Revenue Calculator
Selling 1,200 units at $49 each produces $58,800 in revenue. This revenue calculator multiplies units sold by price per unit to give you that number in seconds, or switches direction to solve for the units or price you need to reach a target. It works for ecommerce products, SaaS seats, service packages, subscription boxes, and any other offer with a clear per-unit price. Revenue is the starting line for staffing plans, inventory orders, and marketing budgets, but it's easy to get the number wrong when you mix time periods or use the wrong price. Enter the two values you already know: in revenue mode that's units sold and price per unit, and in the two reverse modes that's your target revenue plus one known input. The tool returns the missing figure along with the full equation, so you can sanity check a sales forecast, size a pricing test, or work out how many units you need to sell before a deadline.
Quick answer
Revenue equals units sold multiplied by price per unit, the same math retailers, SaaS teams, and service businesses use to turn sales activity into a dollar figure.
What this tells you
- •Revenue equals units sold multiplied by price per unit, the same math retailers, SaaS teams, and service businesses use to turn sales activity into a dollar figure.
- •Switch to reverse mode to solve for the units you need to hit a revenue target when you already know your price, or the price you need when you already know your unit volume.
- •Keep the time basis consistent across every input, such as monthly units with monthly price, or annual seats with annual price, so mixed periods don't distort the result.
- •Use your average realized price, meaning what you actually collect after discounts and credits, rather than list price, if you want the estimate to reflect what typically lands in the bank.
- •Reverse-mode results are often fractional, such as 252.53 seats. Round up when you can only close whole deals, seats, or units, since rounding down leaves you short of the target.
- •This is a planning shortcut. It does not account for taxes, refunds, churn, or revenue recognition timing, so treat the output as a starting estimate, not a finished forecast.
How to Use
- 1Choose whether you want to calculate revenue, required units sold, or required price per unit from the mode selector.
- 2Enter the two values you already know. Revenue mode needs units sold and price per unit. The two reverse modes need your target revenue plus the one input you already have.
- 3Use numbers from the same period and the same product or offer. Mixing monthly units with a quarterly revenue target produces a distorted answer.
- 4Use average realized price rather than list price if discounts, credits, or refunds change what you actually collect per sale.
- 5Calculate to see the missing value along with the full revenue equation, then adjust inputs to compare different pricing or volume scenarios.
How It Works
Formula
Revenue = Units Sold x Price Per Unit
Units Sold = Target Revenue / Price Per Unit
Price Per Unit = Target Revenue / Units SoldRevenue mode multiplies quantity by unit price directly. Units mode rearranges the same equation to solve for the missing unit count by dividing your target revenue by the known price per unit. Price mode solves for the missing price by dividing target revenue by the known unit count. All three modes use the same underlying relationship, just solved for a different unknown. The calculator rounds every value, including units sold, to two decimal places, which is useful for planning but means reverse-mode results can land on a fraction, like 252.53 seats, rather than a whole number you can actually sell.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Monthly ecommerce revenue
An online store that sells 1,200 items at an average realized price of $49 generates $58,800 for that period.
SaaS seat target
At $99 per seat, you need about 252.53 seats to reach $25,000 in monthly revenue. If you only bill whole seats, round that figure up to 253.
Consulting package pricing
If you expect to sell 300 packages in the quarter, an average price of $200 per package reaches $60,000 in revenue.
Neighborhood bakery weekly sales
A bakery that sells 340 items in a week at an average price of $6.50 brings in $2,210 for that week. Multiplying units by price turns a daily or weekly sales count into a dollar figure you can compare against rent, wages, and ingredient costs.
Marketing agency retainer pricing
An agency that wants $48,000 in quarterly revenue from 8 retainer clients needs to price each retainer at $6,000 for the quarter. Reverse mode turns a revenue goal and a client count into the price you need to charge.
Handmade goods shop revenue goal
A shop selling items at $36 each needs to sell 250 units to reach a $9,000 revenue goal for the period. Because this result lands on a whole number, there is no rounding decision to make before setting a sales target.
What counts as price per unit?
Use the average selling price you actually collect per unit, not a list price that never really gets charged. For ecommerce that usually means item price after discounts but before pass-through sales tax. For SaaS it can mean the monthly or annual subscription price per seat, account, or plan, and for services it means the price a client actually pays after any negotiated discount.
If your business sells several plans, tiers, or products at different prices, this calculator works best with a blended average for one period rather than a single list price pulled from one SKU. Divide total revenue by total units for a recent period to back into a realistic blended price before you run reverse-mode scenarios.
Keep the same price definition every time you use the tool. Switching between gross price one month and net price after refunds the next month makes it hard to trust comparisons across periods.
Common mistakes
- Mixing a monthly price with annual units sold or annual revenue targets
- Using list price instead of the average realized price after discounts, refunds, or credits
- Rounding reverse-mode unit results down when you can only sell whole items or seats
- Treating the output as a full forecast instead of a planning estimate, when it ignores taxes, refunds, and churn
- Blending revenue from multiple products or price tiers into a single average price without noting that this hides the real price mix
- Forgetting to switch modes, so a target-revenue value ends up sitting in the price field by mistake
Limitations
This calculator uses a single average price and a single unit count for the period you enter, so it does not model tiered pricing, volume discounts, taxes, shipping, refunds, churn, proration, bundle mix, or revenue recognition timing. It assumes every unit sells at the same average price, which can hide real variation between your highest and lowest priced orders. Reverse-mode results are rounded to two decimal places and can land on a fraction of a unit, such as 252.53 seats, which is not something you can actually sell. Use this tool as a planning shortcut for sizing a target or sanity-checking a pricing assumption, not as a substitute for a full revenue forecast or financial model built from actual sales data.
