Episode notes

Do you ever feel like budgeting is impossible because your income changes from month to month? If you’re self-employed, work on commission, or depend on tips, you’re not alone. Living on a variable income can feel like riding a financial roller coaster—one month you’re doing fine, and the next, you’re wondering how to make ends meet.

But the good news is that God’s Word offers wisdom that applies even in seasons of financial uncertainty. Proverbs 21:5 reminds us:

“The plans of the diligent lead surely to abundance, but everyone who is hasty comes only to poverty.”

No matter how steady—or unpredictable—your income is, a plan is essential.

Build Your Budget on What You Know, Not What You Hope

Many people make the mistake of budgeting around their best month. Wise stewardship means basing your plan on your lowest or average month, rather than your highest month.

Start by reviewing your income over the past 6 to 12 months. Identify your lowest earning month, and use that as your “bare minimum” budget—what it takes to cover essentials like housing, utilities, groceries, transportation, and basic giving.

For example, if your income ranges from $3,000 to $6,000, plan your budget around $3,000. When you earn more, that extra income becomes your margin—money you can use to pay down debt, save, or plan ahead for slower seasons.

This approach protects you from overcommitting when income drops and helps you live within your means.

Create an Income-Holding Account

When your income arrives irregularly, timing can be just as stressful as the amount. One simple solution is to use an income-holding account.

Here’s how it works:

Deposit all income into one central account—your “holding tank.”
Once a month, transfer your budgeted amount into your regular spending account.

This method smooths out your cash flow, allowing you to “pay yourself” a steady income each month. Proverbs 27:23 gives this timeless reminder:

“Know well the condition of your flocks, and give attention to your herds.”

In today’s world, that means knowing where your money is, where it’s going, and when it’s available.

Also, if your income fluctuates, an emergency fund isn’t optional—it’s essential.

Start by saving enough to cover one month’s expenses, then aim for three to six months over time. Use “boom” months to grow your buffer before adding new spending. When slower seasons come, you’ll be able to keep paying yourself consistently.

Differentiate Between Fixed and Flexible Expenses

Another key to managing a variable income is learning to distinguish between fixed and flexible expenses.

Fixed expenses—like rent, insurance, and loan payments—stay the same.
Flexible expenses—like dining out, entertainment, or travel—can adjust with your income.

During lean months, trim flexible spending. When income increases, you can replenish your savings or increase your giving. Remember, self-control is one of the fruits of the Spirit (Galatians 5:22–23), and that includes how we handle our finances.

One of the easiest ways to get off track is through “surprise” expenses that shouldn’t be surprises—car repairs, insurance premiums, or property taxes.

List all your irregular expenses for the year and divide each by twelve. Set that amount aside monthly in a sinking fund, so when those bills come, you’re ready. No scrambling. No stress. Just peace that comes from faithful planning.

Trust the Provider, Not the Paycheck

Even when your income is unpredictable, God is not. Matthew 6 reminds us that our Heavenly Father knows what we need before we ask. He feeds the birds and clothes the flowers—and He will provide for His children.

So whether your income changes weekly or seasonally, rest in this truth: stability isn’t found in your paycheck—it’s found in God’s faithful provision.

On Today’s Program, Rob Answers Listener Questions:

I’ve been able to save about $170,000 and add around $10,000 each month. Once I reach $200,000, I’d like to start investing $10,000 a month in something with greater growth potential, even if it carries a bit more risk. Right now, I’m earning about 4% at the bank. What would be a wise next step for that money?
I’ve just moved into an independent living facility and am in the process of selling my condo, which should close soon. I’ll need the proceeds to help cover my living expenses, but I’m wondering—how should I handle tithing on that money?
I just wanted to express my gratitude for the way you and your team share wisdom so respectfully and thoughtfully. Listening to your program has really deepened my understanding and helped me grow.
