OKR vs KPI: The Difference and How to Use Both

Most companies that say they have adopted OKRs simply renamed their metrics spreadsheet. They swapped "KPI" for "key result", kept the same numbers, carried on with the same monthly meetings, and started calling it goal-driven management.

The symptom is easy to spot. If your OKR for the quarter is "keep NPS above 70" or "track monthly revenue", you did not write an OKR. You wrote a KPI in new clothes. And the distinction is not semantic: it decides whether the quarter produces change or just reporting.

The two concepts coexist perfectly well, but they do opposite jobs. Worth sorting out which is which before setting up the next cycle.

OKR and KPI: the difference in one sentence

A KPI is a permanent indicator that measures the current state of the business; an OKR is a time-boxed commitment to change that state. The KPI answers "where do we stand?" and exists forever. The OKR answers "what are we changing this quarter?" and expires at the end of the cycle.

The metaphor that survives a meeting: the KPI is the thermometer, the OKR is the treatment plan. The thermometer stays in the drawer all year and you reach for it whenever you need it. The treatment has a beginning, an end and a specific target. No doctor stops measuring temperature because the treatment finished, and no treatment consists solely of measuring temperature.

The ten-second test

Take what you wrote and ask three questions. Does it have an expiry date? Does it declare a starting point and a finishing point? If the company does nothing differently, does the number move on its own?

If the sentence is...	Then it is...	Why
"90-day repeat purchase rate"	A KPI	Measures a state, no deadline or target
"Keep repeat purchase above 18%"	A KPI with an alert	That is monitoring, not change
"Take repeat purchase from 18% to 26% by December"	A key result	Has a baseline, a target and a deadline
"Make repeat purchase our growth engine"	An objective	Qualitative direction, no number

Notice that the same indicator, repeat purchase rate, appears in all four rows. That is why "is this a KPI or an OKR?" almost never has an answer if you only look at the metric. The answer lives in the phrasing.

OKR and KPI examples by department

The part that generates the most confusion is translating the theory for the team. One reference per area:

Area	KPIs you always track	One key result for the quarter
Marketing	CAC, CPL, traffic by channel, conversion rate	Cut CAC from $95 to $80 without reducing lead volume
Sales	Average order value, close rate, sales cycle	Shorten the average cycle from 42 to 30 days in the SMB segment
Finance	Margin, overdue receivables, days sales outstanding	Bring overdue receivables from 6.4% to 3.5% by cycle end
Support	Response time, CSAT, ticket volume	Resolve 70% of tickets on first contact (today: 48%)
Product	Churn, weekly usage, time to first value	Take 7-day activation from 31% to 50%

In a subscription business, the left-hand column is essentially the list of SaaS metrics the team already watches. Notice the asymmetry: the KPI column is long and stable, the key result column is short and changes every cycle. That is the correct shape. If a team's OKR list has twelve items, it turned into a report. Google's OKR guide recommends three to five objectives with around three key results each, precisely to avoid diffusion of effort.

How an OKR is scored

Here lies the most expensive misunderstanding. An OKR is not hit or missed; it is a score from 0 to 1, and the expectation is not 1. Google works with a healthy band between 0.6 and 0.7, on the logic that anyone who consistently reaches everything set comfortable targets.

An example with real numbers. Objective: "make repeat purchase our growth engine". Three key results and what happened during the quarter:

Key result	Baseline	Target	Landed at	Score
Repeat purchase rate	18%	26%	23%	0.63
Average LTV	$540	$700	$640	0.63
CAC	$95	$80	$86	0.60

Each score is progress across the promised range. Repeat purchase moved 5 points of the 8 required: 5 ÷ 8 = 0.63. CAC fell $9 of the $15 required: 9 ÷ 15 = 0.60. The objective's score is the average: 0.62.

None of the three targets was reached, and the quarter was a good one. This is the point that stalls adoption most often in organisations where the commercial quota culture taught everyone that 100% is the floor. Import that ruler into OKRs and the team will write targets it knows it can reach, and you will have spent three months discovering the obvious.

