Given a ten% annual fee of return, how lengthy will it take to your cash to double? Take 72 and divide it by 10 and also you get 7.2. This implies, at a ten% fastened annual fee of return, your cash doubles each 7 years.

That’s the ability of compound curiosity—what makes investing an unimaginable strategy to develop your wealth over time.

## When to Use the Rule of 72
