Calculadora de Taxa de Retenção de Cliente

The Customer Retention Rate Calculator measures the proportion of customers who continue to buy or use your services over a specific period. It is essential for subscription-based businesses, SaaS, e-commerce, or any company relying on long-term relationships. The rate is calculated by subtracting new customers acquired in the period from the total customers at the end, dividing by the number of customers at the start, and multiplying by 100. The result is a percentage indicating the effectiveness of your retention strategy.

To use the calculator, enter the number of customers at the beginning of the period, the number at the end, and how many new customers were acquired during that interval. The tool applies the formula automatically and displays the retention percentage. For example, if you started the month with 200 customers, ended with 220, but acquired 40 new ones, your retention is (220 - 40) / 200 * 100 = 90%. This means 90% of existing customers stayed, while 10% were lost.

When to use? Whenever you want to assess business health and customer lifetime value. It is useful after marketing campaigns, price changes, product launches, or seasonal periods. High retention indicates satisfaction and loyalty, while low retention suggests issues like poor service, competition, or product mismatch. Monitor the rate monthly or quarterly to identify trends.

Cautions: The formula assumes all customers at the start are the same throughout the period, except for new ones. If there are reactivations of old customers, treat them as new. Also, the rate does not distinguish between inactive and active customers; clearly define what a 'retained customer' means (e.g., made at least one purchase in the period). Avoid comparing rates of periods with different durations without normalizing.
