Running a subscription business means tracking a handful of numbers obsessively. MRR tells you how much recurring revenue you have right now. ARR annualizes that figure for board decks and investor conversations. LTV tells you the total value of a customer over their lifetime, while CAC tells you what it costs to win them. The ratio between the two is one of the most watched signals in SaaS.
NRR captures whether your existing revenue base is growing or shrinking without counting new sales. Gross margin shows how efficiently you deliver the product. And break-even analysis tells you exactly how many subscribers you need to cover fixed overhead. These eight tools cover all of it in one place.

MRR is your total recurring revenue collected each month from active subscriptions. ARR is simply MRR multiplied by 12. Companies use ARR in investor reports and forecasts because it presents the business on an annual scale. For operational decisions, MRR is usually more useful because it reflects what is happening right now.
The widely cited benchmark is 3:1 or better. An LTV of $1,500 against a CAC of $500 means you recover acquisition costs three times over during a customer's lifetime. Below 3:1 suggests you may be overspending on acquisition relative to the value each customer delivers. Above 5:1 can indicate you are underinvesting in growth.
Yes. The formulas used are standard SaaS accounting definitions. Enterprise deals often involve annual contracts and usage tiers, which can make some inputs like ARPU less straightforward. Use the contract value divided by 12 as your monthly equivalent, and the calculators will handle the rest correctly.
