How We Calculate Helpdesk Costs
Most helpdesk tools charge per agent per month, but the actual cost depends on your billing cycle and required features. Our calculator multiplies the per-agent price by your team size and shows the total monthly cost for each platform.
Tools like Tidio use flat-rate pricing regardless of team size, which can be significantly cheaper for larger teams. Others like Zendesk and Intercom scale linearly with each agent added.
Annual billing typically saves 15-20% compared to monthly. We show both options so you can see the real difference for your team size.
Which Helpdesk Is Cheapest?
For small teams (1-3 agents), Freshdesk's free tier is unbeatable — unlimited agents with email ticketing and a knowledge base at zero cost. Once you need automation or SLA management, Freshdesk Growth at $15/agent/month (annual) remains the most affordable paid option.
For larger teams (10+ agents), flat-rate tools like Tidio become cost-effective since you pay the same whether you have 10 or 50 agents. However, feature depth varies significantly — check our Tidio vs Zendesk comparison for details.
Pricing Isn't Everything
The cheapest tool isn't always the best value. Consider integration needs, feature depth, and scalability. Our detailed pricing breakdowns and in-depth reviews help you evaluate beyond the sticker price.
