Formula Used

  • Closed Deals = Leads × Conversion Rate
  • Discounted Deal Value = Average Deal Value × (1 − Discount Rate)
  • New Revenue = Closed Deals × Discounted Deal Value × Seasonality Multiplier
  • Repeat Revenue = Previous Month Net Revenue × Repeat Revenue Rate
  • Upsell Revenue = New Revenue × Upsell Rate
  • Net Revenue = Gross Revenue − Refunds − Churn Loss
  • Profit = Net Revenue − Fixed Cost − Commission − Variable Cost

Frequently Asked Questions

1. What does this calculator estimate?

It estimates monthly net revenue and profit using lead volume, conversion, pricing, repeat sales, upsells, churn, refunds, seasonality, and cost assumptions.

2. Why use seasonality multipliers?

Seasonality helps reflect demand swings across the year. Higher multipliers boost projected revenue for strong months, while lower values reduce projections for slower periods.

3. What is repeat revenue in this model?

Repeat revenue is an added percentage of the previous month’s net revenue. It helps model renewals, repeat orders, or returning customers.

4. How is churn handled?

Churn is treated as a loss tied to the previous month’s net revenue. It reduces current projections to reflect lost customers or reduced account activity.

5. Does the calculator estimate profit too?

Yes. It subtracts fixed monthly costs, commission expenses, and variable costs from projected net revenue to estimate monthly and total profit.

6. Can I use it for multiple scenarios?

Yes. Rename each scenario, change assumptions, and recalculate. This makes it easy to compare conservative, balanced, and aggressive projections.

7. What does break-even month mean here?

It is the first projected month where cumulative profit becomes positive. If costs remain higher than profits, the tool shows that break-even was not reached.

8. Why export CSV or PDF reports?

Exports help you share forecasts with managers, track scenario changes, archive assumptions, and use projection tables in spreadsheets or presentations.
