How to Choose the Right KPIs (Leading vs Lagging Indicators)
How to choose the right KPIs for your business: a five-step method, leading vs lagging indicators explained, examples by goal and a worked rand example.

To choose the right KPIs, start from a goal, pick one lagging indicator that proves you reached it, then pick two or three leading indicators you can influence this week that predict it. Keep the total small, give each an owner and a target, and drop any KPI that never changes a decision. This guide walks through the method with examples.
Leading vs lagging indicators
A lagging indicator measures an outcome after it has happened: revenue, profit, churn, customer satisfaction. It is easy to measure and hard to argue with, but by the time it moves it is too late to change. A leading indicator measures an activity or condition that tends to come before the outcome: pipeline created, website trial sign-ups, on-time delivery, debtor days. It gives you time to act, but the link to the outcome has to be tested.
| Goal | Lagging indicator | Leading indicators |
|---|---|---|
| Grow sales | Monthly revenue | Qualified pipeline added, win rate, proposals sent |
| Keep customers | Churn or repeat rate | Product usage, support tickets per customer, CSAT |
| Improve cash | Cash in bank, runway | Debtor days, overdue invoices, stock days |
| Deliver reliably | Customer complaints | OTIF, first-pass yield, WIP |
| Grow an online store | Monthly profit | Sessions, conversion rate, AOV, CAC |
A five-step method for choosing KPIs
- Write down two to four goals for the next 6–12 months. Specific ones: ‘grow repeat revenue’, not ‘be customer-centric’.
- Pick one lagging indicator per goal that would prove you achieved it, with a target and date.
- Map the drivers. Ask ‘what has to happen for that number to move?’ and write the chain down. Revenue = leads × conversion × deal size, for example.
- Choose two or three leading indicators from the chain that you can measure at least weekly and that someone can directly influence.
- Assign an owner, a target and a review rhythm, then check after three months whether the leading indicators actually predicted the lagging one.
Worked example: a cleaning services company
Say your cleaning business turns over R450,000 a month from about 150 contract clients averaging R3,000 each. The goal is to reach R540,000 a month within a year. The lagging indicator is monthly contract revenue, target R540,000.
Mapping the drivers: revenue = active clients × average contract value. To get there you could add 30 clients at R3,000, or add 15 clients and lift average value to R3,270. But you also lose clients: if 3 cancel each month (2% monthly churn), you lose 36 a year and need to win about 66 just to net 30. That shows churn matters as much as sales.
- Leading indicator 1: quotes sent per week (target 8, with a historical quote-to-win rate of about 15%, giving roughly 1.2 wins a week or 60 a year).
- Leading indicator 2: client complaints per 100 cleans (cancellations usually follow complaints, so this predicts churn).
- Leading indicator 3: upsell proposals to existing clients per month (drives average contract value).
Each has an owner (sales, operations manager, account manager), each is measurable weekly, and together they explain most of the movement in revenue. Four KPIs replace a spreadsheet of 30 numbers nobody reads.
Once you know your KPIs, Summarix can calculate them from your data every week and send a short report with the trends explained.

What makes a good KPI
- Tied to a goal. If you cannot say which goal it serves, it is a metric, not a KPI.
- Controllable. Someone can take action this week that moves it.
- Clearly defined. Written formula, data source and time period, so it is calculated the same way every month.
- Timely. Available often enough to act on. A KPI you get once a quarter can only be lagging.
- Hard to game. Pair speed with quality (response time with CSAT, throughput with first-pass yield) so improving one cannot hide damage to the other.
Common mistakes
- Too many KPIs. Five to ten for the business and three to five per team is plenty.
- Only lagging indicators. You find out about problems when it is too late.
- Vanity metrics. Social followers or page views that do not connect to revenue or retention.
- Targets without context. Always show the trend and a comparison period, not just a single number.
Putting your KPIs to work
If you need a starting list, 15 KPIs every small business should track covers the basics. A consistent monthly business report template keeps the review on track, and data storytelling for business reports helps you explain what the numbers mean. Summarix can compute your chosen KPIs from spreadsheets or connected databases and send them on a schedule, with the figures calculated by code rather than guessed by AI.
Conclusion
The right KPIs are few, tied to goals and a mix of leading and lagging. Start from the outcome, map what drives it, choose a handful of leading indicators someone can act on, and test whether they really predict results. Revisit the list every quarter, and cut anything that is not changing decisions.
Frequently asked questions
What is the difference between leading and lagging indicators?
Lagging indicators measure outcomes that have already happened, such as revenue or churn. Leading indicators measure activities or conditions that tend to predict those outcomes, such as pipeline created or complaints.
How many KPIs should a business have?
Around five to ten at company level and three to five per team is a practical range. Fewer, well-chosen KPIs get more attention than a long list.
What are examples of leading indicators?
Qualified pipeline added, quotes sent, website trial sign-ups, debtor days, on-time delivery and customer complaints are common leading indicators for sales, cash and retention.
What makes a good KPI?
A good KPI is tied to a goal, clearly defined, measured often enough to act on, controllable by someone and hard to game.
