Cash flow & working capital

Revenue growth forecast calculator

A forecast is only as good as its assumptions, but seeing the compounding effect of a growth rate against a fixed cost base is often enough to change a plan.

  • Growth consumes working capital — fund the gap before the revenue arrives.

How to use this calculator

  1. 1Enter current annual revenue, gross margin and fixed costs.
  2. 2Set an annual growth rate and cost inflation rate.
  3. 3Choose the number of years to project.

Compounding cuts both ways

Revenue growing 15% a year roughly doubles in five years. Fixed costs growing 8% over the same period barely rise 47%, which is why disciplined growth expands margin without any pricing change.

The reverse is equally true: a 5% annual decline erases a quarter of revenue in five years while overheads stay stubbornly flat.

Sanity-checking a forecast

Tie growth to a capacity constraint: staff, leads, machine hours or delivery capacity. A revenue line that outruns capacity is a wish, not a forecast.

For valuation work, buyers discount forecast years heavily. A DCF built on unfounded hockey-stick growth simply gets a higher discount rate applied to it.

Frequently asked questions

How many years should I forecast?

Three years for operating plans, five for a valuation model. Beyond that, terminal assumptions dominate the result.

Should growth be flat across years?

Rarely, but a constant rate is a useful base case. Model a lower rate in later years to reflect market saturation.

Does the forecast include working capital?

No. Growth also consumes cash through receivables and stock — use the working capital and cash conversion cycle tools alongside this one.
