Budget, Debt & Savings

Start with a budget that survives real life

A budget only works if you can actually follow it, so start by tracking what you already spend for a month before you change anything. Then try the 50/30/20 rule as a starting point: about 50% of your take-home pay on needs (rent, bills, food, transport), 30% on wants, and 20% on savings and extra debt payments. On $4,000 a month take-home, that means $2,000 for needs, $1,200 for wants and $800 towards your future. The exact split matters less than the habit — and paying yourself first, by moving the savings out on payday before you can spend it, beats relying on willpower at the end of the month.

Clearing debt: snowball vs avalanche

If you have several debts, the order you pay them off matters. The avalanche method targets the highest interest rate first, which saves the most money: clearing a 24% credit card before a 6% loan is the mathematically cheapest route. The snowball method clears the smallest balance first, which costs a little more in interest but gives you quick wins that keep you going. People who feel progress stick with a plan longer, so the best method is usually the one you will actually finish. Either way, pay more than the minimum whenever you can: minimum payments are designed to stretch a debt out, not to clear it.

Compound growth does the heavy lifting

Compound interest means your returns earn returns of their own, and time is the ingredient that matters most. The rule of 72 gives a quick sense of it: divide 72 by your annual return to find how many years it takes your money to double — about 10 years at 7%. Put $200 a month into an account earning 7% a year and after 30 years you would have about $244,000, even though you only paid in $72,000. Start ten years later and the same monthly amount reaches only about $104,000 — starting early is worth more than saving twice as much later.

Set a savings goal backwards

The easiest way to save for something specific is to work backwards: divide the target by the number of months until you need it. A $6,000 emergency fund in a year means $500 a month; a $1,200 holiday in six months means $200 a month. Keep the money in a separate account so it is out of sight, automate the transfer for payday, and treat the goal like a bill you owe yourself. Our savings goal calculator works out the monthly amount for any target and date, including the interest your savings earn along the way.
