Verdict
Your team cannot cover everything
The workload exceeds the capacity of the current headcount. In practice, accounts are not visited at the planned frequency, prospects come after customers, or reps cut corners on preparation. Hire, or lighten the load with the levers below.
- Exact figure: 4.71 reps. You cannot hire a fraction of a person: you need 5 full-time, or the equivalent in part-time.
- The current headcount is 1 rep short.
- At current headcount, 121 accounts are not covered at the planned frequency.
Your team against the need
One figure per full-time rep.
Workload build-up method, the classic sizing approach. The 85% and 100% thresholds are reading marks, not standards.
Workload, segment by segment
Contact hours per year, against the current team’s capacity.
| Segment | Accounts | Contacts / yr | Hours / yr | Share |
|---|---|---|---|---|
| Key accounts (A) | 40 | 480 | 1,200 | 25% |
| Mid-size accounts (B) | 120 | 720 | 1,620 | 34% |
| Small accounts (C) | 300 | 600 | 1,050 | 22% |
| Prospects to work | 150 | 450 | 900 | 19% |
| Total | 610 | 2,250 | 4,770 | 100% |
What you cover with 4 reps
Segments are served in priority order, whole accounts only.
121 accounts are not covered at the planned frequency.
Holding with the current headcount
One lever at a time, all else equal, to bring the load back to 100% of capacity.
| Lever | Change | Load after | Needed |
|---|---|---|---|
| Lower the frequency on “Prospects to work” | Go from 3 to 0.5 contacts a year (one contact every 24 months) | 99%Enough | 4 |
| Move “Prospects to work” to the phone | Remove 1 h of travel per contact | 107%Even at 0 h of travel, still 0.3 rep short | 5 |
| Shorten every contact | Shorten every contact by 28%, for example 1 h 15 → 54 min | 99%Enough | 4 |
| Raise the share of time in contact | Go from 55% to 65% of time in contact | 100%Enough | 4 |
This lever alone is not enough, even pushed to the maximum.
The calculation in detail
Your numbers, in the formulas.
- Workload = Σ accounts × contacts per year × hours per contact. For example Key accounts (A) : 40 × 12 × 2.5 h = 1,200 h. Total: 4,770 h a year.
- Useful capacity = 46 weeks × 5 days × 8 h × 55% = 1,012 h a year per rep.
- Reps needed = workload ÷ useful capacity = 4,770 h ÷ 1,012 h = 4.71.
- Team load = workload ÷ (headcount × useful capacity) = 4,770 h ÷ (4 × 1,012 h) = 118%.

For inside sales, contact length depends on your phone system. Dialing, waiting, hitting voicemail, taking notes: that time counts in the workload. Skipcall chains calls with a power dialer, dials up to four numbers in parallel and syncs your CRM: more contacts in the same hour, so fewer reps for the same portfolio.

Sales force sizing: three methods, one you can actually compute
There are three classic ways to set the size of a sales force. The historical, or ratio, method starts from revenue: divide the target by the average revenue per rep, or apply a sales payroll percentage to the revenue goal. Simple, but circular: it assumes past productivity repeats itself and says nothing about what each rep should do with their weeks.
The market potential method reasons by territory: estimate the number of potential customers and the reachable revenue in each area, then assign reps in proportion. Useful for carving territories, less so for deciding a total headcount, because it rests on market estimates that are hard to verify.
The workload method, also called the build-up method, is the only one that starts from what actually has to be done. List the accounts to serve, set a contact frequency and a contact length for each, and you get hours per year. Then measure the time a rep can really spend in customer contact, and divide. That is the method behind this calculator, because every assumption can be debated, measured and corrected.
The formula, with the starting example
Workload is computed segment by segment: number of accounts × contacts per year per account × length of a contact. In field sales, the length includes preparation, the meeting itself, follow-up notes and the round trip. With the starting assumptions, 40 key accounts seen 12 times a year for 2.5 hours including travel make 1,200 hours; 120 mid-size accounts seen 6 times for 2.25 hours make 1,620; 300 small accounts seen twice for 1.75 hours make 1,050; and 150 prospects worked 3 times for 2 hours make 900. That is 4,770 contact hours a year.
