You put $75K base in your budget. Done. But that's not what an SDR costs — that's what they earn. The real number is higher, and if you haven't run the full math, you're going to get surprised mid-year.
Here's the breakdown most founders never see.
The Cost That Shows Up on Payroll (Visible)
The obvious stuff first. A US-based SDR in 2026:
| Cost Item | Annual | Monthly |
|---|---|---|
| Base Salary | $70,000 – $85,000 | $5,833 – $7,083 |
| Employer taxes + benefits (25-30%) | $17,500 – $25,500 | $1,458 – $2,125 |
| SDR tools (Outreach, Apollo, LinkedIn Sales Nav) | $3,000 – $7,200 | $250 – $600 |
| CRM seats + overhead | $1,200 – $3,600 | $100 – $300 |
| Management overhead (10-20% of manager time) | $8,000 – $20,000 | $667 – $1,667 |
| True monthly cost | $99,700 – $141,300/year | $8,308 – $11,775/mo |
That's right — the number you put in the budget was probably 40-60% below the real cost. And we haven't even gotten to the expensive parts.
Ramp Time: The Invisible 3-6 Month Tax
Your new SDR isn't productive on day one. It takes 3-6 months to ramp: learning your product, understanding your ICP, developing email voice, getting consistently rejected until they find their rhythm.
During ramp, you're paying full salary for roughly 40% of the output. If you hire in January, you're essentially paying $5-8K/month for $2-3K/month of work until around April.
Cost of ramp per hire: $15,000 – $30,000
Most founders don't account for this because it's diffused — it shows up as lower-than-expected pipeline in Q1, not as a line item. But it's real money.

Hidden Costs That Break the Math
Three costs that show up in almost every company but almost never show up in the original budget:
1. Turnover
SDR turnover runs 35-50% annually in most SaaS companies. Some sources put it higher. The job is brutally hard — high rejection, low prestige, consistent pressure. The average SDR tenure is 14-18 months.
When they leave: you pay to rehire, you pay to re-ramp, you lose institutional knowledge, and your pipeline gaps while you're back at zero. Each departure costs $30,000 – $60,000 in direct replacement costs alone — let alone the pipeline cost.
2. Inconsistency between reps
Your best SDR writes emails that book meetings. Your newest SDR writes emails that damage your sender reputation. The same job, radically different outputs. With a human, quality fluctuates with energy, morale, skill level, and tenure.
With an AI SDR, every email hits the same quality floor. The variance is gone.
3. Attention cost
This one doesn't show up on any spreadsheet, but it's real: every hour your manager spends reviewing and correcting SDR output is an hour not spent on strategy, hiring, and closing. The review-and-fix loop is a tax on your management team's time that compounds over every hire.
The Math: Meetings Per Dollar
Let's compress this into a single metric founders can use: meetings booked per dollar spent.
Here's a reasonable setup for a human SDR with full costs:
- Annual investment: ~$125K fully loaded (salary + benefits + tools + management)
- Ramp-adjusted output: ~75% of year-2 productivity in year 1
- Output: ~150 qualified conversations per year at steady state
- Meetings per $1,000: ~1.2 meetings
Now, consider this: your AEs are spending 20-30% of their time on prospects who will never close — sourced by your SDR, but wrong-fit. The real meetings-per-dollar is even worse when you factor in downstream cost of disqualified pipeline.
With Revuro at $299/month ($3,588/year), the math changes completely. Same prospect research, same personalized outreach, same follow-up sequences — but the investment is 35x lower.
Human SDR: ~1.2 qualified meetings per $1,000 invested
Revuro: AI-powered outreach at $299/month — no salary, no ramp, no turnover risk, no review bottleneck. Same ICP, same sequences, full autonomy.
How AI SDRs Change the Cost Equation
AI doesn't just reduce the cost — it changes the shape of the cost structure. With a human SDR:
- Cost is fixed whether you're in a busy quarter or a slow one
- Output is variable based on energy, mood, and skill level
- Capacity is capped at 40 hours/week
- Onboarding is 3-6 months; offboarding is instant the day they quit
With an AI SDR:
- Cost is fixed and predictable: $299/month
- Output quality is consistent — the 11th email is as strong as the 1st
- Capacity is 168 hours/week with zero overtime
- Onboarding is hours (describe your ICP, done); no quitting, no vacation
The comparison is stark enough to warrant its own table:
| Factor | Traditional SDR | Revuro |
|---|---|---|
| Monthly cost | $8,300 – $11,775 | $299/mo |
| Ramp time | 3-6 months | Same day |
| Availability | 40 hrs/week (M-F) | 24/7/365 |
| Output consistency | Varies by energy, skill, morale | Stable quality floor |
| Turnover risk | 35-50% annually | Zero |
| Review bottleneck | Human approves every email | None — autonomous |
| Follow-up persistence | Often gives up after 1-2 tries | 5-7 touch sequences, always |
The gap isn't about cutting costs. It's about removing the structural constraints that make human SDR performance ceiling-limited. You can read more about this in our first post: Why Your AI SDR Needs to Sleep (And Why Revuro Doesn't).
What to Do With This Math
If you're currently paying for a human SDR — do the full accounting before assuming the budget is working. Factor in the hidden costs. Calculate your real meetings-per-dollar. If the number comes back worse than expected, it's not because your SDR is bad — it's because the job has structural cost ceilings that no individual performer can overcome.
If you're scaling outreach for the first time — this is the moment to run the math honestly. The cost of a human SDR isn't just the salary. It's the salary plus benefits plus tools plus management plus ramp plus turnover plus the variance in quality that comes with any human system.
Revuro starts at $299/month. No contracts, no onboarding fees, no per-seat pricing. You set the ICP and the AI handles everything else — compare it to what you're paying now.
Stop paying $10K/month for a 40-hour SDR.
Revuro is $299/month. It runs 24/7, follows up consistently, and books meetings while you focus on closing.
