## Hit Ratio Formula

The following formula is used to calculate the Hit Ratio.

**HITR = #H / (#H+#M) * 100**

- Where HITR is the Hit Ratio (%)
- #H is the total number of cache hits
- #M is the total number of cache misses

## How to Calculate Hit Ratio?

The following example problems outline how to calculate Hit Ratio.

Example Problem #1:

- First, determine the total number of cache hits.
- The total number of cache hits is given as: 30.

- Next, determine the total number of cache misses.
- The total number of cache misses is provided as: 15.

- Finally, calculate the Hit Ratio using the equation above:

HITR = #H / (#H+#M) * 100

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

HITR =30 / (30+15) * 100 = 66.667 (%)

Example Problem #2:** **

For this problem, the variables required are provided below:

total number of cache hits = 160

total number of cache misses = 14

Test your knowledge using the equation and check your answer with the calculator above.

HITR = #H / (#H+#M) * 100** = ?**
