How it works
Enter your total monthly income and then fill in your spending amounts for each category. The calculator instantly shows total expenses, remaining savings, and a colour-coded progress bar for each category showing what percentage of your income it consumes. Categories consuming more than 30% of income are highlighted in amber, and those above 50% in red, so you can quickly spot areas to review.
A common budgeting guideline is the 50-30-20 rule: allocate 50% of income to needs (housing, food, utilities), 30% to wants (entertainment, clothing), and 20% to savings and investments. Use this calculator to see how your current spending compares.
Common budgeting mistakes to avoid
No Emergency Fund
Without 3–6 months of expenses saved, any unexpected event forces you to break investments or take on debt. Build an emergency fund before allocating to long-term goals.
Ignoring Subscriptions
Small recurring charges (OTT, apps, gym) add up quickly. Audit all monthly subscriptions annually and cancel ones you rarely use.
Not Paying Yourself First
Invest your SIP amount on the day you receive your salary — before spending on wants. Waiting until 'whatever is left' rarely results in consistent savings.
Underestimating Irregular Expenses
Annual expenses like insurance premiums, property tax, or car servicing must be divided by 12 and included in your monthly budget to avoid surprise cash crunches.
Frequently Asked Questions
What is the 50-30-20 budgeting rule?
The 50-30-20 rule suggests allocating your take-home income as: 50% to needs (housing, food, utilities, transport, insurance), 30% to wants (dining out, entertainment, hobbies, subscriptions), and 20% to savings and investments (emergency fund, SIP, retirement). It is a simple starting framework — adjust the percentages to match your goals.
How much of income should go to rent?
A common guideline is to spend no more than 25–30% of your take-home salary on rent. Spending above this threshold strains the rest of your budget, leaving little room for savings and other needs. If your rent exceeds 30%, consider moving to a lower-cost area or increasing your income.
What is a good savings rate?
Financial planners generally recommend saving at least 20% of your net income. If you are in the early stages of your career, start with 10% and increase by 1% with each salary increment. The higher your savings rate, the faster you build wealth and achieve financial independence.
What is an emergency fund and how large should it be?
An emergency fund is 3–6 months of essential living expenses kept in a liquid, low-risk account (savings account or liquid mutual fund). It covers unexpected events like job loss, medical emergencies, or urgent repairs without derailing your investment plan. Build this first before investing in long-term instruments.
