The 50/30/20 Budget: Calculator and How to Use It

Disclosure: VaultFlow is ours. The advice works with any app, or with pen and paper.

• Use take-home pay, not salary.
• Needs are what you’d pay even in a lean month.
• If needs are over 50%, cut wants first.

What counts as what

• Needs (50%): rent or mortgage, utilities, groceries, insurance, transit or car, minimum debt payments.
• Wants (30%): restaurants, takeout, shopping, streaming, travel, hobbies.
• Savings & debt (20%): emergency fund, TFSA/RRSP, extra payments on cards and loans.

When the numbers don’t fit

In expensive cities, rent alone can pass 50%. Then trim wants to keep savings going — 60/20/20 is still a plan. The rule is a starting point, not a test.

Common questions

What is the 50/30/20 rule?

50% of take-home pay for needs, 30% for wants and 20% for savings and debt.

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

Net — your take-home pay after tax and deductions.

What if my rent is more than 50%?

Cut wants first to protect savings; adjust the split to what’s realistic.