Five mistakes that kill OKRs in practice

1. Turning a KPI into a key result. "Keep uptime at 99.9%" is normal operations, not quarterly ambition. If the number is already where it should be, it is a health indicator, and its home is the dashboard.

2. Tying OKRs to bonuses. Google's guide states plainly that OKRs are not synonymous with employee evaluations. The reason is arithmetic: the minute the score becomes compensation, everyone starts writing easy targets, and the tool loses exactly the function that justified adopting it.

3. Writing key results with no baseline. "Increase repeat purchase" is not measurable. "From 18% to 26%" is. And to write the "from", somebody has to know today's number, which usually reveals that the company does not measure what it thinks it measures.

4. Reviewing only at quarter end. A 90-day cycle with a single check on day 90 is a 90-day cycle without management. The minimum cadence is weekly or fortnightly, which requires the numbers to be reachable without somebody assembling a spreadsheet first.

5. Assuming the team understood. This is the quietest one. Gallup research covering more than 75,000 US workers in 2023 found that fewer than half strongly agree they know what is expected of them at work, at 47% among fully remote and 41% among hybrid employees, below their 2020 levels. Writing the OKR in a document is not the same as the team knowing what to do on Monday.

When OKRs are not worth it

The limit is worth admitting. OKRs require three things: priorities that hold steady for at least a quarter, trustworthy numbers to measure progress, and someone who runs the cadence. Miss any one of them and the framework becomes ceremony.

A five-person company hunting for product-market fit changes priorities every three weeks; for them a quarterly cycle is a straitjacket. An operation that does not yet trust its own data will spend every meeting arguing about whether the number is right rather than what to do about it. In those cases the honest route is to start with the right KPIs for each funnel stage and a simple review routine, leaving OKRs for when there is something to prioritise.

The sequence that works is this: reliable indicators first, then the habit of looking at them, only then cycle objectives. It is the same order that separates a genuinely data-driven company from one that just repeats the phrase. Skipping a step is the most common reason the third attempt at OKRs gets abandoned like the first two.

Frequently asked questions

Are OKRs and KPIs the same thing?

No. A KPI is a permanent indicator showing the state of the business; an OKR is a deadlined commitment to change some state. They overlap because a key result almost always uses a KPI as its unit of measure, but each one does a different job.

Can a KPI become a key result?

Yes, and it is the most common case. Just add a baseline, a target and a deadline. "Conversion rate" is a KPI; "take conversion rate from 1.8% to 2.5% by December" is a key result. The indicator is identical, the commitment is what changed.

How many OKRs should a company have?

Few. Google's guide suggests three to five objectives per cycle, with around three key results each. Small teams usually work better with one or two objectives. A long list is almost always a sign that nobody actually prioritised.

What is the difference between an objective and a key result?

The objective is qualitative and says where to go ("make repeat purchase our growth engine"). The key result is numerical and says how you will know you arrived ("repeat purchase from 18% to 26%"). An objective with no number becomes rhetoric; a key result with no objective becomes a spreadsheet without a purpose.

Do OKRs work for small companies?

They do, as long as priorities last a quarter and there is a trustworthy number to measure progress. Below that, a short list of monthly targets delivers the same outcome with less process. The framework is not the goal; focus is.

What decides the outcome is not the framework

A well-written OKR and a well-chosen KPI solve different problems, and companies that keep them separate decide faster for a simple reason: at any moment they know which number is there to be watched and which one is being deliberately pushed. Confusing the two is what produces long meetings and quarters without change.

The bottleneck is almost always cadence. Reviewing a key result every week only happens when the numbers sit one question away rather than three exports and a spreadsheet. By connecting Meta Ads, Google Ads, GA4, CRMs and spreadsheets, Sherlok lets you ask in plain language "how is repeat purchase tracking against the quarterly target?" and get the answer ready, which turns the weekly review into a five-minute job. It is also worth revisiting what separates a dashboard from a report before designing how you will track the cycle.
