What Is a Projected Revenue Calculator?
A Projected Revenue Calculator helps estimate how much revenue a business may generate over a future period based on expected sales, pricing, recurring subscriptions, customer acquisition costs (CAC), refunds, churn, and additional revenue streams. Instead of manually creating formulas in spreadsheets, the calculator performs these calculations instantly and updates the results whenever your assumptions change.
Whether you're launching a startup, managing an eCommerce store, running a SaaS business, or planning future sales, projecting revenue helps you understand potential business performance before making financial decisions. Along with estimating Gross Revenue and Net Revenue, this calculator also measures Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), and Average Revenue Per User (ARPU).

Revenue forecasting helps businesses estimate future income and prepare for important decisions such as pricing products, hiring employees, planning inventory, allocating marketing budgets, and managing cash flow. A reliable projection reduces uncertainty and supports better financial planning.
Looking only at total sales can be misleading because it ignores acquisition costs, refunds, customer churn, and expansion revenue. A complete revenue forecast provides a clearer picture of expected business performance rather than simply measuring sales volume.
- Estimate future sales revenue before launching a product.
- Forecast subscription income using MRR and ARR.
- Measure Average Revenue Per User (ARPU).
- Evaluate Customer Acquisition Cost (CAC).
- Understand how refunds and churn reduce revenue.
- Compare different pricing strategies before implementation.
- Create realistic financial projections for investors or business planning.
How to Use the Projected Revenue Calculator
- Select your preferred currency.
- Enter the selling price of each product or subscription.
- Specify the expected number of customers or sales.
- Optionally include upsell revenue, customer acquisition cost (CAC), and refund or churn percentage.
- Review the calculated Gross Revenue, Net Revenue, Expansion Revenue, MRR, ARR, and ARPU.
- Adjust different values to compare multiple business scenarios.
Revenue Projection Formula
This calculator follows commonly used business forecasting formulas to estimate future revenue.
- Gross Revenue
Selling Price × Sales Volume - Expansion Revenue
Upsell Value × Sales Volume - Refund & Churn Loss
(Gross Revenue + Expansion Revenue) × Refund Rate - Total Customer Acquisition Cost (CAC)
Customer Acquisition Cost × Total Customers - Net Revenue
Gross Revenue + Expansion Revenue − Refund & Churn Loss − Total CAC - Average Revenue Per User (ARPU)
Net Revenue ÷ Total Customers
Revenue Metrics Explained
| Metric | Meaning | Why It Matters |
|---|---|---|
| Gross Revenue | Total sales before deductions. | Measures overall sales performance. |
| Net Revenue | Revenue after refunds and acquisition costs. | Shows realistic business income. |
| MRR | Monthly recurring subscription revenue. | Tracks recurring business growth. |
| ARR | Annual recurring subscription revenue. | Measures long-term recurring income. |
| ARPU | Average revenue generated per customer. | Evaluates customer value and pricing. |
Revenue Projection Example
Suppose you sell a software subscription for $100 per month and expect 500 customers. Each customer purchases an average $20 upsell, refund rates are 5%, and customer acquisition costs average $15 per customer. The calculator estimates your expected revenue as shown below.
| Metric | Example Value |
|---|---|
| Price per Customer | $100 |
| Expected Customers | 500 |
| Gross Revenue | $50,000 |
| Expansion Revenue | $10,000 |
| Refund & Churn Loss | $3,000 |
| Total CAC | $7,500 |
| Projected Net Revenue | $49,500 |
| ARPU | $99 |
This example demonstrates how customer acquisition costs and refunds reduce net revenue even when gross sales remain strong. Testing different scenarios can help businesses choose the most profitable pricing strategy.
Gross Revenue vs Net Revenue
| Gross Revenue | Net Revenue |
|---|---|
| Total sales before deductions. | Revenue after deductions. |
