# Marketing Investment Ratio (MIR)

**Marketing investment ratio(MIR)** is an indicator calculated by dividing [sales revenue](/roivenue-resources/glossary/marketing-and-financial-glossary/sales-revenue.md) from marketing investment. It’s output approximates how much of your revenue can be accredited to your marketing.

MIR differs for various market segments and companies. If it’s low, it could indicate that a company relies more on its brand’s reputation and the quality of its service. If it’s high, it could indicate that a company invests more towards growth and thus, its [sales revenue](/roivenue-resources/glossary/marketing-and-financial-glossary/sales-revenue.md) may be highly dependent on its level of marketing investment.

Monitor your MIR trends for your sales channels and marketing platforms in Roivenue and try to adjust them to achieve better business results.
