Personal Finance Foundations: Lesson 2 – Budgeting 101

Learn how to create and maintain a personal budget that works for your lifestyle and helps you achieve your financial goals.

Start Budgeting!

Introduction to Budgeting

Picture this: You've got $150 to get through the next two weeks. You need groceries, gas, and maybe a little fun with friends. How do you make it stretch without stressing? That's budgeting—a plan you make before you spend to ensure your money does what you want.

What's a Budget, Really?

A budget is your game plan for your money. It's deciding upfront how much goes to essentials (like rent or food), how much you'll save, and how much you can spend on stuff you enjoy. Think of it like plotting a road trip: you know your destination (your goals), your fuel (your income), and the stops along the way (your expenses). Without a map, you might run out of gas—or cash—halfway through.

Why Bother Budgeting?

Here's the detailed scoop on why it's worth your time:

Stats to Prove It:

A 2021 survey by the National Foundation for Credit Counseling found that 60% of people who budget feel more in control of their finances.

Meanwhile, 34% of Americans don't have a budget—and they're twice as likely to stress about money. Coincidence? Nope!

Real-Life Example:

Meet Sarah, a 25-year-old barista earning $1,200 a month. Without a budget, she'd blow $400 on takeout, $300 on clothes, and $500 on rent—then scramble when her $100 electric bill hit. After budgeting, she set $600 for rent and bills, $300 for food, $200 for fun, and $100 for savings. Now, she's got cash left over and no bill panic. That's budgeting in action!

Historical Fun Fact:

Budgeting isn't new—ancient Romans used "tabulae" (tablets) to track income from taxes and expenses for aqueducts. Even back then, they knew planning beats winging it!

Your Turn to Reflect:

Why do you want to budget? Is it to stop living paycheck to paycheck? Save for something big? Write down one personal reason—it'll keep you motivated.

Example: "I want to save $300 for a concert without stressing."

Got it? Awesome! Let's lay the groundwork with your income.

Understanding Your Income

You can't budget without knowing your starting pile of cash. Income is every dollar that flows into your hands, from any source, over a set time (usually a month). Let's break it down.

Types of Income:

How to Calculate It:

  1. List every source: Write down every way you get money in a typical month.
  2. Estimate totals: For regular income, use exact amounts. For irregular, guess low (better safe than sorry).
  3. Add it up: That's your monthly income—the fuel for your budget.

Example Breakdown:

If It Varies:

Freelancers or gig workers might earn $200 one month, $400 the next. Use an average (add three months, divide by 3) or the lowest amount you expect—like $200—to stay safe.

Activity: Map Your Income

List your income sources—every penny counts! Then calculate your total.

Example: "$150 from lawn mowing, $25 allowance, $10 from selling candy" = $185

Conversion Tips:

Detailed Example:

Let's say you babysit. Last month, you made $50 one night, $30 another, and $20 selling cookies. That's $100—but it's not steady. Budget with your reliable $50 allowance instead, and treat the rest as a bonus.

Got your number? Sweet! That's your budget's foundation. Next, we'll see where it's all going.

Identifying Your Expenses

Expenses are everything you spend money on. To budget, you need to know what's leaving your wallet—and why. They split into two big buckets: fixed and variable.

Fixed Expenses:

These don't budge month to month—they're your "gotta pay" costs.

Variable Expenses:

These shift based on your choices or needs—they're your "can tweak" costs.

Hidden Expenses:

Don't skip the sneaky stuff—like $2 vending machine sodas or $5 in-app purchases. They're small but stack up fast.

Detailed Example:

Take groceries. You might budget $50, but one week you grab extra snacks ($10), then splurge on fancy cheese ($15). Suddenly, it's $75. Tracking these swings helps you plan better.

Activity: Sort Your Expenses

Sort these into fixed or variable:

Fixed Variable Apartment rent
Fixed Variable Movie tickets
Fixed Variable Wi-Fi bill
Fixed Variable Groceries
Fixed Variable Gym membership
Fixed Variable Coffee shop runs

Answers: Fixed—Apartment rent, Wi-Fi bill, Gym membership; Variable—Movie tickets, Groceries, Coffee shop runs

Your Turn:

List your expenses—three fixed, three variable. Be specific!

