20 Common Monthly Expenses To Include In Your Budget

Look, I’ve been helping people fix their finances for over a decade, and here’s the brutal truth: most budgets fail because people forget half the stuff they actually spend money on.

Ever wonder why your “perfect” budget explodes by month two? It’s because you treated budgeting like making a grocery list instead of planning for real life.

Trust me, I’ve seen it all. The person who budgets $200 for groceries but forgets they eat lunch out three times a week. The couple who plans for rent and utilities but completely blanks on their Netflix, Spotify, and Disney+ subscriptions. Sound familiar? 🙂

Today, we’re going to fix that. I’m walking you through the 20 most important monthly expenses you need to consider, from the obvious rent payment to those sneaky little costs that add up faster than you can say “where did my money go?”

1. Housing Expenses

Primary Housing Costs

Your housing payment is obviously the big kahuna here. Whether you’re renting or own your home, this is typically your largest monthly expense, and for good reason. Financial experts (myself included) recommend keeping housing costs under 28% of your gross monthly income.

Rent or Mortgage Payment: This one’s straightforward, but here’s what most people miss, if you’re a homeowner, budget for potential rate increases if you have an adjustable-rate mortgage. I learned this the hard way during my first home purchase.

Property Taxes: Homeowners, this is crucial. Even if your taxes are escrowed with your mortgage, understanding this cost helps you prepare for potential increases. Property values change, and so do your tax bills.

Homeowners or Renters Insurance: Don’t even think about skipping this. I’ve seen too many people learn expensive lessons when they thought they could save a few bucks here.

Housing-Related Services

Home Maintenance and Repairs: Set aside 1-3% of your home’s value annually for maintenance. Renters, you still need basic supplies and tools.

HOA Fees: Homeowners association fees are mandatory and often increase annually.

2. Utilities and Essential Home Services

Here’s where people get sloppy with their budgets. You know you need electricity, but do you account for seasonal variations?

Electricity and Gas: Your summer and winter bills can swing wildly depending on where you live. I always recommend budgeting based on your highest bills from the previous year.

Water and Sewer: Usually more predictable than other utilities, but factor in any rate increases your municipality might announce.

Internet and Cable: Let’s be real, internet isn’t optional anymore. Cable TV might be, but budget for what you actually use.

Trash and Recycling: Sometimes included in rent, sometimes separate. Either way, it’s going somewhere in your budget.

3. Transportation Costs

Vehicle-Related Expenses

If you own a car, congratulations, you’ve committed to a whole bundle of monthly costs that go way beyond your car payment.

Car Payment or Lease: The obvious one, but here’s a pro tip, if you’re planning to upgrade soon, start budgeting for that new payment now.

Auto Insurance: Shop around annually for this one. I’ve saved clients hundreds just by switching carriers with identical coverage.

Fuel: Gas prices are unpredictable, but you can estimate based on your driving habits. Track your mileage for a month to get realistic numbers.

Vehicle Maintenance: Oil changes, tire rotations, inspections, these aren’t surprises if you plan for them. Budget at least $100-150 monthly for a reliable vehicle.

Alternative Transportation

Public Transportation: Monthly passes, daily fares, if you use it regularly, budget for it properly.

Rideshare Services: Uber and Lyft costs add up faster than you think. I’ve seen people spend $300+ monthly without realizing it.

Parking Fees: City dwellers know this pain. Monthly garage fees, street parking, work parking, it all counts.

4. Food and Groceries

Essential Food Costs

Food is non-negotiable, but how much you spend is totally up to you. The USDA estimates the average family of four spends $568-1,106 monthly on groceries, but your mileage may vary.

Grocery Shopping: Track your actual spending for two months before setting this budget. People consistently underestimate food costs by 20-30%.

Dining Out: Be honest about this one. If you grab coffee three times a week and order takeout twice, budget for it. Fighting your habits in your budget is a losing battle.

Work Lunches: Even if you pack lunch most days, account for the occasional cafeteria meal or coffee run with colleagues.

