Definition
A revenue forecast projects future sales from the inputs you can actually influence: traffic or leads, conversion rate, average order value and repeat purchase. Built bottom-up from those, it becomes a plan you can manage — rather than a growth percentage someone hoped for.
The formula
Revenue = Leads × Close rate × Average order value × (1 + Repeat rate)
Forecast the inputs, not the output. A target of 30% growth tells you nothing about what to do on Monday; a forecast that says you need 240 more leads a quarter at a 12% close rate does.
A worked example
Building a quarter from the inputs
- 1Current: 150 leads a month, 12% close rate, ₹65,000 average order value.
- 2That is 18 customers and ₹11,70,000 a month.
- 3Plan: lift leads to 200 through additional budget, and close rate to 14% by responding faster.
- 4Projected: 28 customers and ₹18,20,000 a month.
A 56% revenue increase from a 33% lead increase and a two-point close-rate gain. Stated that way it becomes two owned tasks rather than an aspiration.
How to move the number
Forecast three scenarios, not one
A single number is a guess. Conservative, base and stretch tell you which decisions are safe under all three, which is the actual purpose of forecasting.
Model the input you can move fastest
Close rate and average order value usually respond faster than lead volume and cost nothing in media. Test their effect on the forecast before assuming you need more budget.
Reforecast against actuals monthly
The value is in the gap between forecast and actual. A forecast never revisited is a document; one corrected monthly is a control system.
Where people get this wrong
- Forecasting a revenue number top-down and then working out afterwards whether it is achievable.
- Assuming conversion rates hold as volume scales — they usually fall as you move into colder audiences.
- Ignoring seasonality in categories where it dominates, such as education admissions or wedding services.
- Never comparing the forecast to what actually happened, which removes the only feedback loop it has.
Revenue Forecast Calculator — questions we get
How far ahead should I forecast?
One to two quarters in detail, with anything beyond that as a direction rather than a plan. Annual forecasts built on today's conversion rates are usually obsolete by month four.
How accurate should a forecast be?
Within about 20% is genuinely good for an SMB. Precision is not the point — the point is knowing which lever to pull when reality diverges.
Should I forecast leads or revenue?
Forecast leads, close rate and order value, and let revenue fall out of them. Those are the things you can actually manage week to week; revenue is only their consequence.
