When you’re setting up your budget in Piere, one of the first questions you’ll need to answer is: should I use my gross or net income? It’s a surprisingly common source of confusion, but getting it right makes all the difference in creating a budget that actually works for you.

Understanding Gross and Net Income

Let’s start with the basics. Your pay stub shows you two important numbers, and they mean very different things:

Gross income is the total amount your employer pays you before anything comes out. If your job offers a $60,000 salary, that’s your gross income.

Net income (also called “take-home pay”) is what’s actually left after taxes and deductions are taken out. This is the money that lands in your bank account each payday.

Between gross and net, a lot gets withheld—think federal and state taxes, Social Security, Medicare, 401(k) contributions, and health insurance premiums. For many people, the difference is substantial. Someone earning $50,000 gross might only take home between $34,290 and $38,942 annually. That’s a gap of up to $15,710 a year, or roughly $1,300 a month. That’s real money you need to account for.

Which Number Should You Use for Budgeting?

Here’s the straightforward answer: use your net income for budgeting. Your net income represents the actual money you have available to spend and allocate toward your goals. If you build your budget around gross income, you’ll be planning to spend money that’s already promised elsewhere.

That said, some budgeting tools ask for gross income. If that’s the case, just make sure you add all your taxes and deductions as separate line-item expenses. The key is consistency and accuracy—not which number you choose.

Common Mistakes to Avoid

Double-Counting Expenses

This is the biggest pitfall, and it can throw your entire budget off track.

If you use net income, don’t list your payroll deductions (taxes, 401(k) contributions, health insurance, etc.) as expenses. They’re already accounted for in the lower number you’re working with.

If you use gross income, then yes—you’ll need to add all those deductions as separate expenses so you see the full picture.

The mistake? Using net income while also adding deductions as expenses. You’d be counting them twice, which makes your budget impossible to follow.

Here are common payroll deductions to watch out for:
– Federal and state income taxes
– Social Security and Medicare (FICA)
– Health insurance premiums
– 401(k) or retirement plan contributions
– Health Savings Accounts (HSAs)
– Wage garnishments

Forgetting About Annual Tax Events

Tax refunds and tax bills only hit once a year, which makes them easy to ignore when you’re thinking month-to-month. But they absolutely affect your cash flow and financial goals.

Here’s a practical fix: take your average annual refund or tax bill, divide it by 12, and add that monthly amount to your budget. That way, you’re not blindsided by a large payment in April (or pleasantly surprised by a refund). You’re spreading it out evenly and staying prepared.

If you typically get a large refund, consider treating it as bonus money for your financial goals rather than part of your regular spending budget.

Why This Matters for Your Money

Getting the gross vs. net question right isn’t just about picking a number—it’s about understanding how much money you actually have to work with. When Piere helps automate your savings and debt payoff, we need that accurate picture of your real, available funds. The difference between gross and net can literally be thousands of dollars a year, and that changes everything about what’s possible for your goals.

So before you start building your budget or connecting Piere to your accounts, take a moment to pull up your pay stub and get clear on your actual net income. That’s the number that should drive your financial decisions and help your money move you forward.
