Short answer: HubSpot's Prospecting Agent charges credits only when it surfaces a contact for outreach, and according to HubSpot, a surfaced net-new contact costs about 100 HubSpot Credits, which is roughly $1.00 at HubSpot's overage rate of about $0.01 per credit. So your monthly cost is close to (contacts surfaced per month × 100 credits), minus the credits already included in your plan, with anything beyond that billed at the overage rate. On the Professional tier, you get 3,000 credits included each month, enough to surface about 30 contacts before you pay a cent more.
That's the headline number. The useful version is knowing how to calculate your number before you turn the Agent on, because the difference between a $30 month and a $300 month is entirely in how you scope the work. This guide walks through exactly how the credits work, how to estimate your spend, and the free Prospect Agent Planning Kit we built to do the math for you.
A quick, important caveat: HubSpot's credit rates, included allotments, and pricing can change, and beta features may start consuming credits over time. Treat the numbers here as a planning framework, not a quote. Always confirm the current rates in your own HubSpot portal or with your HubSpot representative, if anything looks different from what we describe.
Key Takeaways
- The Agent charges per surfaced contact, not per email sent. Surfacing a net-new contact for outreach costs about 100 HubSpot Credits (~$1.00).
- Included credits cover a real amount of work. Professional includes 3,000 credits per month. Credits reset monthly and do not roll over.
- Your monthly cost is a simple formula: contacts surfaced per month × 100 credits, minus included credits, times the overage rate.
- Scope is the whole game. A too-broad target market is what turns a predictable budget into a runaway one. We burned 20,000 credits in 30 days learning that.
- Plan before you launch. Our free Prospecting Agent Planning Kit turns a lead target into a dollar figure before the Agent spends anything.
What Are HubSpot Credits, and Why Is AI Priced This Way?
Before the Prospecting Agent, most HubSpot features were covered by your seat-based subscription. AI changed that. Running an agent has a real, variable compute cost every time it acts, so HubSpot, like most of the software industry, moved usage-based AI features onto a credit model. You can read HubSpot's own background on why AI is priced this way in its AI credits buyer's guide and its explainer on usage-based pricing.
The mechanics are straightforward. HubSpot Credits power usage-based AI features including the Prospecting Agent, Customer Agent, and Data Agent. Credits are consumed only when the AI actually completes a task for you, not just for having the feature switched on. Every seat-based plan includes a monthly allotment of credits that scales with your highest subscription tier, those credits reset each month, and any unused credits expire rather than roll over. HubSpot's full credits and billing documentation and its AI credits product page are the source of truth for the current rates and the exact included amounts.
When you exceed your included credits, you have two options: buy capacity packs (sold in blocks of 1,000 credits) that set a predictable monthly limit, or turn on pay-as-you-go overages, billed at HubSpot's current overage rate of about $0.01 per credit in increments of 10. As an Elite HubSpot Solutions Partner, we run this model every day, and the good news for budgeting is that it's predictable once you know the one number that drives it.
How the Prospecting Agent Uses Credits
Here is the mechanic that matters, and the one most people miss: the Prospecting Agent charges you when it surfaces a contact for outreach, and a surfaced net-new contact costs about 100 credits. At the overage rate, that's roughly $1.00 per contact. That single number drives your entire budget.
A few related facts round out the picture:
- Included credits do a lot of work. On the Professional tier, 3,000 included credits cover roughly 30 surfaced contacts every month before any overage applies. Higher tiers include more.
- Credits reset monthly and expire. There is no rolling balance, so budgeting is a monthly exercise, not an annual one.
- You can cap it. HubSpot lets you set an account-level maximum monthly credit limit and per-feature limits, so the Agent pauses instead of surprising you. We recommend setting one before your first play.
How to Calculate Your Monthly Credit Cost
You can estimate your spend with one formula. This is exactly what the Planning Kit automates.
Monthly credits = accounts enrolled × contacts surfaced per account × 100
Monthly cost = (monthly credits − included credits) × $0.01
Let's walk through a realistic "Expected" scenario on the Professional plan:
- 40 accounts enrolled in a play
- 1.5 contacts surfaced per account, so 60 contacts surfaced
- 60 contacts × 100 credits = 6,000 credits used
- Subtract 3,000 included credits, leaving 3,000 in overage
- 3,000 × $0.01 = about $30 for the month
Now see how scope swings the number:
| Scenario | Accounts | Contacts/account | Contacts surfaced | Credits used | Overage cost (Professional) |
|---|---|---|---|---|---|
| Conservative | 25 | 1.2 | 30 | 3,000 | $0 (covered by included) |
| Expected | 40 | 1.5 | 60 | 6,000 | ~$30/month |
| Aggressive | 100 | 2.0 | 200 | 20,000 | ~$170/month |
The lesson jumps off the table. The Agent's cost is linear with how many contacts you ask it to surface, so the size of your target market, not the Agent itself, is your budget lever.
