in one dramatic moment. You get used to being tired. You get used to ordering food because you’re too exhausted to cook. You get used to postponing exercise, to missing family dinners, to saying “this is just a busy phase”. Then, one day, the busy phase becomes your life.

Something can produce a good result today and still be unsustainable. That’s why the question isn’t “Is this working?” It’s “Can this last?”

One Habit

The monthly life reconciliation.

On the first day of every month, take fifteen minutes and a notebook. Draw two columns — Planned and Actual — and fill in three lines:

Money: what I planned to spend vs what I spent. Time: what I planned to do vs what I did. One goal: where I hoped to be vs where I am.

Then write one last line: “The gap taught me ____.”

Your job isn’t to make the two columns identical. It’s to understand why they’re different. Accountants don’t reconcile because they expect the numbers to match perfectly. They reconcile because every difference deserves an explanation. Use it to understand yourself, not to punish yourself. This is my own simple reflection exercise, not a scientifically tested programme.

If fifteen minutes feels like too much, start with just the money line. One line, every month, is already more than most people do.

Your 7-Day Check

You don’t need to wait for the first of the month. Over the next seven days, try one small version of each question:

1. Double entry: before one “yes”, ask: what is the other side?
2. Materiality: take one small daily habit and multiply it by thirty.
3. Depreciation: pick one skill you haven’t used in a year. Give it twenty minutes.
4. Reconciliation: compare one plan from last week with what actually happened.
5. Going concern: look at one habit and ask: could I realistically keep this up for five years?

At the end of the week, notice which question made you pause. That’s probably the one worth keeping.

We spend years learning to record transactions, value assets, reconcile differences and judge whether a business can continue. Then we close the books — and go back to living without applying any of it to ourselves.

But our lives have entries too. Things we gain. Things we give up. Things that quietly lose value. Gaps between what we planned and what happened. Choices that look fine today but cannot continue forever.

The real balance sheet isn’t the one we prepare for someone else. It’s the one we live in. And unlike a company’s books, you don’t get to close them at the end of the year.

You have to keep living in them.

Which of these five questions has caught you out in real life? I’d like to hear it in the comments.
