Enter the initial price, monthly maintenance cost, and total number of months into the calculator to determine the total cost of the headphones. This calculator can also evaluate any of the variables given the others are known.

## Headphone Formula

The following formula is used to calculate the total cost of headphones over a period of time.

TC = P + (M * N)

Variables:

- TC is the total cost of the headphones P is the initial price of the headphones M is the monthly maintenance cost N is the total number of months

To calculate the total cost of the headphones, multiply the monthly maintenance cost by the total number of months. Add this result to the initial price of the headphones.

## What is a Headphone?

A headphone is a pair of small loudspeaker drivers worn on or around the head over a user’s ears. They are electroacoustic transducers, which convert an electrical signal into a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. They are also known as earphones or, colloquially, cans.

## How to Calculate HeadphonesCost?

The following steps outline how to calculate the Total Cost of the headphones using the formula: TC = P + (M * N).

- First, determine the initial price of the headphones (P).
- Next, determine the monthly maintenance cost (M).
- Next, determine the total number of months (N).
- Next, insert the values of P, M, and N into the formula TC = P + (M * N).
- Finally, calculate the Total Cost of the headphones (TC).
- After inserting the variables and calculating the result, check your answer with a calculator.

**Example Problem:**

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

Initial price of the headphones (P) = $100

Monthly maintenance cost (M) = $5

Total number of months (N) = 12
