Kafka Partition Calculator
Calculate the optimal number of Kafka partitions based on throughput requirements, consumer parallelism, and latency goals for production-ready deployments.
Configuration
Total write throughput required
Typical: 5-15 MBps per partition
For consumer parallelism
Low latency requires more partitions (x1.1)
Recommended: 3 for production
Safety margin for growth

How to Calculate Kafka Partitions
Determining the right number of partitions for Apache Kafka topics is crucial for achieving optimal performance. Our calculator uses the industry-standard formula that considers several key factors:
Throughput-Based Calculation
Base partition count = Target Throughput ÷ Partition Throughput Capacity
- • Considers producer write speed
- • Accounts for consumer read capacity
- • Includes replication overhead
Latency Optimization
Lower latency requirements may need additional partitions for parallel processing.
- • Ultra-low: 1.5-2x multiplier
- • Low: 1.2-1.5x multiplier
- • Standard: 1x multiplier
