The Patterson family in Austin built their forecast on two stable incomes: $95,000 and $78,000. Three kids, ages 5, 7, and 9. Their projection showed comfortable college funding by 2030.

Then the tech layoffs hit. Not permanently, but the six-month gap revealed how fragile their forecast was.

During that period, they burned through:

• $8,400 from emergency fund
• $5,200 from college savings
• $3,100 from retirement accounts with penalties

Their forecast had never modeled income interruption. They assumed continuous employment with 3% annual raises.

The families who build resilient forecasts run stress tests. What if one parent takes a sabbatical? What if someone pursues lower-paying but more fulfilling work? What if health issues force reduced hours?

For the Pattersons, rebuilding meant creating scenario models: base case with both incomes, conservative case with one income, crisis case with neither. Each scenario has different savings rates and different education options.

Now they maintain six months of expenses in cash, keep college savings in flexible vehicles, and review assumptions quarterly. The forecast isn't about predicting the future. It's about preparing for multiple versions of it.
