What is a fluctuating income?

If you earn roughly the same amount of money each month, either through a salary or by working a similar number of hours, then your monthly income is fairly predictable. Many people do not have that consistency because they have a fluctuating income. If it’s hard for you to predict how much you’ll earn or how many hours you may work each month, then you have a fluctuating income. This is also sometimes called income volatilityVolatility The rate at which the price of a security increases or decreases for a given…+ read full definition.

Many Canadians have a fluctuating income. It’s common for people who do seasonal work, are self-employed, or who work in the gig economy. Others may have a combination of predictable and fluctuating incomes. This might involve working a steady job each month but supplementing that income with freelance work to make ends meet or to save. Or for others, part of their income may come from commissionsCommissions What you pay to a broker or agent for their services.

If you have a fluctuating income, following a monthly budget can feel intimidating, but it can be a good step to take to help you reach your financial goals.

How do you budget on a fluctuating income?

A typical monthly budget compares your recurring income with your recurring expenses. If your income changes each month, you might find a different approach helpful. Consider trying these steps:

  1. Estimate how much you need to cover your essential monthly expenses – Your necessary monthly expenses are probably easier to predict. Calculate the minimum amount you need each month to cover essential expenses. This includes rent or mortgageMortgage A loan that you get to pay for a home or other property.

  2. Estimate your average monthly income – If you can’t predict the future, you can look to the past to estimate your average monthly income.

You direct all your income to one account. Then make monthly transfers to the account you use to pay for expenses.

The benefit of this system is that it keeps you focussed on covering your necessary expenses. And it keeps your surplus income in a separate account. If you earn more money than you need that month, it can stay in the account as income for the next month, or you can put some of it towards savings. 

It’s a good idea to regularly review your budget, particularly as your situation changes. If you find your expenses increase or you’re earning more predictable income, you can change how much you put towards each part of your budget.

An alternative to using your average income as a monthly estimate, is to use your lowest likely monthly income. If this amount is enough to cover your minimum expenses, then during other months you can count on having more room for discretionary spending or saving for the future. 

What else can you do to manage your money on a fluctuating income?

While budgeting is important, there are other ways to help you manage your money. You could:

  • Build your emergency fund – Once you’re able to consistently cover your monthly expenses, consider putting aside extra money towards an emergency fund. Ideally your emergency fund would cover at least three months of expenses. But it can even help to have enough saved to cover a surprise expense or one month’s rent. 
  • Plan for peaks and valleys – You might be able to predict certain times of the year when your expenses are higher (holiday gift-giving, back-to-school, recurring professional expenses). If you can, set aside a little extra money for these times in advance. Similarly, you can plan for times when you’ll bring in more income (taxTax A fee the government charges on income, property, and sales.

Summary

Budgeting on a fluctuating income can be difficult. Consider these tips to help you budget when your income is unpredictable:

  • Cover your essential monthly expenses first and use that to build your budget.
  • Estimate your monthly income by averaging your total income over several months or years. Or budget using your lowest monthly income.
  • Direct all your income to one account and set up monthly transfers to an account to pay for expenses.
  • Build an emergency fund.
  • Plan ahead for times when you’re likely to have a higher income or expenses and budget accordingly.
  • Set priorities for your savings and investment goals.
