Average Deal Size Calculator: Formula and Median
Average deal size is the revenue from won deals divided by the number of won deals. Paste each won deal with its amount to see the average, the median, the smallest and largest deal and the average without the largest, or enter totals. Add a revenue target to see how many deals you need. Free.
Write one won deal per line: a name and the amount, for example “Acme, 12,000”. If you only know the totals, switch to the second option. Results update as you type, and the figures stay in this browser until you start over.
Average deal size example
A team won eight deals worth $120,000 in a quarter. Seven were between $7,000 and $15,000; one, Harbor Co, was $47,000. The target for next quarter is $250,000.
| Measure | Result |
|---|---|
| Average: $120,000 ÷ 8 | $15,000 |
| Median deal | $10,750 |
| Without Harbor Co | $10,428.57 |
| Won deals for $250,000 | 17 |
The average is well above the median because one large deal pulls it up. Planning with $15,000 a deal, the team needs 17 won deals; if Harbor Co was a one-off, it should plan with about $10,750 and expect to need more deals.
Average deal size formulas
- Average deal size: revenue from won deals ÷ number of won deals.
- Median deal: the middle deal when all won deals are sorted by amount.
- Deals needed: revenue target ÷ average deal size, rounded up.
Use deal size with other sales metrics
Average deal size is one of the four inputs of the sales velocity calculator. Turn the deals you need into opportunities with the win rate calculator, and see how long they take to close with the sales cycle length calculator.
Frequently asked questions
How do you calculate average deal size?
Divide the revenue from won deals in a period by the number of won deals. Eight deals that brought in $120,000 have an average deal size of $120,000 ÷ 8 = $15,000. Count only closed-won deals and use the same period, such as a quarter, every time.
Why look at the median deal as well?
One unusually large deal can lift the average far above what most customers pay. The median is the middle deal, so it shows a typical deal. If the average is well above the median, plan with the median or with the average without the largest deal.
How many deals do I need to hit my target?
Divide the revenue target by your average deal size and round up. At $15,000 a deal, $250,000 needs 17 won deals. To turn that into opportunities, divide by your win rate: at 25%, that is 68 opportunities.
Should I use contract value or first-year value?
Either works if you are consistent. For subscriptions, many teams use annual contract value so that one-year and three-year deals can be compared; others use total contract value. Note which one you used next to the result.
How can I increase average deal size?
Sell to the right-sized customers, offer packages or annual plans, add relevant upsells at the proposal stage and avoid discounting by default. Check the effect on win rate too: bigger deals that you win less often may not add revenue.
Is what I enter stored or sent anywhere?
