Monthly estimate
Estimate what your daily commute costs per month. Enter round-trip distance, fuel or electricity assumptions, and commute days to compare gas and EV commuting.
If your round-trip commute costs $5 and you commute 20 days per month, the monthly estimate is $100. Small daily differences can become meaningful over a full year.
A commute looks small when you only think about one drive. The monthly and yearly totals are where the number becomes useful. A $4 difference per commute day is about $80 over 20 workdays, or roughly $960 over 12 similar months.
That is why this calculator is useful for comparing a new job location, deciding between gas and EV driving, or estimating the real cost of returning to office days.
A fixed 20-day month overstates hybrid schedules and understates months with weekend shifts. Count expected on-site days, include both directions, and enter parking or tolls as a daily shared fee. The focused calculator shows monthly gas and EV totals and annualizes their difference over 12 equal planning months.
The IRS revised its optional business mileage rate to 76 cents per mile for qualifying travel from July 1, 2026, reflecting broader vehicle costs. Ordinary commuting is generally not deductible; the rate is useful here only as context for why fuel alone is narrower than total vehicle ownership cost.
Use your actual schedule when possible. For a rough estimate, 20 days per month works for a typical five-day workweek with some holidays or time off.
Yes. Add daily parking or tolls to the extras field in the main calculator before multiplying by commute days.
