Understanding Disposable Income and What to Do With It
Money comes in. Taxes come out. What’s left is called disposable income. It’s the money you take home after taxes.
Between 1990 and 2023, Indiana's per capita disposable income rose from $15,633 to $54,717[1]. This represents an increase of about 250% over 33 years. However, Indiana’s economy is expected to grow more slowly in the next year[2]. This could make it harder for incomes to keep rising.
So, how do you manage the money you have available after taxes are paid? Here, you’ll learn what disposable income is, how to find yours, and smart ways to use it. You’ll find out how much you can safely spend, how much to save, and how to plan for the future.
What Is Disposable Income?
Disposable income is the money you have left after paying your taxes. You can use this money to pay for needs, like rent or food, or for wants, like new clothes or a weekend trip. It’s also what you can use to build your savings or pay down debt.
What Is Not Included in Disposable Income?
Taxes are the only thing taken out before you calculate disposable income. This includes:
Federal income taxes
State income taxes (if your state charges them)
Social Security and Medicare taxes
Things like rent, groceries, and gas are not subtracted yet. That comes next when you figure out what’s left for fun or savings.
How to Calculate Disposable Income
Here’s a simple formula: Your income – taxes = disposable income
Let’s look at an example: You earn $3,000 each month. You pay $500 in taxes.
$3,000 – $500 = $2,500, which means you would have $2,500 in disposable income.
If you're paid hourly or your paycheck changes, this number might change each month. In that case, track your income and taxes for a few months, then find your average.
Disposable Income vs. Discretionary Income
These two terms are often confused. Here’s the difference:
Disposable income is what’s left after taxes.
Discretionary income is what’s left after taxes and covering your basic needs.
Let’s say you make $2,500 after taxes. You might spend $2,000 on rent, bills, loan payments, and food. That would leave $500 of discretionary income — the money you have for fun or extra savings.
Knowing the difference helps you plan better. Disposable income shows what you could spend. Meanwhile, discretionary income shows what you really have left for non-essentials.
What to Do With Your Disposable Income
Once you know how much disposable income you have, the next step is deciding what to do with it. This is where smart money habits come in.
1. Cover the Essentials First
Even though you’ve already paid taxes, you still need to pay for things like:
Rent or mortgage
Groceries and personal care
Utilities (gas, electric, water)
Car payments or public transport
Health insurance and medications
These are your needs, and they come first.
2. Start Saving (Even a Little)
After covering needs, save as much as you can — even if it’s just a few dollars. Disposable income makes saving possible, and every bit helps.
You can start with small goals and build up. A little can go a long way over time.
Good savings goals might include:
A $500 emergency fund
Saving for school or a new car
A vacation or holiday fund
Long-term savings for a home or retirement

3. Pay Down Debt
If you have credit cards, student loans, or other debt, it’s smart to use part of your disposable income to pay it down faster. The sooner you pay off debt, the less you spend on interest.
You can start with the smallest balance (snowball method) or the highest interest rate (avalanche method). Choose whichever strategy helps you stay motivated. Use a debt consolidation calculator to find out how much combining your debt might help you save.

4. Use Some for Fun
Once you’ve handled needs, savings, and debt, it’s okay to spend a little on things you enjoy. This helps you stay balanced and enjoy life while staying on track.
Some fun-but-smart ways to spend might include:
Going out to dinner once a month
Buying something for your home
Treating your family to a local event
Donating to a cause you care about
Just make sure you're not spending more than you have. Keep fun spending within limits so you don’t lose progress.

Your disposable income may go up or down based on life events. A new job, a raise, a move, or even tax changes can all shift your numbers. It’s a good idea to check your budget and savings plan every few months and make updates if needed.
