Step 1: Start with what you take home
Budget with your pay after tax and deductions, not your salary. If you’re not sure what that is, the paycheck calculator works it out.
Step 2: See where your money goes
Look back at one or two months of bank and card statements. Most banking apps sort spending into categories for you. Don’t judge it yet: just find out what you really spend on rent, food, transport, subscriptions and eating out.
Step 3: Split it 50/30/20
| Share | For | Examples |
|---|---|---|
| 50% | Needs: what you must pay | Rent or mortgage, groceries, utilities, insurance, minimum debt payments |
| 30% | Wants: what makes life enjoyable | Eating out, streaming, travel, hobbies |
| 20% | Saving and paying off debt faster | Emergency fund, retirement, extra card payments |
Example: $4,000 a month take-home
| Part | Amount |
|---|---|
| Needs | $2,000.00 |
| Wants | $1,200.00 |
| Saving and extra debt payments | $800.00 |
| Take-home pay | $4,000.00 |
The same split at other take-home pays, a month:
| Take-home | Needs (50%) | Wants (30%) | Saving (20%) |
|---|---|---|---|
| $2,500 | $1,250 | $750 | $500 |
| $3,500 | $1,750 | $1,050 | $700 |
| $4,500 | $2,250 | $1,350 | $900 |
| $6,000 | $3,000 | $1,800 | $1,200 |
| $8,000 | $4,000 | $2,400 | $1,600 |
If the numbers don’t fit
In expensive cities, rent alone can take half your pay, and that’s common. Treat 50/30/20 as a guide, not a test:
- Cut wants first. They’re the easiest to change, and small subscriptions add up.
- Housing is the biggest lever. A roommate or a cheaper place does more than skipping coffee.
- Save something, even 5%. The habit matters more than the amount at first.
Plan for bills that don’t come every month
Car insurance paid twice a year, holidays, birthdays, car repairs and yearly subscriptions are what usually break a budget. Add up what they cost in a year, divide by 12, and move that amount into a separate savings account each month. A $1,200 yearly insurance bill becomes $100 a month, and it’s there when the bill arrives.
Other ways to budget
- Zero-based budget: give every dollar a job before the month starts, so income minus spending and saving comes to zero. It takes more time but shows exactly where everything goes.
- Pay yourself first: move your savings out on payday and spend the rest freely. It suits people who don’t want to track every purchase.
- Envelopes: set a fixed amount for each spending category, in cash or separate accounts, and stop when it’s gone.
Make it automatic
- Set an automatic transfer to savings for the day after payday.
- Put fixed bills on autopay so you never pay late fees.
- Give yourself a set amount for spending, and check in once a month.
Try your own numbers in the budget calculator, which starts from your take-home pay and shows the 50/30/20 split next to what you really spend.
What to do with the 20%
Use the saving share in this order: a small emergency fund first, then enough in your 401(k) to get the full employer match, then paying off high-interest debt with the debt payoff calculator, then building the emergency fund up to three to six months and saving more for retirement.
