Budget Builder (50/30/20)
Turn your monthly take-home pay into needs, wants and savings targets using the 50/30/20 rule or your own mix, then check it against what you actually spend and see how your savings rate maps to years of financial independence.
Your framework allocation
How each dollar of take-home pay is assigned under the chosen framework.
Actual spending vs target
Grouped by bucket. Bars above target mean that category is eating into your savings.

How this is calculated
The 50/30/20 rule (where it comes from)
The framework was popularized by Elizabeth Warren, the U.S. senator and bankruptcy-law scholar, and her daughter Amelia Warren Tyagi in the 2005 book All Your Worth. It splits your after-tax take-home pay: needs = 50%, wants = 30%, savings + extra debt repayment = 20%. The 60-10-10-10-10 variant assigns 60% to essentials and four 10% slices (this tool groups them into 60% needs, 20% savings and 20% wants for the chart).
Custom splits normalize to 100%
With a custom framework the three percentages are normalized so they always sum to 100: share = slice ÷ (needs + wants + savings). You can set them in any ratio, for example 60/20/20 for a high-cost city, and the tool rescales automatically.
Targets and savings rate
Each target is simply take-home × share. Your savings rate is the savings share of take-home pay. The hero number is your monthly savings target under the framework.
Years to financial independence (a teaser)
Using the 4% rule, your FI number is 25 × annual spending. The rough years-to-FI shown here is FI number ÷ annual savings, savings only, before any investment growth, so it is deliberately pessimistic. Notice a quirk: at a 20% savings rate this is always about 100 years regardless of income, because you save 20 and spend 80 (25 × 80 ÷ 20 = 100). Raising the savings rate is what actually moves the needle. For a proper projection with market returns, CPP and OAS, use the FIRE calculator.
Needs vs wants classification
When you enter actual spending, housing + transport + groceries is treated as needs and dining + subscriptions + other as wants. Whatever is left of your take-home pay after both is your implied actual savings. A bucket over its target is flagged so you know where the money is leaking.
The Canadian reality check
Average one-bedroom rent tops $2,000/month in Toronto and Vancouver, so housing alone can blow past 50% of take-home for many renters. That is a signal to adjust the framework, not to feel guilty. Protect the savings slice first (pay yourself first, automate a transfer on payday), then fit needs and wants to what is left.
What this doesn't model
Irregular income, annual or one-off expenses (insurance renewals, property tax), sinking funds, or the tax treatment of where you save. Convert a gross salary to take-home with the income tax calculator first, and plan the destination of your savings with the FIRE calculator.
Common questions
What is the 50/30/20 budget rule?
The 50/30/20 rule, popularized by U.S. senator and bankruptcy scholar Elizabeth Warren in All Your Worth, splits your after-tax take-home pay into 50% needs (housing, groceries, transport, utilities, minimum debt payments), 30% wants (dining, subscriptions, hobbies, travel) and 20% savings and extra debt repayment. It is a starting framework, not a law, adjust the percentages to your reality.
Does 50/30/20 work in Toronto or Vancouver?
Often not as written. Average rent for a one-bedroom runs well over $2,000 a month in Toronto and Vancouver, so housing alone can exceed 50% of take-home pay for many renters. The fix is to adjust the framework, not to feel guilty: switch to a custom split (for example 60/20/20 or 60/10/10/10/10), protect the savings slice first, and treat the needs number as a target to work toward, not a failure.
Should I budget on gross or take-home pay?
Use take-home (net) pay, what actually lands in your account after income tax, CPP, EI and any payroll deductions. Budgeting on gross salary overstates what you can spend because a large slice never reaches you. Use the income tax calculator to convert a gross salary into monthly take-home first.
How does my savings rate affect when I can retire?
Your savings rate, the share of take-home pay you keep, is the single biggest lever on financial independence. Using the 4% rule, your FI number is 25 times your annual spending. Saving 20% of take-home implies roughly a 100-year path on savings alone, while saving 30% cuts it to about 58 years and 50% to around 17 years before investment growth is even counted. Higher savings both grows the pile faster and shrinks the target.
What counts as a need versus a want?
Needs are essentials you cannot easily skip: rent or mortgage, groceries, utilities, transportation to work, insurance and minimum debt payments. Wants are lifestyle choices: dining out, streaming and subscriptions, travel, hobbies and upgrades. This tool classifies housing, transport and groceries as needs, and dining, subscriptions and other discretionary spending as wants, so you can see where a bucket is over target.
