The next step is to identify your key performance indicators (KPIs), which are the metrics that measure your progress towards your revenue goals. Your KPIs should be aligned with your revenue model and strategic objectives and should satisfy the criteria of being specific, measurable, achievable, relevant, and time-bound (SMART). Examples of KPIs for revenue forecasting include revenue, revenue growth, revenue per customer, customer acquisition cost, customer lifetime value, customer retention rate, conversion rate, and return on investment. These metrics provide insight into the total amount of money you receive from revenue sources in a given period, the percentage change in revenue from one period to another, the average amount of money you receive from each customer in a given period, the total cost of acquiring a new customer, the total amount of money you expect to receive from a customer over their relationship with your organization, the percentage of customers who continue to buy from you or support you in a given period, the percentage of prospects who become customers or donors after engaging with your marketing or sales activities, and the ratio of net profit to total investment for a specific activity or program.
