logistic growth model calculator online

Use logistic growth model calculator online for capacity, initial, rate, time. Constant carrying capacity; model parameters are supplied scenarios. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter capacity. Set initial, rate, time. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
capacityMain input. Positive values. 1000
initialOption. Positive values. 10
rateOption. Signed finite values. 0.2
timeOption. Zero or positive values. 10

Calculation method

population = capacity/(1+(capacity/initial-1)*exp(-rate*time)) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply logistic growth model calculator to the case below, keeping the displayed units and assumptions. Constant carrying capacity; model parameters are supplied scenarios.

Logistic Growth Model Calculator — worked case

Settings: initial: 10; rate: 0.2; time: 10

Input:

1000

Calculated result for these inputs:

Output:

{
  "population": 69.45315965638048
}

Choose the right tool

Choose number theory for exact integer relationships, distribution tools for a declared random model, and geometry tools for coordinates. A density is not a probability and a statistical model does not establish a real-world outcome.

Limitations and common mistakes

  • Constant carrying capacity; model parameters are supplied scenarios. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
