Finance sounds like a subject you need a degree for. It is not. Finance is simply how money moves: what comes in, what goes out, and what is left over.

The three numbers

Almost every money decision comes back to three numbers: what you earn, what you owe, and what you keep.

Example. A household brings in $5,000 a month and spends $4,400. The $600 left over is the only money available to build savings or pay down debt. Everything else is already spoken for. A shop on Golf Road works the same way with different words: sales in, costs out, cash left.

Income

Money coming in: wages, a pension, benefits, rent from a property, sales in a business. The useful number is take-home pay, after tax and deductions, because that is what actually arrives.

Spending

Most spending falls into two buckets. Fixed costs stay the same each month: rent or mortgage, insurance, a car payment. Variable costs move: groceries, fuel, eating out. Fixed costs are hard to change quickly, which is why a big fixed cost has a long shadow.

Debt

Debt is borrowed money you pay back with interest. Not all debt is the same. A mortgage at under 7 percent buys an asset that may hold its value. A credit card at 24 percent buys a dinner you already ate. The interest rate tells you how expensive the borrowing is; the term tells you how long you carry it.

Saving

Saving is money set aside and easy to reach. Most guidance suggests building three to six months of essential costs before investing, because an emergency fund is what stops a surprise becoming a credit card balance.

What this means for you

• Work out your three numbers once. Earn, owe, keep. Most people have never written them down.
• Attack the highest interest rate first. It costs you most for every month it stays.
• Build the emergency fund before the investment account.
