How to calculate algal growth rate
This calculator finds algal growth rate by dividing final biomass by the growth period — a basic productivity measure used in aquaculture, algae cultivation, and biofuel research.
How the calculation works
Growth rate = Final biomass ÷ Growth time.
Example
125 mg/L of final biomass over a 20-day growth period: Growth rate = 125 ÷ 20 = 6.25 mg/L per day.
Frequently asked questions

Pro Tips for Algal Growth Rate
- Make sure biomass and time units are consistent with how you plan to compare results across different growth conditions or trials.
- This is a simple average rate over the whole period — real growth is often not perfectly linear, with lag, exponential, and stationary phases in a typical growth curve.
Common Algal Growth Rate Mistakes to Avoid
- Treating a simple average growth rate as representative of the entire growth curve, when actual algal growth typically follows lag, exponential, and plateau phases rather than a constant rate.
