Series A Readiness Calculator
Series A readiness check.
Score Series A fundraising readiness across ARR, growth rate, net revenue retention, runway, and customer concentration metrics.
What this tool does
This tool calculates a readiness score based on five key metrics commonly reviewed during Series A fundraising discussions. It combines your annual recurring revenue, month-over-month growth rate, net revenue retention, available runway in months, and customer count into a weighted composite score out of 100. The score illustrates how your startup's current financial position and growth trajectory align with typical Series A expectations. Monthly growth rate and ARR typically carry the most influence on the outcome. For example, a company with strong ARR and rapid growth but limited runway will score differently than one with slower growth but extended cash runway. The calculator does not account for market conditions, product-market fit assessment, team composition, or investor sentiment—it focuses on quantifiable financial metrics only. Results are for educational comparison and illustrative purposes.

Series A readiness scored across five dimensions: ARR scale (target 1M+), month-over-month growth (8-15%+), net revenue retention (100%+), runway (12+ months), and customer count (50+). Score above 70 signals Series A readiness; below 40 means more building needed. Each VC weighs these differently but these five cover the fundamentals.
800k ARR, 10% MoM growth, 110% NRR, 15 months runway, 40 customers = ~72/100. Borderline ready. Strongest signal: growth + retention together. Weakest: customer count below 50 - some VCs want 100+ for pattern confidence. This is a self-assessment, not a fundraising guarantee - VCs also evaluate team, market, and product quality.
Series A benchmarks evolve with market conditions. 2021 peak: 500k ARR could raise Series A. 2024-2025: 1-2M ARR is standard floor. Growth rate expectations always high: 10%+ MoM or 2-3x year-over-year at minimum. Retention above 100% NRR is the strongest quality signal - proves product-market fit more than any other metric.
Quick example
With arr of 800,000 and mom growth of 10% (plus nrr of 110% and months runway of 15 months), the result is 68 / 100. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter ARR, MoM Growth %, NRR %, Months Runway, and Customers. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
What's happening under the hood
ARR (0-25), Growth (0-25), NRR (0-25), Runway (0-15), Customers (0-10). Weighted composite. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
What to do with a low result
A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
££800,000 ARR, 10% MoM, 110% NRR, 15mo runway, 40 customers = 68 / 100.

Sources & Methodology
Methodology
This calculator computes a readiness score by evaluating five key metrics commonly examined by investors in early-stage funding rounds. Annual recurring revenue receives a score from 0 to 25 points based on absolute value. Month-over-month growth rate is scored 0 to 25, reflecting the trajectory of revenue expansion. Net retention rate is scored 0 to 25, indicating customer value and expansion within the existing base. Months of runway receives 0 to 15 points, measuring financial sustainability. Customer count is scored 0 to 10 points. The final readiness score is the sum of these five component scores. The model assumes linear or stepwise scoring bands for each input and treats each metric as independent. It does not account for industry variation, market conditions, capital efficiency, customer concentration, burn rate composition, or the relative weighting different investors may apply to these factors.
