Log Reduction Calculator
Log Reduction Calculator
Instant Calculation
Solves microbial kill factors and plots exponential decay curves live.
Enter any values below. This calculator uses an Omni-Directional Engine: type freely into any field and the system will automatically solve the missing data based on your newest inputs.
Initial CFU amount
The number of colony-forming units (CFU) present before sterilization or treatment.
Final CFU amount
The number of colony-forming units (CFU) remaining after sterilization or treatment.
Log reduction
A 1 log reduction equals a 90% reduction, a 2 log reduction equals 99%, and so on.
Log
💡 Note: Modifying this outcome parameter will automatically adjust the Initial CFU field above to balance the math.
Percentage reduction
The total percentage of microbes eliminated compared to the initial amount.
