Formula Nature & Mechanics
Exponential Compounding Growth: Returns generate subsequent returns over time t, rapidly accelerating capital growth.
Common Mistakes & Traps
- Entering annual percentage rate (e.g. 7%) as 7 instead of converting to decimal 0.07.
- Neglecting the compounding frequency (n): monthly compounding produces higher yield than annual.
- Ignoring inflation drag when evaluating long-term nominal returns.

Worked Example: Fuel Cost
Given:
- distance = 450
- efficiency = 15
- price = 105
- Fuel needed = 450 km ÷ 15 km/L = 30 L
- Cost = 30 L × $105 = $3,150
- Cost per km = $7
Answer: 3150
Frequently Asked Questions
What is the Fuel Cost formula?
Cost = (Distance ÷ Efficiency) × Price per litre. Trip fuel cost from distance, your vehicle's fuel efficiency and the fuel price.
How do I calculate Fuel Cost?
Enter Trip Distance (distance), Fuel Efficiency (efficiency), Fuel Price per Litre (price) into the calculator. It applies Cost = (Distance ÷ Efficiency) × Price per litre and shows every step of the working.
