Callum Ostrander has worked as a budget advisor at a credit union in Ontario for eleven years. He agreed to walk through the mistakes he sees most often among clients who come in frustrated that their saving efforts are not working.
Treating savings as what is left over
The single most damaging habit Callum witnesses is saving whatever remains after spending. A client might intend to save $300 a month, but if it is not moved out of their account on payday, it rarely survives the month intact.
He calls this reactive saving. It feels like discipline, but the math rarely works in your favour because spending expands to absorb available balances.
Relying on averages instead of actual months
People average their utility bills across the year and budget that average figure. Then January arrives and the gas bill is double what they planned for.
Callum recommends budgeting to your highest expected month in each category, not the average. The surplus in lighter months becomes a genuine buffer rather than an accidental windfall.
Overlooking annual and irregular expenses
Car insurance renewals, dental cleanings, back-to-school costs — these are not surprises, but they regularly derail budgets because people do not account for them monthly. Callum sees clients go into debt every December simply because holiday spending was never built into their annual plan.
A straightforward fix: list every expense you know is coming in the next twelve months, total it, and divide by twelve. That monthly figure belongs in your budget as a separate category.
The question that changes everything
Callum ends most consultations by asking: do you know your actual monthly cost of living, down to the dollar? Most people are off by $400 to $800. That gap is usually where the saving opportunity hides.
