Popular budgeting advice like the 50/30/20 rule — which allots a set percentage of income to necessities, wants and needs — is meaningless for people whose paychecks go up and down.
Freelancers, the self-employed, and those who depend on tips or commissions can have a great-paying month or a bad one, and that leaves them vulnerable. A Federal Reserve report released in May found that nearly a third of U.S. adults had irregular incomes in 2016 — and 40 percent of those struggled to pay bills as a result.
Financial experts' best advice is to plan ahead as much as possible, using creativity and new tech tools designed for those with irregular incomes. Here are four tips for managing money when your paycheck fluctuates.
1. Build an emergency fund
People with sporadic income should save nine months' worth of expenses in an emergency fund , says Todd Youngdahl, managing partner at Washington Wealth Advisors in Falls Church, Virginia.
That's more than the standard recommendation of three to six months' worth. The extra allows you to "dip in to cover expenses in a month that you don't get paid as much," Youngdahl says.
2. Budget what you spend
"When you have irregular income, you must live below your means," says Mark Kemp, a certified financial planner in Harleysville, Pennsylvania.
Add up the costs of your necessities, including housing, utilities, food, insurance and transportation, and include a monthly amount for annual bills, such as property taxes. An app that tracks spending, such as Mint or Personal Capital, can help you estimate.
Then find out if last year's earnings covered this baseline. If not, you might need to trim expenses.
3. Create a steady paycheck
Take control of your cash flow by setting up separate accounts for deposits and spending.
Deposit paychecks into one account. Each month, use it to pay yourself a "salary" that covers expenses. "This creates a steady monthly income that goes into the checking account your expenses are paid from," says Clayton Shearer, a certified financial planner at A&I Financial Services in the Denver area.
4. Use apps if you need an advance
If you don't have an emergency fund, a low-earning month could compel you to use high-interest credit cards or expensive payday loans. Instead, consider signing up for services such as these that offer cheaper alternatives for short-term cash:
• Activehours: Provides small, no-interest advances — up to $100 per day — against direct-deposit paychecks. Cost: An optional "tip" in the amount you choose.
• Dave: Offers no-interest advances until your next paycheck. Warns of upcoming bills or low bank balances to help avoid expensive overdrafts. Cost: $1 per month and optional tips.
• Even: Sets aside money from your paycheck if it's higher than average. When you earn less, Even makes deposits to bring you up to average until you get paid again, with no interest. Cost: Free if your employer offers Even as a benefit, or about $3 a week.
Financial experts caution against relying too often on cash advances. But these low-cost services can help you make it through a lean month — and then quickly get back to your monthly budget and savings plan.
