Enter the volume at IVC and the volume at TDC into the Dynamic Compression Ratio Calculator. The calculator will evaluate and display the Dynamic Compression Ratio.

## Dynamic Compression Ratio Formula

The following formula is used to calculate the Dynamic Compression Ratio.

DCR = IVC / TDC
• Where DCR is the Dynamic Compression Ratio (IVC:TDC)
• IVC is the volume at IVC
• TDC is the volume at TDC

To calculate the dynamic compression ratio, divide the volume at IVC by the volume at TDC.

## How to Calculate Dynamic Compression Ratio?

The following example problems outline how to calculate Dynamic Compression Ratio.

Example Problem #1:

1. First, determine the volume at IVC.
• The volume at IVC is given as: 30.
2. Next, determine the volume at TDC.
• The volume at TDC is provided as: 40.
3. Finally, calculate the Dynamic Compression Ratio using the equation above:

DCR = IVC / TDC

The values given above are inserted into the equation below and the solution is calculated:

DCR = 30 / 40 = .75 (IVC:TDC)

Example Problem #2:

For this problem, the variables required are provided below:

volume at IVC = 60

volume at TDC = 20
