MRR & ARR calculator
Enter customers, price, new signups and churn to get MRR, ARR, churned MRR and a growth projection. Free, USD or INR, no signup.
MRR = customers × revenue per customer. ARR = MRR × 12. The projection compounds new signups against churn each month over your horizon.
- ARR (MRR × 12)$144,000
- Net new MRR / month$1,440
- Churned MRR / month$360
- Projected MRR in 12 mo$26,696
- Projected ARR in 12 mo$320,347
Growing MRR is a follow-up game. Autocloz runs every channel and a free-forever CRM in one login — so more of your pipeline converts without another subscription per rep.

Recurring revenue begins as one multiplication: paying customers times what each pays per month. The annual figure is that total times twelve, which makes it a run rate — what the next year bills if absolutely nothing moves — rather than a forecast.
Churned revenue applies your monthly logo churn to the current total, and the net new line subtracts it from what your incoming signups add. Everything after those two comes from a loop instead of a formula: each pass strips the churned share off the customer base, adds the new customers you entered, and carries the survivors forward. The horizon is clamped between one and 120 months.
The ceiling hiding inside the projection
Because churn eats a percentage of a base that keeps growing while signups stay flat, the curve does not compound forever. It bends toward a ceiling, and that ceiling is just new customers per month divided by your monthly churn rate.
Fifteen signups against three percent monthly churn converges on five hundred customers, and stretching the horizon only inches closer to that figure. This one division is the most useful thing on the page: if the ceiling sits under the customer count your plan depends on, patience will not get you there and only two levers exist — win more per month, or lose fewer.
Read net new before you read the headline
Net new is the only figure here that can go negative, which makes it the one to watch month over month. When churn outweighs what fresh signups contribute, the big number at the top of the card still looks impressive while the business shrinks underneath it.
The gap between the two also names the problem for you. A small churn figure alongside a small net new points at the top of the funnel; a large churn figure swallowing a healthy signup number is a retention problem, and buying your way past that gets expensive quickly.
What this model deliberately leaves out
It tracks logo churn only — customers leaving, not accounts shrinking. There is no expansion revenue, no downgrade, no seat growth and no annual uplift, so a product with strong upsell will read pessimistically here and one with heavy contraction will read too kindly.
Price and signup volume are also held flat across every month of the horizon. That is deliberate: it isolates churn as the single moving variable so you can see its shape without three other assumptions drifting at once. The currency switch is cosmetic — it changes the symbol and the digit grouping, never the arithmetic.
MRR & ARR FAQ
How do you calculate MRR and ARR?
+
Monthly recurring revenue (MRR) = number of paying customers × average revenue per customer per month. Annual recurring revenue (ARR) = MRR × 12.
How does the growth projection work?
+
Each month the model adds your new customers and removes churned customers (current customers × monthly churn rate), then multiplies the resulting count by your average price to project future MRR and ARR over the horizon you set.
What is churned MRR?
+
The recurring revenue you lose each month from customers who cancel: current MRR × monthly churn rate. Net new MRR is new-customer MRR minus churned MRR.
Does it work in INR?
+
Yes — toggle between USD and INR for price and every revenue figure.
