How to use this calculator

Enter current MRR, expected monthly MRR growth, annual recurring discounts, and the projection period.

The calculator estimates current ARR run-rate and future ARR if the monthly growth rate continues.

What the result means

ARR translates monthly subscription revenue into an annualized view. At pre-seed, projected ARR should be treated as a scenario, not a guaranteed result.

ARR Run Rate = Current MRR × 12 − Annual Discounts; Projected MRR = Current MRR × (1 + Monthly Growth)^Months; Projected ARR = Projected MRR × 12.

High projected ARR is useful only when churn, discounts, and customer concentration are understood.

Example calculation

With $3,255 MRR, 12% monthly growth, and $1,200 annual discounts, current ARR run-rate is $37,860. After 12 months, projected ARR is about $152,077.

Tips for better results

  • Use conservative growth assumptions when preparing investor materials.
  • Do not include one-time implementation fees in ARR.
  • Show current ARR separately from projected ARR.
  • Update projections monthly as real MRR data arrives.

FAQ

How do I calculate ARR from pre-seed MRR?

Multiply current MRR by 12 and subtract annualized discounts or recurring credits to estimate ARR run-rate.

Can I use projected ARR in a pre-seed fundraising deck?

You can show projected ARR as a scenario, but it should be clearly labeled and supported by growth, churn, and pipeline assumptions.

What is the difference between ARR run rate and projected ARR?

ARR run rate annualizes current MRR, while projected ARR estimates future annualized revenue based on growth assumptions.

Should one-time setup fees be included in ARR?

No. ARR should include recurring subscription revenue, not one-time setup, consulting, or implementation fees.

How fast should pre-seed ARR grow month over month?

Growth expectations vary, but investors usually look for consistent recurring revenue expansion and improving retention rather than one isolated high-growth month.
