A **budget** is a plan for how you will use your money. It is not about restricting
yourself; it is about telling your money where to go instead of wondering where 
it went. People who budget are better prepared for surprises and more likely to 
reach their goals. In this lesson you will learn how to build a realistic budget
and why an emergency fund matters.

## Step 1: know your income

Start with your **net income**, the money you actually receive after deductions.
If your income varies, for example from tips or irregular shifts, use a careful 
estimate based on a lower-than-average month.

### Step 2: track your spending

Before planning, track what you actually spend for a few weeks. Many people are 
surprised by small, frequent purchases such as snacks, delivery fees and in-app 
purchases.

### Fixed and variable expenses

 * **Fixed expenses** stay about the same each month: rent, phone contract, subscriptions,
   loan repayments.
 * **Variable expenses** change: groceries, transport, entertainment, clothing.

### Needs and wants

 * **Needs** are essentials for living and working: housing, basic food, utilities,
   transport to work or school, essential healthcare.
 * **Wants** improve life but are not essential: eating out, streaming services,
   the latest phone, concert tickets.

Some items are partly a need and partly a want. Food is a need; a daily takeaway
coffee is a want.

## Step 3: make a plan

### The 50/30/20 guideline

One popular starting point divides net income into three parts:

  |  Category |  Share |  Includes |  
   |  Needs |  50% |  housing, groceries, transport, utilities |  
 |  Wants |  30% |  entertainment, eating out, hobbies |  
 |  Savings and debt |  20% |  emergency fund, goals, extra debt payments |

This is a **guideline, not a rule**. In expensive cities, needs may take more than
50 percent. A student living at home might save much more than 20 percent.

### Worked example

Sofia takes home **2,000 dollars** per month.

 * Needs (50%): 2,000 × 0.50 = **1,000 dollars**
 * Wants (30%): 2,000 × 0.30 = **600 dollars**
 * Savings and debt (20%): 2,000 × 0.20 = **400 dollars**

Total: 1,000 + 600 + 400 = 2,000 dollars. Every dollar has a job.

### Pay yourself first

A powerful habit is to **pay yourself first**: move your savings into a separate
account as soon as you are paid, before spending on wants. Automatic transfers make
this effortless.

## Step 4: review and adjust

A budget is a living plan. Review it monthly. If you overspend in one category, 
adjust another. Use whatever tool suits you: a notebook, a spreadsheet or a budgeting
app.

### Example

Leo budgeted 100 dollars a month for eating out, but tracking showed he spent 180.
Instead of giving up, he set a weekly limit of 30 dollars, started bringing lunch
twice a week and found a cheaper phone plan to free up money. Next month, he stayed
within budget and added the savings to his travel fund.

## Emergency funds

An **emergency fund** is money set aside for unexpected costs, such as a broken 
phone, a medical bill or a car repair, or for a temporary loss of income. Without
one, people often turn to expensive borrowing.

### How much?

Many financial educators suggest that working adults aim for an emergency fund covering
about **three to six months of essential expenses**. For a teenager, a first goal
might be a smaller amount, such as a few hundred dollars. Build it gradually, and
keep it in a separate, easily accessible savings account so you are not tempted 
to spend it.

### Sinking funds

Some costs are predictable but irregular, such as birthday gifts, holidays or annual
subscriptions. A **sinking fund** means saving a little each month for these. For
a 240-dollar yearly expense, saving 20 dollars a month means the money is ready 
when needed.

### Budgeting with irregular income

If your income changes from month to month, base your budget on a **low** month,
not an average one. In good months, put the extra into savings or your emergency
fund. That buffer then covers essentials during quieter months, so a slow week does
not become a crisis. Some people pay themselves a fixed “salary” from a holding 
account each month to smooth out the ups and downs.

## Key takeaways

 * Budget using net income and track spending to see where money goes.
 * Separate fixed and variable expenses, and needs and wants.
 * The 50/30/20 guideline is a flexible starting point; pay yourself first.
 * Build an emergency fund and use sinking funds for predictable irregular costs.

## Practice

Ravi takes home **1,500 dollars** a month. **1.** Using 50/30/20, how much goes 
to needs, wants and savings? **2.** He wants to save for a 600-dollar laptop in 
6 months. How much must he save monthly, and does it fit in his savings category?

Answers: 1 needs 750, wants 450, savings 300 dollars. 2 600 ÷ 6 = 100 dollars per
month, which fits within his 300-dollar savings amount.
