What Is a Revenue Calculator?
A revenue calculator is an online tool that computes your total income from selling products, running a subscription service, or billing for professional services — before any expense deductions. Unlike a profit calculator (which subtracts costs), a revenue calculator focuses purely on the top line: how much money flows into the business from customer transactions.
This tool supports three modes. Product Sales mode multiplies units sold by price per unit, applies an optional discount, and calculates tax to give you gross revenue, net revenue, and annualized projections. Subscription mode computes Monthly Recurring Revenue (MRR), applies a monthly churn rate over a multi-month period, and outputs Annual Recurring Revenue (ARR). Services mode calculates from hourly rate × hours per week × number of staff, showing daily, weekly, total, and annualized revenue. All modes include a scenario table showing revenue at 50%, 75%, 100%, 125%, and 150% of current volume.
How to Use the Revenue Calculator
- Choose a mode — Product Sales for physical or digital goods, Subscription for recurring billing models, or Services for hourly or time-based work.
- Select your currency from the dropdown ($, €, £, ¥, ₹, A$, C$).
- Enter your core numbers: in Product Sales mode, provide Units Sold and Price per Unit (required), plus optional Discount % and Tax Rate. In Subscription mode, enter Subscribers and Monthly Price per Subscriber (required), plus optional Period, Churn Rate, and Tax. In Services mode, enter Hourly Rate and Hours per Week (required), plus optional Weeks, Staff Count, and Tax.
- Click Calculate Revenue to see your revenue category badge, key metric cards, and full breakdown.
- Review the breakdown panel to see how discounts and tax reduce gross revenue to net revenue and revenue after tax.
- Use the scenario table to forecast revenue at different volumes — invaluable for sales targets, subscription growth plans, and capacity planning.

How the Revenue Calculator Works
Product Sales mode uses straightforward multiplication. Gross Revenue equals Units Sold times Price per Unit. A percentage discount is applied to reduce gross revenue to net revenue. Tax (VAT or sales tax) is then applied to net revenue to arrive at the after-tax figure. The annualized estimate multiplies net revenue by 12 (assumes monthly sales cadence):
Subscription mode computes revenue month by month, applying the churn rate each month to the starting subscriber count. This means revenue decreases if churn > 0%, simulating real subscription decay. MRR is the Month 1 revenue; ARR is the annualized equivalent of the full-period revenue:
Services mode calculates from time and rate. Weekly revenue is hourly rate times billable hours per week times number of staff. Total revenue is weekly revenue times the number of weeks in scope. An annualized view extrapolates to 52 weeks:
The scenario table applies multipliers of 0.5×, 0.75×, 1.0×, 1.25×, and 1.5× to your current units, subscribers, or hours to show how revenue scales at different volumes — useful for setting targets, modeling growth, and stress-testing financial plans.
Key Revenue Metrics Explained
Gross Revenue
The total value of all sales before any deductions — discounts, returns, taxes. It represents the maximum top-line figure your business generates.
Units × PriceNet Revenue
Gross revenue minus discounts and allowances. This is the actual revenue recognized after commercial deductions and is the standard 'revenue' figure on financial statements.
Gross Revenue − DiscountsRevenue After Tax
Net revenue after deducting sales tax or VAT. Important for businesses that collect and remit VAT — the tax collected is not actually income for the business.
Net Revenue × (1 − Tax Rate %)MRR (Monthly Recurring Revenue)
The predictable revenue generated each month from active subscribers. MRR is the fundamental metric for subscription businesses — it determines burn rate, payback period, and valuation multiples.
Subscribers × Price/SubscriberARR (Annual Recurring Revenue)
MRR multiplied by 12. ARR is the annual equivalent of your subscription revenue stream, used in SaaS valuations and financial projections. ARR ignores churn and is a forward-looking metric.
MRR × 12Churn Rate
The percentage of subscribers who cancel each month. Even a 2% monthly churn compounds to a ~22% annual churn. High churn can dramatically reduce total subscription revenue over a 12-month period.
Lost Subscribers ÷ Starting Subscribers × 100Annualized Revenue
A projection of annual revenue based on current performance. For product sales: Net Revenue × 12. For services: Weekly Revenue × 52. Useful for comparing performances across different measurement periods.
Period Revenue ÷ Period × 12 (or × 52)Revenue per Unit
The average revenue generated per unit sold, per subscriber, or per billable hour. Tracking this over time reveals pricing power, discount trends, and customer upgrade patterns.
Net Revenue ÷ VolumeFrequently Asked Questions
What is the difference between revenue and profit?
Revenue is the total money generated from sales before any costs are deducted — it's the "top line" on an income statement. Profit is what remains after subtracting all costs (COGS, operating expenses, taxes) — it's the "bottom line". A business can have high revenue but zero (or negative) profit if costs are too high.
What is the difference between gross revenue and net revenue?
Gross revenue is the total sales value before any deductions. Net revenue removes discounts, promotional allowances, and returns from gross revenue. Net revenue is the figure reported as "Revenue" on formal financial statements under GAAP and IFRS.
What is MRR and why does it matter?
MRR (Monthly Recurring Revenue) is the predictable, normalized monthly revenue from active subscriptions. It's the lifeblood metric for SaaS and subscription businesses because it determines cash flow predictability, subscriber lifetime value, and is the primary input for valuation models (typically 5–15× ARR for high-growth SaaS companies).
What is a good churn rate for a subscription business?
For B2B SaaS, monthly churn below 1% (< 12% annually) is considered healthy. For B2C subscriptions, 3–5% monthly churn is more common. Even a 2% monthly churn compounds to ~22% annual churn — meaning you lose roughly 1 in 5 customers per year, requiring constant new subscriber acquisition to maintain revenue.
How do I calculate annual recurring revenue (ARR) from MRR?
ARR = MRR × 12. For example, if you have 500 subscribers paying $50/month, your MRR is $25,000 and your ARR is $300,000. Note: ARR ignores churn — it represents the annualized value of your current subscriber base if no one churns. Use our subscription mode with churn rate to model realistic annual revenue.
How do I calculate hourly service revenue for multiple staff?
Use Services mode: enter your hourly billing rate, billable hours per week, and the number of staff. Weekly Revenue = Hourly Rate × Hours/Week × Staff Count. For example, a 3-person team billing $120/hour for 35 hours/week each generates $12,600/week and $655,200/year.
What's the difference between revenue and turnover?
In most contexts, "turnover" and "revenue" are used interchangeably — both refer to total income generated from business activities before deducting any costs. In the UK and Australia especially, "turnover" is the preferred term. The US accounting standard uses "revenue" or "net sales".
How does a discount affect revenue?
A discount reduces gross revenue to net revenue. For example, offering 10% off on $100,000 in gross sales reduces net revenue to $90,000 — a $10,000 reduction. While discounts can increase volume, they must increase it proportionally to maintain total net revenue. Use this calculator's scenario table to see how much volume growth you need to offset a discount.
