How to use this calculator

  • Enter current monthly recurring revenue.
  • Add the current monthly growth rate.
  • Choose an ARR multiple for the company stage and market.
  • Enter gross margin to assess revenue quality.

What the result means

ARR scale, growth, and margin help investors judge valuation, funding stage, and whether the company can support venture-style returns.

Current ARR = current MRR × 12. Projected ARR = current MRR × (1 + monthly growth rate)^12 × 12. Valuation estimate = current ARR × ARR multiple.

Projected ARR assumes growth compounds steadily for 12 months. Real startup growth is rarely this smooth.

Example calculation

With $80,000 MRR, current ARR is $960,000. At 8% monthly growth, projected ARR after 12 months is about $2.42M.

Tips for better results

  • Compare projected ARR with actual historical cohorts.
  • Use conservative growth assumptions in investor diligence.
  • High ARR with weak margin may deserve a lower multiple.
  • Connect ARR growth with burn efficiency.

FAQ

What ARR do investors expect before Series A?

Expectations vary, but investors usually want meaningful ARR, strong growth, and evidence of repeatable acquisition.

How do investors use ARR multiples?

Investors multiply ARR by a market multiple, then adjust for growth, margin, churn, market size, and risk.

What is a good ARR growth rate for SaaS?

A good ARR growth rate depends on stage, but venture-backed startups are often expected to grow quickly while retaining customers.

How does gross margin affect ARR valuation?

Higher gross margin usually supports stronger valuation because more revenue can convert into contribution profit.

Why is projected ARR important for investors?

Projected ARR helps investors estimate future scale, funding needs, and potential exit value.
