A business is a loop: spend on inputs, make something, sell it, collect money, cover costs and start again. Use the buttons to follow money and goods around the cycle.
The revenue-cost cycle is a simple model of how a business keeps itself running. Money goes out to buy inputs, those inputs are turned into something a customer wants, the customer pays for it, and the money comes back in as revenue. That revenue then pays for the next round of inputs — and the loop starts over.
Every business, from a corner shop to a large firm, can be described as some version of this loop. The parts change, but the shape stays the same: spend, produce, sell, collect, cover costs, repeat.
Because a business does not stop after one sale. Each turn of the cycle is meant to feed the next. When revenue reliably covers costs, the loop can grow a little each time. When it does not, the loop shrinks. Seeing the cycle as a loop makes it easy to spot where the money and goods are actually moving.
This diagram strips the idea down to four colour-coded stages and four short flows between them, so the whole pattern fits in one picture.
Every turn of the cycle starts with inputs: the materials, labour and tools a business needs before it can make anything. Money flows out here, and it is the fuel for everything that follows.
The inputs are transformed into goods or services. This is where raw materials and effort become something a customer is willing to pay for. The flow runs from inputs to production.
What was produced is delivered to the customer. Without this step nothing has been sold — the value stays stuck inside the business instead of reaching the person who wants it.
When customers receive the goods or service, they pay. That money comes back into the business as revenue. This is the point where the loop turns money outward-in again.
Revenue then flows back to the input stage to cover the cost of the next round. Whatever remains after costs is profit. Because revenue feeds the next turn, the cycle can run again — and grow, if each turn leaves a little more behind.
It is the repeating loop at the heart of a business: you spend money on inputs, turn them into goods or services, sell them to customers, collect revenue, and then use that revenue to cover the costs of the next round.
No. Revenue is all the money a business takes in from customers. Profit is what is left after the costs of running the business are subtracted from that revenue.
Anything the business must pay to keep producing: materials, labour, tools and equipment, rent, energy and other running expenses. Together these are what revenue has to cover before anything is left over.
A single turn produces one batch of goods or services. To keep trading, the business must reinvest part of the revenue back into inputs, so the same loop runs again and again.
Yes. If costs are higher than the revenue collected, the loop shrinks a little each time. The cycle only sustains itself when revenue at least covers costs.
Not exactly. Revenue is recorded when goods or services are delivered, but the money may arrive later. This simplified diagram treats the flow as one smooth loop so the basic idea is easy to follow.
