A KPI (Key Performance Indicator) is a measurable value that tells you how well your business is performing against a specific goal. It's the metric you watch to know if you're on track or off track.
A business without KPIs is flying blind. You might feel like you're working hard, but you don't know if you're getting closer to your goal or further away. KPIs turn feelings and observations into numbers that guide decisions.
For investors and lenders, KPIs are proof that you understand your business and can manage it. They want to see you tracking the right metrics and hitting targets. A founder who can't articulate their top three KPIs and their month-to-month trend won't get funded.
For teams, KPIs create alignment. When everyone knows "we're targeting 40% gross margin and we're at 35%", the whole team can work toward that. Marketing knows it can't spend more to acquire customers. Operations knows it needs to cut costs. Without shared KPIs, teams pull in different directions.
For business owners, KPIs are the early warning system. When a KPI drops suddenly, something is broken. Maybe customer churn spiked (product issue) or CAC rose (market saturation) or days sales outstanding stretched (credit management issue). Good KPI tracking spots problems weeks before they become crises.
Effective KPI management follows a simple loop: Define, Measure, Track, Act, Adjust.
Step 1: Define
Choose 3 - 5 KPIs that matter most to your business. Too many KPIs dilute focus. For a startup, this might be: Monthly Recurring Revenue, Customer Acquisition Cost, and Cash Runway. For a consulting firm: Utilization Rate, Average Bill Rate, and Days Sales Outstanding. These are your decision drivers.
Step 2: Measure
Calculate the KPI the same way every period. Write down the formula. Use consistent data sources. If Customer Acquisition Cost requires marketing spend and new customer count, always use the same definitions (is a trial customer a "new customer"? Is a referral counted as acquisition?).
Step 3: Track
Record the KPI every week or month. Plot it on a simple chart. You're looking for trend: Is it moving toward your target or away? Seasonal businesses might see quarterly swings - know your pattern.
Step 4: Act
When a KPI drifts from target, investigate and adjust. If churn spiked, talk to customers leaving. If CAC rose, test different channels. If cash runway dropped below your threshold, cut costs or raise money. KPIs are actionable - if you can't do something about it, it's not a KPI, it's just trivia.
Step 5: Adjust
As your business scales, your KPIs change. A startup's KPI is cash runway; a profitable company's KPI is return on capital. A product launch requires focus on product engagement KPIs; a scaling phase requires focus on unit economics. Revisit your KPIs quarterly.
Real example:
A B2B SaaS business defines three KPIs: MRR (monthly recurring revenue), CAC (customer acquisition cost), and LTV (lifetime value). Month 1: MRR = £10k, CAC = £5k, LTV = £30k. LTV/CAC = 6, which is healthy (target is > 3). Month 2: MRR = £12k (good), but CAC rose to £7k (concerning). The team investigates: organic traffic dropped and they shifted to paid ads. They adjust by testing cheaper channels. Month 3: CAC drops back to £6k. KPIs are back on track.

A KPI is a number you track because it matters to your business. It could be revenue per month, customer acquisition cost, repeat customer rate, website conversion rate, or cash runway. A KPI is specific (not vague), measurable (you can calculate it), and tied to a goal (e.g., hit £100k revenue in month 6). Every business has different KPIs based on their model. A SaaS company watches monthly recurring revenue and churn. A consulting firm watches utilization and rate realization. A retail business watches inventory turns and margin.
Finance KPIs: Monthly Recurring Revenue (MRR), Customer Acquisition Cost (CAC), Lifetime Value (LTV), Gross Margin, Net Profit Margin, Cash Runway, Days Sales Outstanding (DSO). Operational KPIs: Customer Churn Rate, Employee Turnover, Project Completion Rate, On-Time Delivery Rate, Invoice Accuracy. Sales KPIs: Sales Pipeline Value, Conversion Rate, Average Deal Size, Sales Cycle Length. The right KPIs depend on your business model and strategy. Pick 3 - 5 that matter most and track them weekly or monthly.
A metric is any measurable number (website page views, emails sent, invoices created). A KPI is a specific metric that's tied to your business goal and success. All KPIs are metrics, but not all metrics are KPIs. Page views are a metric; conversion rate is a KPI (because it directly affects revenue). You might track dozens of metrics, but you should focus on 3 - 5 KPIs that predict success.
KPI formulas vary by type. Revenue = Units Sold × Price per Unit. Customer Acquisition Cost = Total Marketing Spend / New Customers Acquired. Gross Margin = (Revenue - Cost of Goods Sold) / Revenue × 100. Churn Rate = (Customers Lost / Customers at Start of Period) × 100. Days Sales Outstanding = (Accounts Receivable / Daily Revenue). Write down the formula for each KPI you track, calculate it the same way each month, and compare to your target.
Review weekly for fast-moving KPIs (daily revenue, cash burn, active projects). Review monthly for slower-moving KPIs (gross margin, churn, CAC). Review quarterly for strategic KPIs (market share, customer satisfaction). The frequency depends on how volatile the metric is and how quickly you can act on it. If a KPI moving 10% changes your decisions, track it weekly. If it only matters year-end, track it quarterly.
Yes. Aarvo calculates key financial KPIs automatically: gross margin, operating margin, cash runway, days sales outstanding, and burn rate. These appear on your dashboard updated daily from your bank feeds and invoices. You can set targets for each KPI and Aarvo alerts you if you fall off track. For non-financial KPIs (churn, CAC, conversion), you'll integrate other tools, but Aarvo is your financial KPI hub. Sign up at aarvo.com/signup to see your KPIs live.
Burn rate is how much cash your business spends each month relative to how much it earns. You calculate it by subtracting your monthly revenue from your monthly expenses. It's the speed at which you're running out of cash.
The total income your business earns from selling products or services, before any costs are deducted. It's the top line of your income statement and the starting point for calculating profit.
