Calculate cache hit rate
Cache hit rate shows how often requests are served from cache instead of the origin or backend. Enter cache hits and cache misses to calculate hit rate, miss rate and total cacheable requests. It is useful for CDN reviews, API cache checks, site performance work and infrastructure dashboards.
Hits versus misses
A higher hit rate often reduces backend load, but the right target depends on content freshness and cache strategy.
Frequently asked questions
What is cache hit rate?
It is cache hits divided by cache hits plus misses.
Should uncacheable requests be included?
Usually no. Use cacheable requests when measuring cache efficiency.
Is 100 percent hit rate always best?
Not always. Dynamic or fresh content may need lower cache duration.