Special Dietary Needs

Supplements and Vitamins: If these are part of your routine, they belong in your budget.

Special Diet Requirements: Gluten-free, organic, keto, specialty foods cost more. Budget accordingly.

5. Health and Medical Expenses

Medical Expenses

Healthcare costs are sneaky budget killers because they’re often irregular but inevitable.

Health Insurance Premiums: If you pay these directly (not deducted from payroll), they’re a major monthly expense.

Prescription Medications: These costs are predictable, so there’s no excuse not to budget for them.

Regular Medical Appointments: Co-pays for routine checkups, dental cleanings, eye exams, spread the annual costs across 12 months.

Dental and Vision Care: Even with insurance, you’ll have co-pays and deductibles.

Health Savings and FSA

HSA or FSA Contributions: These tax-advantaged accounts help with medical expenses, but you need to fund them monthly.

6. Personal Care and Hygiene

Personal Hygiene Products: Shampoo, toothpaste, deodorant, the basics add up to $50-100 monthly for most people.

Haircuts and Styling: Whether you spend $15 at Great Clips or $150 at a salon, this is a regular expense.

Skincare and Cosmetics: Don’t underestimate these costs, especially if you have specific skin concerns or preferences.

Clothing and Accessories: You need clothes, and they wear out. Budget for replacements and seasonal updates.

7. Debt Payments

Credit Card Payments

Here’s where I get real with my clients, if you’re only making minimum payments, you’re essentially renting your debt forever.

Minimum Payments: These need to be in your budget, but they shouldn’t be your goal.

Extra Principal Payments: Budget for paying more than the minimum if you want to actually eliminate debt.

Other Debt Obligations

Student Loans: Federal, private, parent PLUS loans, they all need their spot in your budget.

Personal Loans: Whether it’s a consolidation loan or that money you borrowed for home improvements.

Other Installment Debts: Furniture financing, medical payment plans, buy-now-pay-later arrangements.

8. Insurance Coverage

Essential Insurance Policies

Insurance feels like throwing money away until you need it. Trust me on this one, proper coverage saves you from financial disasters.

Life Insurance: Especially crucial if anyone depends on your income. Term life insurance is surprisingly affordable.

Disability Insurance: Your ability to earn income is your most valuable asset. Protect it.

Umbrella Policies: Extra liability coverage that kicks in when your other insurance limits are exceeded.

Specialized Coverage

Pet Insurance: If you have furry family members, this can save you thousands on unexpected vet bills.

Identity Theft Protection: In our digital world, this peace of mind is worth considering.

9. Phone and Communication Services

Mobile Phone Expenses

Your phone isn’t just a communication device anymore, it’s your lifeline to everything.

Monthly Phone Plan: Whether you’re on a family plan or flying solo, this is a fixed monthly cost.

Device Payments: If you’re financing that latest iPhone or Android, factor in the monthly payment.

Phone Insurance and Protection Plans: Screen repairs and replacements add up quickly without coverage.

Other Communication Costs

Landline Service: Yes, some people still have these, especially for home security systems.

International Calling Plans: If you regularly call family overseas, budget for these add-ons.

10. Entertainment and Subscriptions

Streaming and Digital Services

This is where budgets go to die in the modern world. All those $9.99 monthly charges add up to serious money.

Streaming Services: Netflix, Hulu, Disney+, HBO Max, Amazon Prime, audit your subscriptions quarterly.

Music Services: Spotify, Apple Music, YouTube Premium, do you really need multiple services?

Gaming Subscriptions: Xbox Game Pass, PlayStation Plus, mobile game subscriptions.

Software Subscriptions: Adobe Creative Suite, Microsoft Office, productivity apps.

Hobby-Related Expenses: Whether it’s crafting supplies, sports equipment, or book purchases.

Social Activities: Movie tickets, concerts, dinners with friends, budget for your social life.

11. Savings and Emergency Funds

Emergency Fund Contributions

If you’re not building an emergency fund, you’re setting yourself up for financial disaster. Start with $1,000, then work toward 3-6 months of expenses.

