The three inputs multiply, so modest improvements in each produce a larger result than any one of them alone. Traffic growth costs money every month; conversion and order value improvements are one-off work that keeps paying.

How the Revenue Projection Calculator works

Traffic, conversion and order value multiply, so modest improvements in each produce more than any one alone. Traffic growth costs money every month; conversion and order value improvements are one-off work that keeps paying.

Also known as: project future revenue · revenue growth projection · forecast annual revenue

Projecting from the drivers

Revenue is a product of components, and projecting the components separately produces a more defensible number than projecting the total.

For a direct channel: sessions times conversion rate times average order value. Each can be forecast from its own history and its own drivers, and each can be questioned separately.

The discipline this imposes is useful. A projection of 40% revenue growth becomes a projection that traffic will grow 25% while conversion improves from 2.1% to 2.3%, which is a set of specific claims that can be argued with rather than a number that cannot.

New and returning customers

Splitting the projection between new and returning customers is worth the extra work, because the two behave completely differently.

New customer revenue is a function of acquisition spend and cost per acquisition, and it stops when the spend stops. Returning customer revenue is a function of the existing base, its repeat rate and its purchase frequency, and it continues.

A business whose growth comes entirely from new customers has to keep spending to stay level, and its projection should show that. One with a growing repeat base has revenue that compounds, and the projection should show that too. Aggregating them hides the difference, which is the most important thing about the business.

Cohorts, and what they reveal

A cohort analysis groups customers by when they first bought and tracks what each group spends over time. It is the clearest picture available of whether a business is getting better or worse.

Improving cohorts, where recent groups spend more in their first year than older groups did, means the product, the site or the marketing is improving. Declining cohorts mean the opposite, and they can be hidden entirely by growing acquisition.

That last point is why cohorts matter. A business can show strong revenue growth while every cohort performs worse than the last, because volume is masking quality. The revenue projection built on aggregate figures will look fine right up until acquisition becomes expensive.

The channel view

Projecting revenue by channel is necessary once there is more than one, because channels have different growth constraints and different economics.

Marketplace revenue is constrained by the marketplace's traffic and by competition on it. Paid acquisition is constrained by budget and by rising costs at scale. Organic search grows slowly and compounds. Email depends on list size and health.

A projection that shows all channels growing at the same rate has not thought about any of them. The realistic version has different rates and different assumptions per channel, and it usually shows that the largest channel is also the one with the least headroom.

The gap between projection and cash

A revenue projection is not a cash projection and the difference is where businesses get into trouble.

Revenue projected for October requires stock bought in July, paid for in June. The cash goes out four months before the revenue arrives, and a projection showing a strong autumn says nothing about whether the business can fund it.

Which is why the revenue projection should feed a cash forecast rather than standing alone. The sequence is: project revenue, derive the stock requirement, derive the payment timing, and produce the cash position. Businesses that stop at the first step routinely plan growth they cannot fund.

Where to go next

The Revenue Projection question rarely arrives on its own. These are the ones that usually come with it:

Sales Forecast Calculator — Plan stock and cash against the peak.
Conversion Rate to Revenue Calculator — What a CRO budget should be measured against.
Sales Growth Target Calculator — Retention and acquisition are substitutes here.
Etsy Fee Calculator — Every Etsy fee on one sale, itemised.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price, check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

How do I project ecommerce revenue?

Sessions times conversion rate times average order value. Projecting each forward separately is more honest than growing revenue as a single number.

Why model the three separately?

Because they have different costs and different ceilings. Traffic is bought, conversion is built, and order value is designed, treating them as one number hides which is doing the work.

What growth rates are realistic?

Whatever you have actually achieved, adjusted for what changes. Projecting a rate you have never sustained produces a plan that fails for reasons the model already contained.

How do I use the projection?

For stock, cash and hiring decisions. A revenue projection with no operational consequence is an exercise; one that drives a purchase order is a plan.
