Budgeting Benchmarks: How Much Should You Be Spending?

Intro

Some of the most common questions I hear are:

\"How much should I be spending on my rent or mortgage?\"
\"How much should I be spending on my car payment?\"
\"Do I spend too much going out to eat?\"

Most people have a rough idea of what they can afford with these things, but few know how much they should be spending in these areas.

Without outlined goals and clear benchmarks, it's easy to slowly overspend without realizing the long-term impact. Lifestyle creep often happens gradually through these exact spending categories.

This post lays out general budgeting benchmarks and targets to help you evaluate your current spending. The goal of budgeting isn't restriction, it's about intentionally allocating your dollars to what matters most to you.

We'll break everything into:

Fixed Costs
Variable Costs
Other Priorities (Savings & Debt)

Fixed Costs

Fixed costs are expenses that don't change much month to month. Since these expenses are harder to adjust quickly, it is critical to get them right the first time, otherwise you risk boxing yourself into an inflated lifestyle that limits future flexibility.

Housing: Rent or Mortgage

Housing is typically your largest expense, which means it has the biggest impact on your financial flexibility.

Two commonly used housing benchmarks:

Housing Ratio #1: Housing costs ÷ Gross income ≤ 28%

Housing costs include:

Rent or mortgage payment
Property taxes
Homeowners insurance
HOA fees

This is the standard benchmark lenders use when evaluating borrowers for conventional mortgages.

Housing Ratio #2: (Housing costs + other debt payments) ÷ Gross income ≤ 36%

This second ratio looks at the full picture, not just housing, but also student loans, car payments, and credit cards.

Home Maintenance Rule of Thumb

If you own a home, budgeting doesn't stop at the mortgage.

Set aside ~1% of the home's value each year for maintenance.

For example:

$400,000 home → ~$4,000 per year (~$350/month)

This helps cover repairs, replacements, and inevitable surprises without derailing your monthly budget.

I recommend that you open separate savings \"buckets\" within your high-yield savings account to set aside funds for these expenses.

Car Payment

Cars are one of the easiest ways to derail an otherwise solid financial plan.

A simple framework to keep things in check:

The 20/4/10 Rule

20% down payment
4-year loan maximum
Total car costs ≤ 10% of net monthly income

The 20/4/10 rule prevents long loans, keeps payments manageable, and reduces the chance that you're driving a car that competes with your savings goals.

Variable Costs

Variable costs change month to month. These categories provide more flexibility, but they require intentional limits.

Groceries & Dining Out

For evaluation purposes, it's helpful to look at groceries and dining out together (even though they should be separate line items on your actual budget).

Target food benchmark: 10-15% of gross income

For groceries, tools like grocery pickup or online ordering (ClickList, Instacart, etc.) can be incredibly helpful because you can see your total before checkout, adjust to hit your budget, and avoid impulse purchases.

For dining out, the \"why\" matters more than the \"what.\" Ask yourself:

How much of my eating-out spending is alone vs. with others?
How much time am I really saving by going out?
Could I cook a healthier or cheaper version at home?

For lunches, meal prepping is one of the most effective ways to control costs and improve nutrition.

Date Nights & Entertainment

Rather than setting a vague \"fun money\" number, try this approach:

Decide what a typical date night or outing should cost
Decide how many per month
Multiply → that's your budget

Example: $75 per date night × 4 per month = $300

Also, remember some of the best experiences cost $0.

Medical Expenses & Auto Service

Two of the most unpredictable expense categories are your health and your vehicle. You may not have medical bills or car repairs every month, but those costs are inevitable, and failing to plan for them is a common mistake I see people make with their personal finances.

When it comes to healthcare, your situation is highly personal. If you visit the doctor frequently, take ongoing medications, or have an underlying condition, you may need to set aside more than average for medical expenses.

If you're eligible for a Health Savings Account (HSA), it can be an excellent tool for this purpose, offering both tax advantages and flexibility. If you're not eligible, setting aside funds in a high-yield savings account can still help ensure medical expenses don't turn into financial stress.

The key is consistency, setting aside money regularly, even during months when healthcare costs are low.

The same principle applies to the \"health\" of your vehicle. Routine maintenance (oil changes, tire rotations, filter replacements, etc.) can be planned for, while larger, less frequent expenses like new tires or brake repairs are harder to predict.

Regardless, these costs are not optional. Baking a monthly auto maintenance amount into your budget helps prevent surprise expenses from turning into credit card debt or forcing you to pull from other financial goals.

By treating medical and auto expenses as predictable over time, even if they're irregular month to month, you build buffer into your budget and reduce unnecessary stress when those expenses inevitably come up.

Other Priorities: Savings & Debt

These categories don't always feel urgent, but they're the foundation of long-term financial freedom.

Retirement Savings

If you start early, you don't need extreme savings rates to build real wealth. Assuming you are starting in your 20s or early 30s, you should be aiming to allocate 10-13% of your gross income towards retirement savings. For a deeper look at how much you should have saved by 30 and 40, the benchmarks give you a useful gut check.

Employer Match

If your employer offers a match, contributing enough to receive the full match should be your minimum. Otherwise, you're leaving free money on the table.

Debt Reduction

Not only is high interest debt mentally draining, it limits every other financial goal. While specifics of debt reduction strategies are beyond the scope of this post, your priorities should include: eliminating credit card balances, creating a plan for student loans, and avoiding financing unnecessary expenses with debt. The pay-off-debt-or-invest framework helps you decide which to tackle first based on your interest rates.

Rule of thumb: If debt payments are crowding out savings or causing stress, it's time to prioritize payoff before lifestyle upgrades.

Final Thoughts

If your numbers don't line up perfectly, that doesn't mean you're necessarily doing anything wrong. It simply means there are opportunities to make intentional adjustments that align with the long-term goals you have for you and your family.

This post isn't exhaustive, it's meant to provide general benchmarks for major monthly expenses.

Use it as a starting point to reflect on your spending and make adjustments that move you closer to the financial life you actually want.
