Sales Forecast Calculator
Forecast MRR using growth and pipeline conversion assumptions.
Result
Combines organic growth with conversion-weighted pipeline additions each month.
Supporting metrics
The headline value alongside the engine's top supporting outputs.
How to use it
- Enter starting MRR, monthly organic growth, pipeline conversion rate, average deal size, new opportunities per month, and forecast months. Use historical close rates and current pipeline generation, not sales targets, because small assumption errors compound every month.
- Read projected MRR at the horizon, cumulative forecast revenue, monthly pipeline contribution, growth rate, and forecast horizon. Pipeline conversion above 40% is flagged because it often produces a forecast that looks precise but is not grounded in real close performance.
- Separate growth driven by compounding from growth driven by pipeline volume. If most of the forecast lift comes from new opportunities times conversion times deal size, the forecast is mainly a sales-capacity bet rather than a durable momentum story.
- Build at least downside, base, and upside cases by moving conversion 5-10 points and opportunity volume 10-20%. Use the downside or base case for hiring and cash planning, and reserve the upside case for stretch goals or investor discussion.
- Re-run monthly as pipeline ages, close rates shift, or deal size changes. Compare forecasted MRR versus actual MRR each month so the model gets calibrated to your true win-rate behavior.
Questions people usually ask
What makes a forecast useful instead of fantasy?
Grounding it in real conversion, growth, or pipeline assumptions you can actually defend. A clean forecast is only as good as the drivers behind it.
Should I trust the total or the monthly path more?
Start with the monthly path. The timing of growth, slippage, and recovery often matters more than the final headline total.
Why should I run downside and upside cases?
Because one forecast number is not a plan. The range tells you how much risk you are really carrying.
Can this replace a full finance model?
No. It is best for fast planning, founder decisions, and scenario pressure-testing before you open a bigger model.
Is this tool free and private to use?
Yes. AI Biz Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
