Enter the total cost ($) and the total horsepower (hp) into the Calculator. The calculator will evaluate the Cost Per Hp. 

Cost Per Hp Formula



  • CPHP is the Cost Per Hp ($/hp)
  • TC is the total cost ($)
  • HP is the total horsepower (hp)

To calculate Cost Per Hp, divide the cost by the total horsepower gained.

How to Calculate Cost Per Hp?

The following steps outline how to calculate the Cost Per Hp.

  1. First, determine the total cost ($). 
  2. Next, determine the total horsepower (hp). 
  3. Next, gather the formula from above = CPHP = TC / HP.
  4. Finally, calculate the Cost Per Hp.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total cost ($) = 500

total horsepower (hp) = 30


What factors can affect the cost per horsepower when purchasing a vehicle or machinery?

Several factors can influence the cost per horsepower, including the brand, model, age, fuel efficiency, and technological features of the vehicle or machinery. Market demand and availability can also play significant roles in determining the overall cost.

Is a lower cost per horsepower always better when comparing vehicles or machinery?

Not necessarily. While a lower cost per horsepower may indicate a more cost-effective purchase in terms of power output, it’s also important to consider other aspects such as reliability, fuel efficiency, maintenance costs, and overall performance. Balancing these factors is key to making a well-rounded decision.

How can understanding the cost per horsepower benefit consumers?

Understanding the cost per horsepower can help consumers make more informed decisions by comparing the power efficiency of different vehicles or machinery relative to their price. This metric can be particularly useful for individuals looking to maximize performance without overspending.

Can the cost per horsepower calculation be applied to electric vehicles or machinery?

Yes, the concept of cost per horsepower can also be applied to electric vehicles or machinery. However, since electric models use kilowatts (kW) as a measure of power instead of horsepower (hp), the calculation might require conversion between these units (1 hp is approximately equal to 0.7457 kW) to ensure accurate comparisons.
