A separate rate from new business
Expansion win rate measures how many upsell and cross-sell opportunities convert, tracked apart from new logo deals. Blending the two produces a company win rate that describes neither motion. Expansion deals start with a customer who already bought, a signed contract, and a working relationship, so they should convert at a different rate. When both numbers are averaged into one, a collapsing expansion motion can hide behind strong new business until new business slows.Calculate it the same way as any win rate. Closed won expansion opportunities divided by total resolved expansion opportunities in the period. Run it on count and on dollars, because the two answer different questions.
Why the number is usually wrong
Expansion opportunities rarely get the hygiene applied to new business. Three habits break the math:
- Losses are never logged. An upsell that stalls gets a new close date instead of a lost stage, so the denominator stays small. - Opportunities are opened speculatively. Account teams create expansion records to show coverage, not because a customer asked for anything. - Amounts are aspirational. The number in the CRM reflects the full package rather than what the customer will approve.
ORM's point is that most deals close for less than the value they carry in the CRM. The illustration Pete Furseth uses: a pipeline averaging $80,000 per deal against closed-won deals averaging $40,000. Expansion pipeline is more exposed to that gap than new business, because no procurement process forces the number to get real early.
The signals that predict the outcome
According to ORM, the best signal that a deal is slipping is a rep changing the close date, and a deal that slips from one quarter to the next is less likely to close even when it sits in commit. The earliest signal is the absence of any signal at all: no activity, no data changing, no notes. On an expansion deal that absence is easy to miss, because the account is still being serviced and looks healthy in every other system.
ORM also applies a 12-month rule to opportunity age for most customers, and counts meaningful activity as a change in stage, close date, or amount. Applying that rule to expansion pipeline removes the records that quietly inflate the win rate denominator or, worse, sit in the forecast.
Using it
Track expansion win rate by motion, since upsell and cross-sell convert differently, and by segment, since enterprise expansion runs on a slower clock than mid-market. Compare it against deal slippage on the same population. A stable win rate with rising slippage means the deals will still close, later. A falling win rate with stable slippage means the base has stopped buying, which is a product and adoption problem that no amount of pipeline will fix.
Frequently Asked Questions
How do you calculate expansion win rate?
Divide expansion opportunities closed won by all expansion opportunities that reached a resolution in the period, won plus lost, and exclude anything still open. Run the calculation on opportunity count for a conversion read and on dollars for a revenue read, because a high count rate with a low dollar rate means the big expansions are the ones failing.
Should expansion win rate be higher than new logo win rate?
Usually yes, because the customer has already bought once and the procurement path exists. If expansion win rate sits near the new logo rate, the pipeline is likely inflated with speculative opportunities that account teams opened to look active rather than opportunities a customer asked for.
Why is expansion win rate often overstated?
Because losses go unrecorded. An upsell conversation that fizzles frequently gets pushed instead of marked lost, so the denominator never grows and the rate stays artificially high. Enforcing the same stage and disqualification rules used on new business is what makes the number comparable.
What does a falling expansion win rate signal?
Most often a value problem in the installed base rather than a selling problem. When customers stop buying more, adoption has usually plateaued or the outcome they bought for has not landed. A falling expansion win rate tends to show up before contraction and churn.
