Worked Example

Let's calculate the cost of living for someone in San Francisco with these monthly expenses:

Category	Your Expense	National Average
Housing	$3,500	$1,200
Transportation	$300	$250
Food	$600	$400
Healthcare	$400	$300
Utilities	$200	$150
Other	$300	$200

Using the formula:

COLI = (35% × (3500/1200)) + (15% × (300/250)) + (15% × (600/400)) + (15% × (400/300)) + (10% × (200/150)) + (10% × (300/200))

= 35% × 2.916 + 15% × 1.2 + 15% × 1.5 + 15% × 1.333 + 10% × 1.333 + 10% × 1.5

= 1.0206 + 0.18 + 0.225 + 0.2 + 0.1333 + 0.15

= 2.0189

This person's cost of living index is 201.89, meaning their expenses are 101.89% higher than the national average.
