About
The Budget Planner applies the popular 50/30/20 budgeting rule to your monthly take-home income. It instantly shows you how much to allocate to needs (50% — rent, utilities, groceries, insurance), wants (30% — dining, entertainment, subscriptions, hobbies), and savings/debt repayment (20% — emergency fund, investments, loan payoff). Enter your actual spending in each category to compare against the target and see which buckets are over or under budget. All calculations run locally in your browser.
How to use
- 1 Enter your monthly take-home (after-tax) income.
- 2 The tool shows the 50/30/20 target amounts for needs, wants, and savings.
- 3 Enter your actual spending in each category to see your budget variance.
- 4 Green means under budget; red means over budget.
- 5 Adjust your spending to bring each category within target.
- What is the 50/30/20 budgeting rule?
- The 50/30/20 rule, popularised by Senator Elizabeth Warren in her book "All Your Worth", divides your after-tax income into three buckets: 50% for needs (rent, utilities, groceries, minimum debt payments, insurance), 30% for wants (dining out, entertainment, subscriptions, hobbies), and 20% for savings and debt payoff (emergency fund, investments, extra loan payments). It is a simple framework to balance present enjoyment with future security.
- What is the difference between needs and wants in the 50/30/20 rule?
- Needs are expenses required for basic survival and financial obligations — rent or mortgage, utilities, groceries, transportation to work, minimum debt payments, and health insurance. Wants are optional spending that improves quality of life but is not essential — restaurants, streaming services, gym memberships, vacations, and new clothes beyond the basics. The line can be blurry — a car may be a need for commuting but a luxury model is partly a want.
- What if I cannot save 20% of my income?
- The 50/30/20 rule is a guideline, not a strict rule. If you live in a high cost-of-living city, needs may consume 60–70% of income, leaving less for savings. In that case, prioritise any amount of savings over none — even 5–10% builds the habit and grows over time. Alternatively, look for ways to reduce wants (the 30% bucket) to free up more for savings.
