MRR Target Calculator

Reverse-engineer the MRR target needed to hit any ARR goal. See the monthly compound growth path.

Quick Answer

MRR Target = ARR Goal ÷ 12. Required monthly growth = (Target ÷ Current) ^ (1/months) - 1.

About This Tool

The MRR Target Calculator reverse-engineers the path from current MRR to any ARR goal. Most SaaS founders set ARR goals without doing the compound math to see whether the goal is realistic at the timeline. This tool plots the monthly milestones — and shows whether the required growth rate is in line with stage benchmarks or impossibly aggressive.

The Compound Growth Reality

Hitting $1M ARR from $25K MRR in 18 months requires roughly 6.9% monthly compound growth. Achievable for product-market-fit SaaS, but not trivial — sustaining 7% monthly growth means consistently shipping product, marketing, and sales improvements. Hitting $1M ARR from $10K in 12 months requires 19% monthly compound growth — possible only with strong product-led growth or aggressive enterprise deal closing. Most realistic 0-to-$1M ARR paths take 18-30 months.

Stage-Specific Growth Benchmarks

$0-$1M ARR: 10-20% monthly growth is typical and expected. Below 10% suggests product-market fit issues. $1-5M ARR: 5-10% monthly growth indicates strong execution. T2D3 (triple-triple-double-double-double) framework targets ~10% monthly through this stage. $5-10M ARR: 4-7% monthly. $10-50M ARR: 3-5% monthly. $50M+ ARR: 2-4% monthly. Compare your required growth rate to your current stage to assess realism.

Net New MRR vs. Total MRR

The headline target is total MRR, but the operating metric is net new MRR per month. Net New MRR = New MRR + Expansion MRR + Reactivation MRR - Contraction MRR - Churned MRR. To grow MRR by $5K, you might need to add $7K of new and expansion to overcome $2K of churn. Track each component separately. A company growing primarily through expansion (existing customer upgrades) has very different unit economics from one growing through new logos.

Capital Efficiency vs. Pure Growth

Hitting MRR targets through paid ads at unprofitable CAC inflates revenue but burns cash. The Rule of 40 (Growth Rate + EBITDA Margin ≥ 40%) keeps growth honest. A SaaS growing 100% YoY but burning 70% of revenue is at -20 on the Rule of 40 — bad. Same growth at 0% margin is at +100, excellent. Plan MRR targets alongside cash burn and runway, not in isolation.

Plan Quarterly, Not Monthly

Most monthly forecasts diverge within 60-90 days. Sales cycles, marketing campaign timing, and product launches all create lumpy MRR additions. Plan to monthly milestones but evaluate against quarterly targets. If you are behind plan at quarter-end, replan the next quarter with realistic numbers. Year-end ARR is what investors and board members measure, not month-by-month volatility.

Frequently Asked Questions

How do I calculate my MRR target?
MRR Target = ARR Goal ÷ 12. To hit $1M ARR, you need $83,333 MRR. To hit $5M ARR, $416,667 MRR. To hit $10M ARR, $833,333 MRR. The simple math obscures the work — getting from $25K MRR to $83K MRR requires sustained net new MRR every month after accounting for churn, expansion, and contraction.
What growth rate is needed to hit $1M ARR?
Depends on starting point and timeline. From $10K MRR to $83K MRR (1M ARR) in 18 months requires ~12.5% monthly compound growth. From $25K to $83K MRR in 18 months requires ~6.9% monthly. From $50K to $83K in 12 months requires only ~4.3% monthly. Most early-stage SaaS hits 10-20% monthly growth in the $0-1M ARR range. Growth-stage companies ($1-5M ARR) typically see 5-10% monthly. At scale, 2-5% is strong.
What is the T2D3 framework?
T2D3 (Triple Triple Double Double Double) is a venture-scale SaaS growth path popularized by Battery Ventures. After hitting product-market fit (~$1-2M ARR), companies aim to triple ARR for two consecutive years, then double for three years. T2D3 progression: $2M → $6M → $18M → $36M → $72M → $144M. Few companies actually hit this — but it sets the bar for venture-scale outcomes.
How do I plan monthly MRR milestones?
Calculate required compound monthly growth to hit your goal: (Target MRR / Current MRR) ^ (1/months) - 1. Then plot monthly milestones. If you need 7% monthly growth and start at $25K, your month 1 target is $26.75K, month 2 is $28.6K, month 6 is $37.5K. Set both monthly net new MRR targets and quarterly milestones. Adjust quarterly based on actual performance — most plans diverge from forecast within 90 days.
Should I plan for linear or compound MRR growth?
Compound is the realistic SaaS pattern. Linear growth (adding the same dollar amount each month) ignores how new customers compound atop existing ones. A SaaS at $25K MRR adding $5K net new MRR per month grows linearly at first, but as the base expands, that same $5K becomes a smaller percentage growth — declining to the 1-2% per month range by $200K MRR. Compound modeling reflects the reality that growth rate decelerates as base scales.
