How do I calculate ARR if I already know my current MRR?

Use the basic SaaS formula: take your latest stable Monthly Recurring Revenue and multiply by 12, so the calculator applies [math]ARR = MRR \times 12[/math] to annualize your current run rate. :contentReference[oaicite:0]{index=0}

How should I use the “Customers × ARPU (monthly)” and “Customers × ACV (annual)” modes?

In “Customers × ARPU (monthly)”, ARR is estimated as [math]ARR = \text{Customers} \times \text{Monthly ARPU} \times 12[/math]. In “Customers × ACV (annual)”, ARR is [math]ARR = \text{Customers} \times \text{ACV}[/math], which the tool then converts to MRR for you. :contentReference[oaicite:1]{index=1}

Does ARR in this calculator include one-time setup fees or services?

No—ARR should capture only predictable subscription revenue. One-off onboarding, consulting, or implementation fees are normally excluded so your ARR reflects true recurring revenue quality. :contentReference[oaicite:2]{index=2}

How can I use the ARR and MRR outputs for investor or valuation discussions?

Investors look at both the absolute ARR and its growth rate; higher, consistent ARR growth usually commands better valuation multiples (e.g., 5–8× ARR for healthy SaaS, depending on growth and efficiency). Use the calculator to sanity-check your current ARR band and track how improving MRR or ACV moves you into a stronger valuation range. :contentReference[oaicite:3]{index=3}

What is Annual Recurring Revenue (ARR)?

Annual Recurring Revenue (ARR) is the annualized value of your predictable subscription revenue, excluding one-off setup, implementation, or service fees.

It converts recurring cash flows into a clean annual number that finance teams use for budgeting, SaaS valuation multiples, and tracking revenue retention.

ARR also connects directly to metrics like MRR, ACV, ARPU, LTV, and net dollar retention, making it a core input for growth planning and investor reporting.

Formula

For subscription businesses, the most common ARR formulations are:

- From Monthly Recurring Revenue (MRR):

- From customers and monthly ARPU:

- From customers and Annual Contract Value (ACV):

When you track changes over time, net new ARR is often decomposed as:

Example

Imagine a B2B SaaS company with 1,000 active customers and a monthly ARPU of $120.

MRR is 1,000 × 120 = $120,000, so for the current subscription base.

If the same 1,000 customers move to annual contracts with an ACV of \$2,400 each, ARR becomes , reflecting how pricing and packaging lift recurring revenue, CLTV, and ultimately enterprise value.

How to Use the ARR Calculator (Annual Recurring Revenue)

This calculator lets you convert core SaaS revenue inputs (MRR, customers × ARPU, or customers × ACV) into clear ARR and MRR outputs, plus a short summary of your current revenue band.

Choose the input mode
- At the top, select From MRR, Customers × ARPU (monthly), or Customers × ACV (annual) depending on which data you actually track.
Enter your primary inputs
- - For From MRR, type your current Monthly Recurring Revenue in the MRR field.
- For Customers × ARPU (monthly), enter total paying customers and their average monthly ARPU.
- For Customers × ACV (annual), enter total paying customers and their average annual contract value.
(Optional) Include net new components
- - If you toggle “Include net new components” on, fill in any extra fields that appear (new ARR, expansion, downgrades, churn) so the tool can estimate Net New ARR and Ending ARR using variants of:
Review the Results table
- Check Annual Recurring Revenue (ARR), Monthly Recurring Revenue (MRR), Net New ARR (annualized), Ending ARR (with net new), and ARR Growth vs Base to understand your current run rate and growth in one place.
Interpret the summary band and iterate
- Use the bottom summary line (e.g., “ARR: $1,800,000 — MRR: $150,000/mo ( $1–3M PMF )”) to see which ARR band you’re in, then tweak inputs (customers, ARPU, ACV) to model paths to the next ARR stage.
