Breaking Down the Cost
Here is what the Iran war is adding to a typical US household’s monthly expenses as of mid-March 2026:
Gas: +$40-60/month
Gas prices are up 17% nationally since Feb. 28. If your household uses 60-80 gallons per month (typical for two-car families), that is an extra $40-60 at the pump. California families are paying even more with prices above $5/gallon.
Groceries: +$50-80/month
Economists estimate food-at-home inflation could rise by 2 percentage points. For a family spending $800-1,000/month on groceries, that translates to $50-80 more. This will get worse as fertilizer shortages hit spring planting.
Energy Bills: +$20-40/month
Heating oil, natural gas, and electricity costs are all climbing. Heating oil hit $5/gallon in some Northeast markets. Even homes with solar are affected by grid electricity rate increases.
Transportation/Shipping: +$10-30/month
Everything you order online costs more to ship. Uber and Lyft prices are up. Delivery fees have increased.
Travel: +$100-500 per trip
If you are planning travel, airfares are up 15-35%. Hotels in many markets are also rising.
Total Household Impact: $150-250/month
That is $1,800-3,000 per year if the conflict continues at current intensity. Lower-income households feel this most acutely since energy and food make up a larger share of their budgets.
