Budget Planner Calculator

Use this budget planner to turn monthly income into a realistic spending plan. Start with the default allocation, then adjust housing, food, transport, utilities, savings, and other categories until the numbers match your real priorities and obligations.

How to Use

1 Enter your total monthly take-home income.
2 Adjust the percentage for each spending category using the sliders or input fields.
3 The percentages default to a common budgeting framework (30/15/10/10/20/15).
4 View the dollar amount allocated to each category and your remaining balance.
5 Aim for the total to equal 100% with some going to savings.
6 Test a few versions so you can see where a tighter or more aggressive savings plan becomes realistic.

Formula

Category Amount monthly_income x (category_pct / 100)
Total Expenses sum of all category amounts
Remaining monthly_income - total_expenses

Example: $5,000 Monthly Income

With $5,000 of monthly take-home income and the default percentages: Housing = $1,500 (30%), Food = $750 (15%), Transportation = $500 (10%), Utilities = $500 (10%), Savings = $1,000 (20%), and Other = $750 (15%). Total allocated = $5,000, so the remaining balance is $0.

Why It Matters

A budget is where financial goals become operational. When you assign income to categories before the month starts, it becomes easier to protect savings, catch overspending early, and decide which expenses should be cut first if cash gets tight.

Frequently Asked Questions

What is the 50/30/20 budget rule?
The 50/30/20 rule suggests allocating 50% of income to needs (housing, food, utilities), 30% to wants (entertainment, dining out), and 20% to savings and debt repayment. It is a simple starting framework for budgeting.
What percentage of income should go to housing?
Financial experts generally recommend spending no more than 30% of your gross income on housing. Some suggest 25% or less of take-home pay for more financial flexibility. In high-cost areas, this may be difficult to achieve.
How much should I save each month?
A common recommendation is to save at least 20% of your income. This includes emergency fund contributions, retirement savings, and other financial goals. If you cannot save 20% immediately, start with what you can and increase gradually.
Should debt payments count as expenses or savings?
Minimum debt payments usually belong in your spending plan, often under housing, transport, or other fixed costs depending on the debt. Extra debt payoff can be tracked as part of savings goals if you want to treat it as intentional wealth building.
What if my percentages add up to more than 100%?
If your total exceeds 100%, you are allocating more than your income, which means you are running a deficit. Look for categories where you can reduce spending, or consider increasing your income to balance your budget.
How do I budget with irregular income?
Base your plan on a conservative income estimate, such as the lowest typical month or a multi-month average. Cover essentials first, then assign extra income to savings, debt payoff, or variable categories only after the money actually arrives.