Monthly Emergency Fund Deposits: Treat this like a bill you can’t skip.

High-Yield Savings Account: Make sure your emergency fund is earning something while it sits there.

Short-Term Savings Goals

Vacation Fund: Spread the cost of that dream trip across several months instead of blowing your budget all at once.

Home Maintenance Fund: Homeowners need this for unexpected repairs and regular upkeep.

Gift Fund: Christmas and birthdays happen every year, they shouldn’t surprise your budget.

12. Retirement and Investment Contributions

IRA Contributions: Traditional or Roth, these need to fit in your monthly plan.

Employer Match: Make sure you’re getting the full company match – it’s free money.

Creating Your Complete Monthly Budget: Putting It All Together

Now that we’ve covered all 20 major expense categories, here’s how to put it all together without losing your mind.

Start by listing every expense category that applies to your situation. Don’t worry about getting the amounts perfect initially – you can adjust as you track your actual spending.

Use the 50/30/20 rule as a starting framework:

• 50% for needs (housing, utilities, groceries, minimum debt payments)
• 30% for wants (entertainment, dining out, hobbies)
• 20% for savings and extra debt payments

But remember, this is just a starting point. Your percentages might look different based on your income, location, and priorities.

Track everything for at least two months before making major adjustments. People are notoriously bad at estimating their own spending patterns.

Common Budgeting Mistakes to Avoid

After years of helping people with their finances, I’ve seen the same mistakes repeatedly. Here are the big ones:

Forgetting irregular expenses: Oil changes, birthday gifts, annual subscriptions – these aren’t surprises if you plan for them.

Underestimating variable costs: Groceries, gas, utilities – these fluctuate, so budget based on higher amounts, not best-case scenarios.

Not accounting for income taxes: If you’re self-employed or have irregular income, set aside money for taxes monthly.

Ignoring small subscriptions: Those $4.99 app subscriptions add up. Review your bank statements monthly for these sneaky charges.

Tools and Apps to Help You Succeed

IMO, the best budget is the one you’ll actually use. Here are some tools that make tracking easier:

Budgeting Apps: Mint, YNAB (You Need A Budget), PocketGuard, or even a simple spreadsheet.

Bank Tools: Most banks offer spending categories and budgeting tools within their apps.

Expense Tracking: Apps like Expensify for business expenses or Receipt Hog for cashback on purchases.

The key is consistency, not perfection. Pick one tool and stick with it for at least three months before switching.

Making Your Budget Work in Real Life

Here’s the thing nobody tells you about budgeting – it’s not about restricting yourself into misery. It’s about making intentional choices with your money so you can spend on what matters most to you.

Budget for fun: If you don’t include entertainment and personal spending, you’ll rebel against your budget within weeks.

Build in buffer room: Life happens. Budget 5-10% extra in variable categories like groceries and gas.

Review and adjust monthly: Your budget should evolve as your life changes. Don’t set it and forget it.

Celebrate wins: When you stick to your budget or reach a savings goal, acknowledge the achievement.

Final Thoughts: Your Money, Your Rules

Look, I could give you a perfect budget template, but it wouldn’t work for you because your life isn’t template-perfect. The best budget is one that reflects your actual spending patterns and priorities, not some ideal version of how you think you should spend money.

Start with these 20 comprehensive categories, cross off what doesn’t apply to you, and add anything I missed that’s specific to your situation. The goal isn’t to win a budgeting contest – it’s to gain control over your money so it works for your goals instead of mysteriously disappearing every month.

Remember, budgeting is a skill that improves with practice. Your first budget won’t be perfect, and that’s completely fine. The important thing is to start, track your progress, and adjust as you learn more about your spending habits.

FYI, if you find this overwhelming, start with just tracking your expenses for a month without trying to restrict anything. Understanding where your money goes is the first step toward making it go where you want it to go.

Your future self will thank you for taking control today. Trust me on this one, I’ve seen the transformation that happens when people finally get their budget right, and it’s pretty amazing to witness.
