Monthly recurring revenue (MRR) growth forecast calculator

Try Calculator

Monthly recurring revenue (MRR) is an incredibly useful metric to keep track of, especially for software-as-a-service (SaaS) businesses with subscription-based business models. 

It refers to the revenue, or income, a business can predictably rely upon, on a monthly basis, taking into account the number of customers, how much they’re paying monthly, and how many you expect to lose.

In most cases, MRR relies on average revenue (and average churn) remaining constant. It’s not an infallible metric.

But tracking MRR, and more specifically how much it’s increasing, allows founders and financial decision-makers to make more accurate predictions about future revenue – and to make well-informed strategic decisions based on that.

MRR is similar in some ways to annual recurring revenue (ARR) but provides a more short-term outlook, which is often more relevant to young and fast-moving SaaS businesses.

Calculating MRR can also give some insight into how many new customers are required to reach your growth goals, and where investment in things like marketing or new hires could supercharge that growth in the short term. 

How is MRR calculated?

On the surface, an MRR calculation is relatively simple: multiply the number of monthly subscribers by the monthly subscription price, per subscriber.

If there are two tiers of pricing, regular and pro subscriptions, for example, do the calculation for the number of subscribers for each price point, then add them together.

However, calculations should also take into account customer churn – that is, people cancelling or downgrading subscriptions – as well as new customers, and those who upgrade, either permanently or temporarily.

Example:

Imagine a hypothetical B2B SaaS company offering a collaborative design tool with a freemium business model. There’s a free version, a paid ‘pro’ version, and a more expensive ‘deluxe’ version available.

The business has 1,000 customers using the free version.

Another 2,500 customers are paying for the ‘pro’ subscription, at $30 per month, generating monthly revenue of $75,000.

A further 1,000 customers pay for the ‘deluxe’ software, at $45 per month. This generates monthly revenue of $45,000.

Monthly recurring revenue is: $75,000 x $45,000 = $120,000

However, on average, the startup loses 150 ‘pro’ customers per month ($4,500), and 100 ‘deluxe’ customers ($4,500).

Each month, on average, 200 customers downgrade from ‘deluxe’ to ‘pro’, representing a loss of $15 per customer ($3,000).

So, average churned revenue is: $4,500 + $4,500 + $3,000 = $12,000.

Typically, however, 180 new customers join the ‘pro’ plan per month ($5,400), another 150 join the ‘deluxe’ plan ($6,750), and 200 upgrade from ‘pro’ to ‘deluxe’ ($3,000).

That equals an average monthly revenue increase of $14,250.

Net monthly revenue increase is: $14,250 - $12,000 = $2,250.

MRR: $120,000 + $2,250 = $122,250

This represents a little below a 2% increase in recurring revenue, month-on-month.

To assess MRR growth over time, calculate monthly net revenue, plus 2%, for each consecutive month.

How Tractor can help

Monthly Recurring Revenue is a key metric the Tractor Ventures team takes into account when making lending decisions. We have a base requirement of $50,000 in predictable, monthly revenue.

As a guide, Tractor can provide non-dilutive loans up to three times your MRR, based on your business’ needs, and what you plan to use the funding for.

Loans are intended to allow for investment in things like new equipment, key hires, marketing campaigns or even boosting stock reserves – any strategic spending that can help your company grow (and increase MRR) more quickly.

Loans are repaid over a set period, at a set cost, and as a set percentage of revenue generated.

As long as revenue keeps tracking up, founders can also refinance through Tractor as they grow, as many times as they want.

In fact, we’ve funded more than 170 Australian and NZ companies so far, and about a third of those companies have done exactly that.
