Callum Breckenridge has spent 14 years reviewing small business finances in Vancouver. We asked him what beginners consistently get wrong when they first try to forecast their money.
The most common starting mistake
Most people try to forecast too far ahead. A 12-month projection sounds responsible, but for someone new to tracking their own finances, it usually ends up being fiction dressed as planning. Callum starts clients with a rolling 8-week window instead.
What works in favour of basic forecasting
- Even a rough estimate forces you to look at income timing, not just totals
- Identifying gaps between when bills are due and when income arrives can prevent overdrafts
- A simple spreadsheet in Google Sheets works fine, no paid software needed
What makes forecasting harder than expected
- Irregular expenses like car repairs or dental costs are easy to forget until they appear
- People tend to overestimate income and underestimate spending, consistently
- Emotional attachment to best-case scenarios skews projections toward optimism
Callum shared a practical habit that stuck with us. He reviews his own forecast every Sunday for 10 minutes, adjusting the next two weeks based on what actually happened. That feedback loop, he argues, is what separates useful forecasting from wishful numbers on a page.
Starting with realistic numbers rather than aspirational ones makes the whole process more grounding than stressful.
