Quick answer: Most service businesses spend $8,000–$15,000/month on operations when you count tools, admin time, and revenue leakage from dropped leads and late payments. A managed operations platform costs $97–$497/month all-in. The gap is profit. This calculator walks you through the real math in five minutes.
You know you spend money on operations. Software subscriptions. Maybe a VA. Your own time.
But what’s the real number? Not just the invoices. The fully loaded cost.
This calculator helps you figure that out. Subscription costs. Admin hours. Revenue leakage from dropped leads and late payments. The hidden tax of broken operations.
The calculator
Step 1: Tool costs (monthly)
Add up every subscription you use for operations:
| Tool | Monthly Cost |
|---|---|
| Scheduling (Calendly, etc.) | $___ |
| CRM/Client management | $___ |
| Invoicing/Payments | $___ |
| Email marketing | $___ |
| Automation (Zapier, Make) | $___ |
| Project management | $___ |
| Communication (Slack, etc.) | $___ |
| Other | $___ |
| Total tools | $___ |
Benchmark: Most service businesses spend $150-500/month on tools alone.
Step 2: Admin time (monthly)
How many hours per week do you spend on:
- Responding to leads
- Scheduling calls/sessions
- Onboarding new clients
- Sending invoices and chasing payments
- Following up with past clients
- General admin (email, spreadsheets, etc.)
Hours/week: ___ × 4.3 weeks/month = ___ hours/month
Your hourly rate: $___ (use your billing rate or $150-300 if unsure)
Admin time cost: ___ hours × $___ = $___/month
Benchmark: Most founders spend 15-25 hours/week on admin. At $200/hour, that’s $12,900-21,500/month.
Step 3: Revenue leakage (monthly)
Leads going cold:
- How many leads/month do you get? ___
- What % go cold (no response, no booking)? ___%
- Average client value: $___
- Lost revenue: ___ leads × % × $ = $___/month
Late/unpaid invoices:
- Monthly invoiced revenue: $___
- % paid late (7+ days): ___%
- % never paid: ___%
- Lost revenue: $___ × (___% + %) = $/month
Client churn (early departures):
- Clients lost per month: ___
- Average package value: $___
- % that leave early (before full package): ___%
- Lost revenue: ___ × $___ × % = $/month
Total revenue leakage: $___ + $___ + $___ = $___/month
Benchmark: Most businesses lose 10-20% of potential revenue to leakage.
Step 4: The total
| Cost Component | Monthly Cost |
|---|---|
| Tools (Step 1) | $___ |
| Admin time (Step 2) | $___ |
| Revenue leakage (Step 3) | $___ |
| Total operations cost | $___ |
As % of revenue: Total ops cost ÷ Monthly revenue × 100 = ___%
Benchmark: Healthy service businesses run 10-15% of revenue on ops. Broken ops run 25-40%.
Example calculation
Let’s run the numbers for a typical coach/consultant:
Profile:
- 15 active clients
- $5,000/month revenue
- Solo founder (no staff)
Tool costs:
- Calendly: $16
- HoneyBook: $59
- Mailchimp: $20
- FreshBooks: $30
- Google Workspace: $12
- Total: $137/month
Admin time:
- 20 hours/week on admin
- 86 hours/month × $200/hour
- Total: $17,200/month
Revenue leakage:
- 10 leads/month, 60% go cold = 6 lost × $3,000 avg = $18,000
- 15% of invoices paid late (cost of capital + chase time) = $750
- 1 client/month leaves early = $2,500
- Total: $21,250/month
Grand total: $137 + $17,200 + $21,250 = $38,587/month
As % of revenue: $38,587 ÷ $5,000 × 100 = 772%
Wait. That can’t be right.
It is. The founder is spending more on ops (in time value) than they’re collecting in revenue. They’re not running a business. They’re running a charity for their clients.
The fix: Managed operations
Here’s what changes with managed operations:
Tool costs:
- Arca (all-in-one): $247/month
- Savings: $137 → $247 (consolidated, but fewer tools)
Admin time:
- 20 hours → 3 hours/week (automation handles the rest)
- 13 hours/month × $200/hour
- Savings: $17,200 → $2,600/month
Revenue leakage:
- Leads going cold: 60% → 20% (instant response)
- Late invoices: 15% → 3% (automatic dunning)
- Early churn: 1/month → 0.5/month (better onboarding)
- Savings: $21,250 → $8,500/month
New total: $247 + $2,600 + $8,500 = $11,347/month
Savings: $38,587 - $11,347 = $27,240/month
New ops % of revenue: $11,347 ÷ $5,000 × 100 = 227%
Still high. But now you can scale. Same ops cost handles 30 clients, 50 clients, 100 clients. The founder isn’t the bottleneck.
The bottom line
Run the calculator. Use your real numbers.
Most founders are shocked. They thought they were spending $500/month on ops. The real number is $10,000-40,000/month when you factor in time and leakage.
The fix isn’t working harder. It’s working differently. Automation handles the repeatable stuff. You handle the high-value stuff.

FAQ
What should I include in operations cost calculation?
Include: (1) Tool subscriptions (scheduling, CRM, invoicing, email, automation), (2) Admin time (your hours × billing rate), and (3) Revenue leakage (lost leads, late payments, early churn). Most businesses find admin time and leakage dwarf tool costs.
How much should a small business spend on operations?
Healthy service businesses spend 10-15% of revenue on operations. Broken operations run 25-40%+. The difference isn’t tool costs — it’s admin time (15-25 hrs/week vs 2-4 hrs/week) and revenue leakage (10-20% lost vs 2-5% lost).
What’s the ROI of managed operations?
Typical ROI: 60-80% reduction in admin time (15-25 hrs/week → 2-4 hrs/week), 50-70% reduction in revenue leakage (better lead response, faster payment collection), and 50-70% reduction in tool costs (consolidation). Payback period: 2-4 weeks.
How do I calculate revenue leakage?
Revenue leakage = Lost leads (leads × cold rate × avg client value) + Late invoices (revenue × late rate × cost of capital) + Early churn (clients lost × avg value × early departure rate). Most businesses lose 10-20% of potential revenue to leakage.
When should I invest in managed operations?
Invest when ops cost exceeds 20% of revenue, or when admin time exceeds 10 hours/week. For most service businesses, this happens at $5,000-10,000/month revenue. Earlier investment = faster path to profitability.
