How to use this calculator

  • Enter current MRR from recurring subscriptions.
  • Add expected monthly growth and churned MRR to produce a practical projection.
  • Enter employee count to estimate ARR efficiency.

What the result means

ARR is the annualized recurring revenue base. Seed-stage investors usually evaluate ARR together with growth rate, retention, burn, and efficiency rather than ARR alone.

Current ARR = Current MRR × 12. Projected MRR = Current MRR × (1 + Growth Rate) - Churned MRR. Projected ARR = Projected MRR × 12.

ARR should exclude setup fees, consulting revenue, and non-recurring implementation income.

Example calculation

If MRR is $25,000 and expected monthly growth is 10% with $1,000 churned MRR, projected monthly MRR becomes $26,500 and projected ARR becomes $318,000.

Tips for better results

  • Use subscription revenue only.
  • Track ARR per employee as efficiency improves.
  • Pair ARR growth with runway and burn multiple.
  • Use conservative projections for fundraising planning.

FAQ

What ARR do seed startups need before raising Series A?

The target varies by market, but Series A readiness usually requires meaningful ARR growth, strong retention, and evidence of repeatable acquisition.

How do I calculate ARR from MRR for a seed startup?

Multiply qualified monthly recurring revenue by 12. Exclude one-time services, pilots without recurring commitment, and non-recurring implementation fees.

What ARR growth rate do SaaS investors expect at seed stage?

Investors often look for strong month-over-month growth, but growth quality matters more when churn is low and customer acquisition is repeatable.

How does ARR affect startup valuation?

ARR often drives revenue multiple valuation, but the multiple depends on growth, retention, market quality, margin, and burn efficiency.

Should a seed startup focus on ARR or user growth?

A B2B SaaS startup usually benefits from focusing on ARR and retention, while user growth matters only if it converts into durable recurring revenue.