A rep’s capacity is not their presence time. Over 46 weeks of 5 days of 8 hours, a rep is present 1,840 hours. If 55% of that goes to customer and prospect contact, the rest going to admin, meetings, training and CRM, their useful capacity is 1,012 hours a year.
Reps needed is the ratio of the two: 4,770 ÷ 1,012 = 4.71. Since you cannot hire 0.71 of a person, you need 5 full-time, or 4 plus a well-calibrated part-timer. With 4 reps in place, the team load is 118%: the team cannot hold the planned frequency across the portfolio, and small accounts and prospects are usually the ones that suffer.
Reading the team load: marks, not standards
Team load divides the total workload by the capacity of the current team. Above 100%, the load does not fit: either the real frequency is lower than the one you think you apply, or reps cut corners on preparation and follow-up. Between 85% and 100%, the team is sized to the limit and absorbs neither a long absence nor portfolio growth. Below 85%, there is capacity left to prospect more or raise the frequency.
Those two thresholds are reading marks chosen for this tool, not market averages or standards. What matters is the consistency between your assumptions and measured reality: if the share of time in contact is actually 40% rather than 55%, the same team moves from “headroom” to “overloaded” without a single account changing.
The other way round: what your team can cover
Deciding on a headcount rarely happens overnight. In the meantime, the useful question is: with the reps in place, which accounts do we cover at the right frequency, and which do we leave aside? The calculator answers by serving segments in the order you ranked them, the first being the highest priority, whole accounts only, until capacity runs out.
The “with N reps” slider lets you test a hire, a departure or a move to part-time before it happens. It also shows the capacity left once the whole portfolio is covered: that is the extra prospecting volume the team could absorb.
How to fill in each assumption
The method is only as good as its inputs. Three of them deserve a real measurement rather than a guess.
- 1
Segment the portfolio
Group accounts that deserve the same contact frequency: key accounts, mid-size, small accounts, prospects. Three to five segments are enough. Rank them by priority; that order drives coverage.
- 2
Set a frequency and a length per segment
How many contacts a year does an account in this segment need to be well served? How long does a contact last, prep and notes included? In the field, add the average round trip. Start from the frequency you want, not the one you endure.
- 3
Measure real capacity
Count the weeks actually worked (vacation, public holidays, offsites), then the share of time spent in customer and prospect contact. A week of calendar reviewed line by line, or an activity log, gives a more reliable figure than a feeling.
- 4
Describe the team
The current full-time headcount on this portfolio. If you are hiring, tick ramp-up and enter the productivity expected in year one: a new hire does not cover a full portfolio on day one.
The levers before hiring
Hiring is not the only answer to an overload. The calculator prices four levers, one at a time; combine them if one is not enough.
-
Rethink the frequency of the last segment
Small accounts and cold prospects are often served out of habit. Lowering their frequency frees hours without touching the accounts that drive revenue.
-
Shorten contacts
Standardized prep, notes dictated in the car or typed during the call, tightly framed meetings: the average length drops by a few minutes, and a few minutes times thousands of contacts make hundreds of hours.
-
Raise the share of time in contact
Internal meetings, manual reporting, number lookup, CRM entry: everything that is not a customer contact can be reduced, automated or delegated. Every percentage point gained is worth close to twenty hours per rep per year, on 1,840 hours of presence.
-
Move a segment to the phone
In the field, small accounts can be served remotely, with no travel. The same number of contacts then costs far fewer hours, half as many with the starting assumptions, and frequency can even go up.
The mistakes that skew the sizing
-
Counting 100% of time as contact time
Nobody spends 1,840 hours a year in meetings. Forgetting admin, meetings and training understates the headcount by a third or more.
-
Forgetting travel
In the field, travel often weighs as much as the meeting itself. Setting it to zero amounts to assuming every customer is on the same street.
-
Ignoring ramp-up and turnover
A new hire produces little in the first months, and a departure leaves a portfolio unattended for weeks. Sizing to the limit means sizing for the ideal year that never comes.
-
Sizing on past revenue
Dividing the target by the average revenue per rep assumes productivity repeats whatever the accounts. Workload tells you what each rep has to do with their weeks.
-
Confusing desired and endured frequency
If you enter the frequency the team manages to hold today, the calculation will validate the current headcount by construction. Enter the frequency that keeps and grows the account.
