Accuracy Notes
Every DOT Per Diem Calculator on CalcIntel uses a documented formula. Results are estimates, real outcomes depend on assumptions and market conditions not captured in a simplified calculation.
Formula
Simple interest:
I = P × r × t
Where P is principal, r the annual rate (decimal), and t the time in years. Balance at the end = P + I.
When to Use This Calculator
- Compare two vehicles, fuels, or financing offers on total cost of ownership.
- Forecast monthly cost for a commute, lease, or road trip.
- Decide whether a repair or trade-in is the better move.
Limitations & Common Mistakes
- Fuel economy numbers are EPA estimates; real-world mileage varies with driving style, weather, and terrain.
- Total cost of ownership should also include insurance, maintenance, registration, and depreciation.
