How the monthly cost calculator works
This calculator helps you take control of your finances by comparing your monthly income against your total monthly expenses across key categories: housing, utilities, groceries, transport, insurance, entertainment, savings, debt, and more. It calculates your savings rate, shows where you’re overspending, and gives you a clear picture of your financial health.
Enter your monthly income and fill in each expense category below. The calculator will instantly show your total monthly costs, budget breakdown, and a comparison of your spending against recommended benchmarks.
Step 1: Income & Basics
Understanding Your Budget
A healthy budget typically follows the 50/30/20 rule: 50% for needs, 30% for wants, and 20% for savings & debt repayment. This calculator helps you see how your spending aligns with these benchmarks.
Step 2: Monthly Expenses
Smart Spending Tips
Try to keep housing costs under 30% of your income, and aim to save at least 20%. If you’re overspending in any category, look for small adjustments — they add up over time.

Frequently Asked Questions
What is a monthly cost calculator?
A monthly cost calculator helps you track and analyse your monthly expenses against your income. It breaks down spending by category, calculates your savings rate, and helps you identify areas where you can cut costs.
How do I calculate my monthly costs?
Add up all your fixed expenses (rent, utilities, insurance) and variable expenses (groceries, entertainment, transportation) for a typical month. Subtract this total from your monthly income to find your surplus or deficit.
What is a good savings rate?
Financial experts generally recommend saving at least 20% of your monthly income. A savings rate of 20-30% is considered excellent, while anything above 30% is outstanding.
What percentage of income should go to rent?
The general rule of thumb is to spend no more than 30% of your gross monthly income on housing costs, including rent or mortgage payments, utilities, and insurance.
How can I reduce my monthly costs?
Start by tracking all expenses to identify spending patterns. Look for subscriptions you don’t use, reduce dining out, negotiate bills, shop with a list, and consider energy-efficient upgrades to lower utility bills.
