Is the 50/30/20 rule based on gross or net income?

Net, your take-home pay after taxes and payroll deductions. Splitting gross income overstates what you can spend, because the tax portion never reaches your account.

What if my needs are more than 50%?

Common in high-rent cities. Treat 50/30/20 as a target, not a law: trim the 30% wants first, keep the 20% savings protected if you can, and revisit needs (housing, insurance) over time. The split is a compass, not a cage.

Where should the 20% actually go?

In rough order: a small starter emergency fund, then high-interest debt, then a fuller emergency fund and long-term investing. The goal is for the 20% to grow, not just sit idle.

Why do I still run out of money with a "correct" budget?

Because a monthly budget hides timing. If rent and a card payment both land before payday, your balance can dip negative mid-month even though the monthly totals balance. Projecting your balance day by day catches that before it happens.

Does Wiggle Budget enforce 50/30/20?

No, it shows you reality. You set your own categories and recurring bills, and Wiggle Budget projects your balance forward so you can see whether your real split holds up over time and what is genuinely safe to spend.

The 50/30/20 budget rule: split take-home pay into 50% needs, 30% wants, 20% savings, and how to make it stick

What the 50/30/20 rule is, how to calculate your split from take-home pay, where it breaks, and how to make the 20% genuinely grow.

50% Needs

The essentials you truly cannot skip.

Typically: Rent / mortgage, Utilities & groceries, Insurance & minimum debt payments, Transport to work.

30% Wants

The life you actually enjoy, guilt-free, but capped.

Typically: Dining out & coffee, Subscriptions & hobbies, Travel & treats, Upgrades you want, not need.

20% Savings & growth

The part that builds wealth, pay it first, not last.

Typically: Emergency fund, Investing / retirement, Extra debt payoff, Big goals (home, car).

Start from take-home pay

Use your after-tax income, what actually lands in your account. The split is 50/30/20 of that number, not your gross salary.

Do the math once

On $4,000 take-home: $2,000 to needs, $1,200 to wants, $800 to savings & growth. Round to clean numbers you can remember.

Pay the 20% first

Move savings and investing the day you get paid, before spending. What is left auto-limits your wants, no willpower required.

Check it against the calendar, not the month

Bills land on different days than payday. Map them on a timeline so a big bill early in the month never pushes you negative before income arrives.
