Questions About Variable Income Budgeting?

The key is building a budget around your baseline income—the lowest amount you typically earn in a slow month—rather than averaging your best months. Once you know that floor, you can plan essential expenses there and treat anything above it as bonus funds for taxes, savings, or seasonal spending. This approach means you're never caught off-guard when work dries up.

Most financial advice says 3–6 months of expenses, but for contractors we recommend aiming higher—closer to 6–9 months if possible. Since you don't have the safety net of a steady paycheck, having that cushion means you can turn down low-paying work or weather a client loss without panic. Even building it slowly, month by month, makes a huge difference.

Set aside a percentage of every invoice—typically 25–35% depending on your province and tax bracket—into a separate account the moment you're paid. Don't touch it. Quarterly tax installments are due March 15, June 15, September 15, and December 15, so knowing roughly what you've set aside keeps you from scrambling. Your accountant can help you dial in the exact percentage for your situation.

Yes, it's one of the smartest moves you can make. Have one account for business income, one for taxes, one for operating expenses, and one for personal spending. This sounds complicated but it actually makes budgeting easier —you can see at a glance what's available to spend versus what's earmarked for April's tax bill. It also simplifies bookkeeping and CRA audits.

If you know December's always quiet or summer dips, you can plan for it. During your busy months, set aside extra funds specifically for those lean periods. Track your patterns over a year or two to see exactly when the dips hit and how deep they go. Once you've mapped it out, you can adjust your variable expenses—like marketing or training—to peak during high-earning months and dial back when money tightens.

Monthly is ideal—spend 20–30 minutes looking at what came in, what went out, and whether your baseline estimate is still accurate. Every few months, also review your savings targets and tax set-aside percentage. If you've picked up new types of work or lost a major client, your budget needs to shift too. It's not set-and-forget; it's a living tool that evolves with your business.