The Variables That Quietly Blow Up Your Budget
We learned this the expensive way. In our first thirty days running the Prospecting Agent, we burned through 20,000 credits by pointing it at every ICP segment we could think of, all at once. Being an Elite Solutions Partner didn't spare us the lesson. As I put it in our 90-day write-up:
"The Agent doesn't need less capability. It needs a tighter brief."
Most of our credit waste was driven by four scoping mistakes (so, avoid these if you can):
- Target market too wide. Define a market by industry alone and the Agent will happily surface contacts across the whole thing, at 100 credits each.
- Too many research topics. HubSpot limits the number of research topics per play. Fill 20 with near-duplicates and half of them are noise you're paying for.
- Loose persona precision. Well-known titles surface efficiently. Newer or fuzzy titles have thinner data, so the Agent overspends hunting for a signal.
- Mixing play types in one play. Expanding into known accounts and chasing net-new companies are two different motions. Combine them and the messaging goes generic and the credit accounting gets muddy.
Our lead growth strategist, Krystina Gillenwater, framed the fix as a set of lanes we now use with clients:
-
AI and agents handle intelligence and speed, sequences
-
Tasks in Hubspot handle execution and accountability
-
Workflows handle enrollment and governance
-
The rep owns judgment and the final send.
Keep each in its lane and both your results and your credit burn should stay more under control.
A Faster Way: The Prospecting Agent Planning Kit
After that 20,000-credit month, we shut everything down and rebuilt the workflow from scratch. That rebuild became the Prospecting Agent Planning Kit, a Google Sheet that turns a monthly lead target into a dollar figure before the Agent spends anything.
The Kit does the sizing for you. You choose your play type (expand vs. net-new), size your segments, and enter your lead targets. Its HubSpot Credit Calculator applies the credits-per-lead and your plan's included credits across Expected, best-case, and worst-case scenarios, then rolls up an all-in monthly cost, including an Apollo credit tab if you're enriching with Apollo data. It is the difference between running the Agent on budget and spending several times that because you skipped the sizing step.

In Conclusion
The HubSpot Prospecting Agent costs about 100 credits, or roughly $1.00, every time it surfaces a contact for outreach. Multiply that by the contacts you plan to surface each month, subtract your included credits, and you have your budget.
The Agent's price is predictable. What makes it feel unpredictable is scope, so tighten the brief, size the plan before you launch, and confirm the current rates in your portal. Do that, and the Prospecting Agent becomes a line item you can defend, not a meter you're afraid to watch.

FAQs: HubSpot Prospecting Agent Credits
How much does it cost to run the HubSpot Prospecting Agent?
It charges about 100 HubSpot Credits per contact it surfaces for outreach, which is roughly $1.00 at HubSpot's overage rate of about $0.01 per credit. Your monthly cost is the number of contacts surfaced times 100 credits, minus your plan's included credits.
How many credits does one prospect cost?
Surfacing a net-new contact is about 100 credits. Pulling a contact's data through the native Apollo email reveal is about 1 credit. Rates can change, so confirm in your portal.
How many HubSpot Credits are included in my plan?
It depends on your highest subscription tier. Professional includes 3,000 credits per month, and higher tiers include more. Your exact allotment is shown in your HubSpot account.
Do unused HubSpot Credits roll over?
No. Credits reset at the start of each monthly usage period and any unused credits expire.
What happens if I run out of credits?
Credit-based features pause until your next reset, unless you buy additional capacity packs (sold in blocks of 1,000) or turn on pay-as-you-go overages billed at about $0.01 per credit.
Can I cap how much the Prospecting Agent spends?
Yes. You can set an account-level maximum monthly credit limit and per-feature limits, so the Agent stops instead of overspending.
Why did our credit spend blow up?
Almost always because the target market was too broad. The Agent surfaces contacts across whatever market you point it at, at 100 credits each. Tightening segments, personas, and research topics as well as setting a cap on your credit consumption is the fix.
