Key points
  • Lenders often discount variable income components or require a longer history before counting them in full.
  • Treatment varies significantly between lenders — ask directly rather than assume.
  • Your own safe budget should use a conservative income estimate, separate from what a lender allows.

How lenders commonly treat irregular income

Casual, seasonal or commission-based income is often assessed more conservatively than a stable salary — some lenders apply a discount to variable income components (for example, only counting a percentage of overtime or commission), or want a longer history showing consistency before relying on it. Exact treatment varies significantly between lenders, so getting a clear answer early is worth the time.

Budgeting around your own variability

Separately from what a lender will count, your own safe budget (see the safe-budget guide) should be based on a conservative, lower-than-average income estimate — not your best month — so a genuinely quiet period doesn't immediately threaten your repayments.

Common mistake: assuming a lender will count 100% of irregular income components at face value. Ask specifically, rather than assuming your full quoted income will be used in the assessment.

Practical checklist

Before applying with variable income

  • Gather at least 6-12 months of payslips or income statements showing the pattern
  • Ask each lender how they treat overtime, commission or casual hours specifically
  • Base your own safe budget on a conservative, lower-than-average income figure

Questions for a professional

  • What percentage of my variable income will you count toward serviceability?
  • How many months or years of history do you need to see?
