Formula / Methodology

Monthly Surplus = Total Income − Total Expenses
Savings Rate (%) = (Surplus ÷ Income) × 100
Annual Savings = Monthly Surplus × 12

50/30/20 Rule:
  50% → Needs (housing, food, utilities)
  30% → Wants (entertainment, dining)
  20% → Savings & debt repayment

The 50/30/20 rule is a popular budgeting framework. A positive surplus means you are living within your means; a negative figure signals overspending that needs attention.

Understanding Your Results

Monthly Surplus/Deficit The amount left over (or short) after all expenses are paid. A surplus is money available for savings and investments; a deficit means you are spending more than you earn.

Savings Rate % The percentage of your income that you are saving each month. Financial advisors generally recommend a savings rate of at least 20% for long-term financial security.

Expense Breakdown The doughnut chart shows how each expense category compares to your total spending, making it easy to spot categories where you may be overspending.

Frequently Asked Questions

What is the 50/30/20 budget rule?

A simple, globally-applicable framework popularised by Senator Elizabeth Warren: 50% of after-tax income to needs (housing, food, utilities), 30% to wants (entertainment, dining, hobbies), 20% to savings and debt repayment. Adjust ratios based on cost of living — high-rent cities often need 60/20/20.

How much should I save each month?

Aim for at least 20% of net income. If you're starting late or want early retirement, push to 30–50%. Even 10% saved consistently from age 25 produces a meaningful retirement corpus thanks to compounding.

What is an emergency fund and how much should it hold?

A cash buffer for unexpected events — job loss, medical bills, urgent repairs. Standard guidance: 3–6 months of essential expenses for stable employment, 6–12 months for self-employed or single-income households. Hold it in a high-yield savings account or money-market fund.

How can I cut expenses effectively?

Focus on the "big three" — housing, transport, and food — which together account for 60–70% of most budgets. A 10% cut in housing or transport beats months of skipping coffees. Audit subscriptions quarterly; many people pay for services they no longer use.

Important Note

Review your budget at least once a month and update figures whenever your income or expenses change. Regular review is the single most effective habit for staying on track — small adjustments early are easier than large corrections later.
