In statistics, **Slovin’s Formula** is used to calculate the minimum sample sized needed to estimate a statistic based on an acceptable margin of error.

Slovin’s formula is calculated as:

n = N / (1 + Ne^{2})

where:

- n = sample size
- N = population size
- e = acceptable margin of error

To use Slovin’s formula, simply enter the population size and acceptable margin of error below and then click the “Calculate” button:

**Population Size (N):**

**Acceptable Margin of Error (e):**

Sample size (n): **200.000**
