MRR (Monthly Recurring Revenue) is the predictable monthly income from subscription clients. For SaaS, service businesses, and retainer-based freelancers, MRR growth is the key metric. This calculator shows current MRR, annual recurring revenue, and projects year-end based on churn and new client acquisition.
20 clients at 200 monthly = 4,000 MRR, 48,000 ARR. With 5% monthly churn (1 client lost monthly) and 2 new clients monthly, annual net is +12 clients, ending at 32 clients and 6,400 MRR - 60% growth over the year.
Churn and new client rates matter more than people realise. Same starting MRR with 10% churn (2 lost monthly) vs 2 new = net zero growth. Small changes in either rate compound into large MRR differences over time.
Quick example
With current client count of 20 and average monthly fee of 200 (plus monthly churn rate of 5% and new clients per month of 2), the result is 4,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Current Client Count, Average Monthly Fee, Monthly Churn Rate, and New Clients per Month. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
Current MRR = clients × fee. ARR = MRR × 12. Annual churn = clients × churn × 12. Net new = new clients × 12 - churn. Year-end MRR = (clients + net new) × fee. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Re-running after each rate change
Freelance rates aren't set once. After any rate change, re-run this — the monthly and annual totals drift faster than people expect, and your runway number changes with them.
What this doesn't capture
Freelance income is lumpy. The calculation assumes steady work; reality includes dry spells, delayed invoices, and client churn. Plan against a pessimistic version of the result, not the central case.
20 × £200 £/mo with 5% churn + 2/mo new = $4,000.00 MRR.
