MRR Projection Tool

Monthly Recurring Revenue is the lifeblood of every subscription-based business. It represents the predictable revenue your company generates each month from active subscriptions, and it is the single most important metric investors, founders, and operators track when evaluating SaaS health and trajectory.

Projecting MRR forward is essential for financial planning, fundraising, and strategic decision-making. A 10% month-over-month growth rate might sound modest, but compounding turns it into a powerful force. At that rate, MRR more than triples in 12 months and grows over 30 times in 36 months. Understanding how your growth rate translates into future revenue helps you set realistic targets, plan hiring, and time fundraising rounds.

The projection uses compound growth, which means each month's revenue is calculated by applying the growth rate to the previous month's MRR, not just the starting figure. This mirrors how SaaS businesses actually grow: new customers add to the existing base, and revenue compounds on itself. The total revenue over the projection period sums up every individual month, giving you the cumulative cash your business will generate.

Keep in mind that real-world MRR growth is rarely perfectly smooth. Churn, seasonality, pricing changes, and sales cycles all create fluctuations. This tool gives you a clean baseline projection that you can use as a benchmark, and you should model conservative, moderate, and aggressive scenarios by adjusting the growth rate.

This calculator takes your current MRR, applies a monthly compound growth rate over your chosen time horizon, and returns the projected MRR at the end of the period, the total cumulative revenue generated, and the absolute dollar growth in MRR.
