The short version
- Use a realistic MPG value for the vehicle you are driving.
- Update the gas price when your actual pump price changes materially.
- Treat the result as an estimate, not a complete cost-of-driving figure.
The simple gas-cost formula
Divide miles driven by your vehicle’s miles per gallon, then multiply the gallons by the current price per gallon. The No Tipper gas estimator uses the same three inputs.
Example: a 24-mile shift segment
For an illustrative 24-mile segment in a vehicle averaging 24 MPG with gas at $3.40 per gallon: 24 ÷ 24 × $3.40 = $3.40 in estimated gas.
On the same numbers, $3.40 ÷ 24 is about 14.2 cents per mile. That per-mile figure lets you compare an estimate across vehicles or gas prices, and it is still an estimate.
Real fuel use changes with traffic, idling, weather, vehicle condition, and driving style. That is why No Tipper labels the number as an estimate.
Keep the inputs useful
Use a recent MPG figure rather than the best number printed for the vehicle. Update the gas price when you refill, then compare estimates across trips using the same method. Keep the shift distance in the DoorDash mileage log, and use the odometer and fuel-log guide to record those inputs, distinguish a shift estimate from a fill-to-fill measurement, and combine unequal-distance rows.
The estimate does not include maintenance, insurance, depreciation, tolls, or other driving costs. Keep those decisions separate from the gas calculation.
Can a fuel estimate show the total trip cost?
No. No Tipper estimates gasoline from miles, MPG, and price per gallon; total driving cost can also include maintenance, insurance, depreciation, tolls, parking, and time. Use the 72-mile driving-cost example when the decision needs those broader lines.
Trip details, fuel estimates, messages, and exports in one place.
No Tipper is an iOS app for delivery drivers that records trip time and mileage, estimates gas cost from vehicle inputs, prepares rule-based customer messages, and exports trip records as CSV or PDF through No Tipper Pro.
Free to download. No Tipper Pro unlocks unlimited saved trips, CSV/PDF export, and custom message templates for $1.99/month or $19.99/year in the US. Plans auto-renew; cancel in Apple Subscriptions. Confirm any trial eligibility in the app.
Common questions
How do I estimate fuel cost from my delivery miles?
Divide your delivery miles by your vehicle’s MPG, then multiply by the price per gallon. No Tipper uses those same inputs to estimate fuel cost alongside a trip record. The result is a fuel estimate, not the complete cost of driving.
Does the estimate include idling?
The estimate is based on miles, MPG, and gas price, so unusual idling or traffic can make actual fuel use differ.
Is estimated gas cost the same as total vehicle cost?
No. It is a fuel estimate only and does not include maintenance, depreciation, insurance, tolls, or other expenses.
