ROMI

ROMI (Return on Marketing Investment) is a metric used to evaluate the effectiveness of marketing campaigns, showing the profit generated from promotional investments. Unlike the general ROI (Return on Investment), which considers profit from all investments, ROMI focuses exclusively on advertising expenses.

ROMI is an assessment of the profitability of a specific marketing campaign. The main difference from many other metrics is that calculations are made based solely on the advertising budget, rather than the overall company expenses (such as production, storage, or team wages). It clearly shows how effectively advertising resources are used and whether the expenditures were justified.

What is ROMI used for?

ROMI helps businesses understand which marketing tools truly bring results and which cause losses. This is important for:

• optimizing and reallocating resources properly;
• making strategic decisions and identifying the most effective promotion channels;
• justifying marketing expenses and demonstrating the effectiveness of the chosen strategy.

With ROMI, you can assess how much marginal profit remains after accounting for advertising costs.

How to calculate ROMI?

First, determine the revenue for a certain period and compare it to the marketing budget. For example, if a company spent $1,000 on product promotion and generated an additional $5,000 in profit, the formula would be:

(Marginal Profit – Marketing Costs) / Marketing Costs × 100%

For this example: (5000 – 1000) / 1000 × 100% = 400%.

This means that for every dollar spent on advertising, the company gained $4 in marginal profit.

There is also a simplified formula:

Additional Profit / Advertising Costs × 100%.

This version can be more convenient for quick calculations.

What is considered a good result?

The starting point is 0. This allows evaluating the effectiveness of the campaign:

• less than 0 – the advertising is unprofitable, expenses are not justified, and the budget is spent inefficiently;
• 0 – the advertising broke even; this may be acceptable in the early stages of a campaign;
• above 0 – a great result that confirms the efficiency of advertising investments.

ROMI is important not only for marketers but also for executives and financial analysts who assess the feasibility of marketing investments. It helps judge the productivity of advertising strategies and the justification of expenses.

It’s also important to consider market specifics. For example, for consumer goods, the decision-making cycle is short, so ROMI can be evaluated quickly. However, for premium or expensive products, the impact of an advertising campaign may take months to show. In such cases, a low ROMI might be acceptable if the results manifest in the long term.
