How much do you spend to win a dollar of new ARR? For SaaS B2C and B2B2C startups, this magic number is your growth unlock - or your stall point.
Most SaaS companies waste their sales & marketing budgets chasing growth. The gap between go-to-market (GTM) spending and new revenue gives a deeper understanding to unlocking how you see both your inefficiencies and your opportunities.
What is Ratio of GTM Spend to New ARR?
Often termed the Magic Number and technically known as GTM Efficiency Ratio, or GTM Spend Ratio, the Ratio of GTM Spend to New ARR measures:
For every dollar spent (in Sales & Marketing), how many dollars of ARR do you earn?
Definition:
The Ratio of GTM Spend to New ARR measures the total sales and marketing expenditure required to generate one dollar of net new Annual Recurring Revenue (ARR)Formula:
GTM Efficiency Ratio = Total Sales & Marketing Spend ÷ Net New ARRKey Components:
Net New ARR: Includes revenue from new customers, expansions/upsells, and contractions/churn.
GTM Spend: Encompasses all S&M expenses (salaries, advertising, technology, etc.).
Example Calculation
A B2C SaaS startup spends $500,000 on S&M in a year.
It generates $200,000 in New ARR and $50,000 in Expansion ARR but loses $30,000 to churn.
Net New ARR = ($200,000 + $50,000) - $30,000 = $220,000.
GTM Efficiency Ratio = $500,000 ÷ $220,000 = 227%This implies the company spends $2.27 to acquire $1 of net new ARR, aligning with the median for public SaaS companies
Context: The median GTM Efficiency Ratio for public SaaS companies is 264% (Q3 2023)
What Okta Taught the SaaS World About GTM Spend (Don’t Repeat This!)
Context (FY 2023)
$1.1B spent on Sales & Marketing
Net New ARR of $495M (calculated from 22% YoY subscription growth on $2.25B ARR)
GTM Efficiency Ratio: $1.1B / $396M = 278% (spent $2.78 to earn $1 of ARR)
Result (FY 2023)
Revenue grew 65% YoY to $2.16B (FY2023), but GAAP (Generally Accepted Accounting Principles) operating margin worsened to -43.7% due to inefficient S&M spend
Stock price dropped 61% in fiscal 2023 amid investor concerns about bloated GTM costs
Lesson: Even with strong revenue growth, a GTM Efficiency Ratio >250% signals unsustainable burn.
Why It Matters
Investor Magnet: A healthy ratio signals you know how to turn dollars into durable revenue -that is critical for funding and valuation.
Survival Signal: Ratios above 200-250% for too long indicate excessive cash burn, growth stalls, and board concerns.
Clarity for Pivots: Pinpoint where your GTM model leaks spend to enable fast, strategic pivots.
For B2C and B2B2C startups, this ratio is particularly critical due to their reliance on high-volume, low-touch acquisition models and product-led growth strategies.
Factors that lead to Common Calculation Errors
Hidden Costs: Startups often forget to include salaries, overhead, and tech costs in their S&M calculations.
Net New ARR: Revenue numbers are often inflated by not subtracting customer churn and contract reductions.
Customer Mix: Companies incorrectly combine acquisition costs across different segments - enterprise and B2C customers have distinct CAC profiles.
Timing Gaps: Marketing spend from one quarter is wrongly matched with ARR from another, ignoring the actual sales cycle length.
Organic Growth: Revenue from unpaid channels like referrals gets counted while S&M costs remain unadjusted.
For B2C startups, the combination of high customer volume and low average contract values creates multiplier effect on mistakes.
The Efficiency Cliff: Where B2B and B2B2C Startups Scale or Sink
Growth Stage | B2C Target Ratio | Strategic Fixes |
Validation Seekers ($1M-$2M ARR) | 100–150% | Viral loops Paid channel testing Avoid over hiring |
Traction Builders ($2M-$4M ARR) | 120–170% | Double down on best CAC channels Optimize funnel |
Scale Preparers ($4M-$7M ARR) | 110–160% | Automate onboarding Reduce churn Upsell in-app |
Growth Accelerators ($7M-$10M ARR) | 100–150% | Reduce paid spend Boost LTV Focus on retention |
Growth Stage | B2B2C Target Ratio | Strategic Fixes |
Validation Seekers ($1M-$2M ARR) | 150–200% | Founder-led sales Early partner pilots PLG tests |
Traction Builders ($2M-$4M ARR) | 180–240% | Refine partner onboarding Automate lead generation |
Scale Preparers ($4M-$7M ARR) | 170–220% | Expansion revenue In-product upsell GTM automation |
Growth Accelerators ($7M-$10M ARR) | 150–180% | Hybrid GTM (PLG + sales) Optimize partner expansion |
What happens if you miss the mark?
B2C: Ratios >170% → Cash burn, unsustainable growth.
B2B2C: Ratios >220% at $7M+ ARR → Partner friction, stalled growth
The path to $10M+ ARR isn't about spending more-it's about spending smarter. Master the ratio, or risk becoming a cost-heavy cautionary tale.
How to Move Your Metrics
1. Build Around Product-Led Growth: Let your product sell itself. When people can sign up and start using your product without talking to anyone, good things happen. Product-led growth (PLG) can reduce CAC by 25-40%, as seen in HubSpot’s 2023 PLG adoption study.
2. Optimize Your Funnel: Use analytics to spot friction points. Kill underperforming channels and double down on those with the best CAC-to-ARR ratios. Small tweaks can yield big efficiency gains.
3. Automate Outreach and Onboarding: Set up smart systems for reaching out to leads and getting them started. Good automation doesn't just save time - it helps you grow without burning cash. Use AI to score leads and automate follow-ups. Your sales cycles will shrink.
4.Sell More to Happy Customers: The easiest sale? To someone who already loves your product. Make it simple for current customers to buy more. Expansion ARR is 5-7x cheaper than new customer acquisition, per ProfitWell’s 2024 SaaS Metrics Report.
5. Check Your Spending Quarterly: Review all sales and marketing expenses every quarter. Cut or renegotiate tools, agencies, and dead-end campaigns that aren’t moving the needle. Aim for 15-25% savings and reinvest in proven winners.
Key Takeaways
GTM Spend to New ARR Ratio is your efficiency pulse: Track it monthly and segment by acquisition vs. expansion.
PLG and automation are your best friends: They drive down CAC and scale revenue without bloating costs.
Expansion ARR is gold: Focus on growing existing accounts for the highest ROI.
Regular audits keep you lean: Don’t let waste creep into your GTM engine.
Efficiency today = resilience and valuation tomorrow: The tighter your GTM spend, the faster and stronger you grow.
