What is a Budget Calculator
A budget calculator (also called a budget planner) helps you compare your monthly income against your expenses. By organizing spending into categories (like rent, groceries, utilities, and subscriptions), you can quickly understand where your money goes and how much is left for savings or goals.
Income vs. Expenses
See total expenses and remaining balance instantly to keep your plan realistic.
Category clarity
Add multiple expense categories so your budget reflects real life—not a generic template.
Better decisions
Spot overspending early and make quick adjustments before the month ends.
