How to Make a Budget
Set up a monthly budget in about 30 minutes. Total your income, list your bills, sort last month's spending, and set limits you can keep.
We avoided budgeting for years because it sounded boring and restrictive. Like putting your money on a diet.
It is really more like giving your money a job. You decide where it goes instead of wondering where it went at the end of every month.
You will end up with a written monthly budget built from what you really spend. It takes about 30 minutes to set up and 5 minutes a week to keep current, and it needs no app, no spreadsheet formulas, and no cash envelopes.
Your bank and credit card statements from the last month. Look for a statements or download option on your bank's website, which usually offers PDFs or CSV files. A calculator, spreadsheet, or even a notebook. About 30 minutes of honesty with yourself about where your money actually goes.
Calculate your total monthly income
Add up everything you bring in after taxes each month. Your primary salary or wages (the amount deposited, not the gross), any side income, regular freelance payments, and any other consistent sources. If your income varies month to month (freelancers, contractors, commission-based workers), use the average of the last 3 months. If the variation is extreme, use your lowest recent month as the baseline. You can always allocate extra money from good months toward savings or debt. Using an inflated average leads to overspending in lean months.
List all fixed monthly expenses
These are bills that hit every month at roughly the same amount, such as rent or mortgage, utilities, car payment, insurance premiums, loan payments (student loans, personal loans), phone bill, and internet. Go through your last bank statement line by line. Note your subscriptions (streaming, gym, software) while you are there. They are easy to miss, because they bill automatically and never prompt you to approve them again, and step 4 counts them as wants rather than fixed bills. Add all of these up. This is your non-negotiable baseline. These get paid first, every month, no exceptions.
Track your variable spending from last month
Go through your bank and credit card statements and categorize every other transaction. Common categories are groceries, dining out (restaurants, takeout, coffee shops), gas and transportation, entertainment, clothing and shopping, personal care, gifts, and miscellaneous. Do not judge the amounts. Just categorize honestly. This is the data-gathering phase. You need to know what you actually spend, not what you think you spend.
Good to know: Check these three categories first, because each arrives as a stream of small charges rather than a few large ones. Dining out including coffee and takeout. Subscriptions billed automatically. Low-value online orders that seem trivial individually.
Apply the 50/30/20 framework
The 50/30/20 split was popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth, and it is a starting point to measure against. Needs (housing, food, transportation, insurance, minimum debt payments) should be around 50% of your after-tax income. Wants (dining out, entertainment, hobbies, subscriptions, shopping) should be around 30%. Savings and extra debt payments should be around 20%. If your needs take more than 50%, as they can where housing is expensive, take the difference out of wants before you touch savings. The framework gives you a starting point for whether your spending is roughly balanced.
Set realistic category limits
Based on your actual spending data and the 50/30/20 framework, assign a monthly dollar limit to each category. Be honest with yourself. If you spent $400 on dining out last month, budgeting $100 for next month will fail. Start by cutting 10 to 20% from problem areas. Move gradually toward your target over 2 to 3 months. Also build in a buffer category of $50 to $100 for things you forget or cannot predict.
Account for irregular expenses
List every cost that does not come monthly, such as car repairs, annual insurance premiums, holiday gifts, medical copays, home repairs, and annual subscriptions. They are easy to leave out of a monthly budget for exactly that reason. Estimate the annual cost of each. Divide that total by 12. Set aside that amount every month into a separate savings account or budget category. When these expenses hit, the money is already there. This step turns the predictable "emergencies" into planned spending.
Review and adjust weekly
Check your spending against your budget once a week. It takes about 5 minutes. Look at how much you have spent in each category versus the limit. If you are halfway through the month and already at 80% of your dining out budget, you know to cook at home for the rest of the month. This weekly check prevents the end-of-month surprise. Adjust your category limits after 2 to 3 months of data.
Put the 5-minute weekly check from step 7 in your calendar now, and plan to rework your limits after month three, when you are working from real numbers instead of estimates. If you go over in a category, move money from another category for the rest of the month instead of abandoning the budget, and see the first FAQ below if it keeps happening. Once the budget holds steady, our guide on how to save money covers where to send the 20%.
Questions we get asked about this
Answers from experience, not a textbook.
Either the limit is unrealistic for your lifestyle, or you need to address the spending habit. First, raise that category and lower another so the total stays the same. If nothing can give, make a structural change. Meal prepping cuts grocery and dining costs. Carpooling reduces gas. Canceling unused subscriptions frees up money. If you overspend for 3 months straight despite trying, the limit needs to go up and something else needs to go down.
No. A spreadsheet or even pen and paper works fine. If you prefer an app, YNAB (You Need A Budget) is built for zero-based budgeting, though it is a paid subscription. If you used Mint, note that Intuit shut it down in March 2024 and moved its users to Credit Karma. Credit Karma tracks spending from your linked accounts, but Intuit says it does not let you set monthly or category budgets, so it is a tracker rather than a budgeting tool. Whatever you use, what keeps the budget working is the weekly check in step 7.
Use the approach from step 1. Average your last 3 months, or if your income swings a lot, budget on your lowest recent month. In months where you earn more, put the excess toward savings, debt, or a buffer fund. A two-account system smooths the swings. Put all income into Account A. Every month, you transfer a fixed "salary" to Account B, which is what you budget from. Account A builds up a buffer over time that smooths out the lean months.
Use a hybrid. Joint expenses (rent, utilities, groceries, shared subscriptions) go into a shared budget, funded in proportion to each partner's income. Each partner also keeps a personal spending allowance with no questions asked. Agree on the shared categories and limits together. The personal allowance keeps individual spending choices out of the shared budget.
The common rule of thumb is 3 to 6 months of essential expenses (rent, food, insurance, minimum debt payments), though the CFPB deliberately declines to set a fixed figure and suggests sizing the fund against the unexpected expenses you have actually had. If your job is stable and you have other safety nets (family, spouse with income), 3 months is fine. If you are self-employed or in an unstable industry, aim for 6 months. Build this gradually. Even a small starter fund of a few hundred dollars can stop a minor emergency from landing on a credit card.