Example: Fixed—$50 phone, $20 Spotify, $30 transit; Variable—$40 food, $15 games, $20 gifts

Pro Tip: The Coffee Trap

Spend $3 on coffee five times a week? That's $15/week, $60/month, $720/year. Could that fund a new laptop? Budgeting lets you decide—coffee or laptop?

Creating Your Simple Budget

Time to make your money work! A budget matches your income to your expenses. Here's the step-by-step:

  1. Start with Income: Your total from Section 2.
  2. List Fixed Expenses: Add them up.
  3. List Variable Expenses: Add them up.
  4. Total Expenses: Fixed + Variable.
  5. Subtract: Income minus Total Expenses.
  6. Surplus: Extra cash left (yay!).
  7. Deficit: Spending too much (time to adjust).

Example Budget:

What's That $70 For?

Fixed Expenses:



Total Fixed: $0.00

Variable Expenses:



Total Variable: $0.00

Total Expenses: $0.00

Surplus/Deficit: $0.00

Reflection:

What's your result? Surplus? Deficit? Write one thought.

Example: "I've got $20 left—cool, I can save it!"

Handling a Deficit:

If expenses beat income (e.g., $500 income, $550 expenses = $50 deficit):

Detailed Scenario:

You've got $300 income, but $150 rent, $40 phone, $80 groceries, $50 fun = $320. Deficit of $20. Options:

Your budget's alive now! Next, we'll keep it on track.

Tracking Your Budget

A budget's only as good as your follow-through. Tracking means watching your spending to match your plan—like checking your phone's GPS to stay on route.

Why Track?

Tracking Methods:

Apps:

Spreadsheets:

Envelope System:

Activity: Pick and Explore

Choose one method. Try it (download an app, set up a sheet, or grab envelopes). Write one pro and one con.

Example: "Spreadsheets—Pro: I control it; Con: Takes 10 minutes daily."

Detailed Example:

Budget $40 for fun. Spend $15 on a movie (log it), $10 on snacks (log it). Check your app/spreadsheet—$15 left. No guessing, no overspending.

Challenge:

Track one category (e.g., "food") for a week. Log every expense. Did you stay under? Over? Write what you learned.

Example: "I budgeted $50 for food, spent $60—too many sodas!"

Tracking's your budget's heartbeat—keep it pumping!

Adjusting Your Budget

Life's not static, and neither is your budget. Jobs change, bills pop up, goals shift. Adjusting keeps you in control.

When to Adjust:

How to Adjust:

Scenario 1: Unexpected Expense

Your phone screen cracks—$150 to fix, unbudgeted.

Scenario 2: Income Drop

Your hours get cut—income falls from $400 to $300.

Scenario 3: Income Boost

You get a $100 raise—now $500/month.

Activity:

Think of a real or possible budget hiccup. How would you adjust? Detail your plan.

Example: "Car tire flat—$80. I'd cut $40 groceries (buy basics), $40 fun (no movies)."

Pro Tip: The Buffer

Add a $20-30 "miscellaneous" category monthly. It's your safety net for surprises—like a $15 gift or $25 repair.

Detailed Adjustment Example:

Budget: $400 income, $250 fixed, $120 variable = $370 (surplus $30). Then, a $50 vet bill hits. Adjust:

Adjusting's not failing—it's winning at flexibility.

Common Budgeting Mistakes (and Fixes)

Even pros slip up. Here's how to avoid the biggies:

Mistake: Skipping Small Stuff

Mistake: Too Rigid

Mistake: Set-and-Forget

Mistake: Guessing Expenses

Activity:

Which mistake sounds like you? Write it and one fix.

Example: "I guess too much—I'll check my bank for grocery costs."

Detailed Example:

You skip tracking $5 daily smoothies. That's $25/week, $100/month—half your fun budget gone! Fix: Log it daily, cut to $10/week, save $60/month.
