Slovin’s Formula Calculator

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 + Ne²)

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:
