AI-moderated platforms like Koji bring that down to **as low as €1 per text interview and €3 per voice interview** at the annual rate (€2 and €6 pay as you go), with reports auto-generated: a text interview is 1 credit, a voice interview is 3, and a credit costs €1.00 to €2.00 depending on how you buy. For a typical 30-interview discovery study, traditional methods land between **€2,700 and €7,800**, while running the same study on Koji costs **about €80 to €200**.\n\nThis calculator walks through the real line items so you can build an honest budget — or justify a switch to AI-moderated research.\n\n## What Goes Into the Cost of a User Interview\n\nMost teams underestimate research spend because they only count the obvious items. The real cost stack has six layers:\n\n1. **Participant incentive** — €25 to €150 per session depending on persona seniority\n2. **Recruiting fee**: €40 to €120 per participant via panel platforms. On Koji there is no platform fee: bring your own audience, or approve a per-respondent quote in credits from Panel recruit before you launch\n3. **Scheduling and coordination** — 30–45 minutes of researcher time per slot\n4. **Moderator time** — 60 minutes per session plus 30 minutes of prep\n5. **Transcription** — €0.10 to €1.50 per minute, or 4–6× hours of researcher review\n6. **Analysis and synthesis** — typically equal to or greater than the interview time itself\n\nTraditional research budgets often only show line items 1 and 2, then surprise teams when items 3–6 consume the rest of the quarter.\n\n## Per-Interview Cost: Traditional vs AI\n\n### Traditional moderated interview (mid-market, B2B SaaS persona)\n\n| Line item | Low | High |\n|---|---|---|\n| Recruiting fee | €40 | €120 |\n| Participant incentive | €25 | €150 |\n| Scheduling overhead (0.5h × €60/h) | €30 | €30 |\n| Moderator time (1.5h × €60/h) | €90 | €90 |\n| Transcription | €6 | €60 |\n| Analysis (1.5h × €60/h) | €90 | €90 |\n| **Per-interview total** | **€281** | **€540** |\n\n### Koji AI-moderated interview\n\n| Line item | Cost |\n|---|---|\n| Text interview | 1 credit (from €1.00 at the annual rate, €2.00 at most) |\n| OR voice interview | 3 credits (from €3.00, €6.00 at most) |\n| Recruiting | Built in, no platform fee: bring your own audience, or approve a per-respondent quote in credits from Panel recruit |\n| Auto-transcription | included |\n| Auto-analysis (themes + structured data) | included |\n| Real-time report aggregation | included (5 credits per refresh) |\n| **Per-interview total** | **€1 to €6** |\n\nA credit's price depends only on commitment: **€2.00 pay as you go, €1.82 down to €1.33 in one-time packs (€100 to €2,000), about €1.20 on monthly plans (Starter €199 for 165 credits, Pro €499 for 415, Scale €999 for 830), and exactly €1.00 on annual plans** with all credits granted on day one. That annual rate is where the €1 text interview and €3 voice interview come from. You are never tied to a subscription. There is no overage. You pay as you go, and you only ever pay for the conversations that bring insights. For team-wide deployments above ~100 interviews per month, or anywhere SSO, single-tenant infrastructure, or a signed DPA is required, the [Enterprise plan](/enterprise) (from €500/month or €6,000/year) is typically the better structure.\n\n## Calculator: 30-Interview Discovery Study\n\nLet us run the math on a common scenario — 30 user interviews to validate a new feature.\n\n### Traditional (low estimate)\n\n- Recruiting: 30 × €40 = **€1,200**\n- Incentives: 30 × €25 = **€750**\n- Researcher time (3h/interview avg): 90h × €60 = **€5,400**\n- Transcription: 30 × 60min × €0.10 = **€180**\n- **Total: €7,530**\n\n### Traditional (mid estimate)\n\n- Recruiting + incentives: €4,500\n- Researcher time + analysis: €5,400\n- Transcription + tooling: €600\n- **Total: ~€10,500**\n\n### Koji, text interviews\n\n- 30 text interviews × 1 credit = 30 credits\n- 2 report refreshes × 5 credits = 10 credits\n- 40 credits: **€80** pay as you go, covered by the **€100 pack** (55 credits, with 15 left over), or **€40** at the annual rate\n\n### Koji, voice interviews\n\n- 30 voice interviews × 3 credits = 90 credits\n- 2 report refreshes × 5 credits = 10 credits\n- 100 credits: **about €190** (a €100 pack plus 45 credits pay as you go), or **€100 flat** at the annual plan rate of €1.00 per credit\n\nThat is a **40× to 130× cost reduction** depending on mode and how you compare to the low or high end of traditional methods. And you finish in days, not weeks.\n\n## Where the AI Savings Actually Come From\n\nThe biggest cost drivers in traditional research are **researcher time** and **recruiting overhead** — not the participant incentive. Koji eliminates both:\n\n- **Self-serve interview link.** Share one link and dozens of participants can interview themselves in parallel. No scheduling, no Calendly tag, no rescheduling.\n- **AI moderator.** A Koji interview runs like a real conversation — the AI asks the question, listens, and follows up with up to three probing questions per topic (configured by `maxFollowUps` in the question definition). That replaces a researcher sitting on each call.\n- **Auto-transcription + auto-analysis.** Every conversation is transcribed, themed, and mapped to your structured questions automatically. The themes, quotes, and per-question distributions are ready in real time.\n- **Quality-gated billing.** Only conversations that hit the quality gate (score 3 or higher) consume credits. If a participant abandons after 30 seconds or types nonsense, no credit is charged.\n\nFor structured questions (NPS, willingness-to-pay, ranking, etc.), Koji additionally auto-aggregates per-question distributions — meaning your synthesis time on quantitative questions drops to near zero.\n\n## Recruiting Cost: AI Saves You Here Too\n\nThe panel-recruit model charges €40 to €120 per participant on top of the incentive — that is pure overhead. You do not need your own audience. If you have customers, users, employees or a list, send them the interview link, embed it in your product, or let Koji call them. If you do not, open [Panel recruit](/docs/panel-recruitment), describe who you want to hear from, and Koji finds them across 130+ countries. You see the price per completed interview in credits before you launch, you can soft-launch 10% first, and you only pay for interviews that pass the quality check. Recruiting, interviewing, analysis and the report all happen in one study, so nothing is exported, re-uploaded or re-tagged on the way. Quoting is free; launching is on paid plans. And because Koji interviews are async and self-serve, your own channels are cheap too:\n\n- **In-product link** to existing users (free)\n- **Email list invitation** (free, except small CRM costs)\n- **Community / Slack / LinkedIn outreach** (free)\n- **Paid ads to a custom landing page** (typically €5–€20 per qualified completion)\n\nKoji also includes **screener questions** — a configurable intake form that filters participants by role, segment, or any custom attribute before the interview begins. This replaces the panel platform’s screening fee for many B2C and prosumer studies.\n\n## When Traditional Research Still Wins\n\nLet us be honest about the tradeoffs. Traditional moderated interviews are still the right call when:\n\n- You need **high-empathy ethnographic depth** with body language and a moderator reading the room\n- Your participants are **regulated personas** (e.g., specific medical specialists) that a panel cannot target, where a specialist recruiter is the only path\n- You are running a **single high-stakes interview** with an executive where fees pale next to the strategic value\n\nFor everything else — discovery, feature validation, NPS root-cause, willingness-to-pay, customer journey mapping, churn analysis, message testing — AI-moderated interviews on a platform like Koji are dramatically cheaper, faster, and more rigorous.\n\n## How to Estimate Your Own Budget\n\nUse this five-step framework to build a defensible 2026 research budget:\n\n1. **List your studies for the quarter.** A typical product team runs 4–8 studies per quarter.\n2. **Pick your sample size per study.** 8–15 for early discovery, 25–50 for validation, 100+ for quantitative segments.\n3. **Choose the modality.** Text mode for higher volume and async; voice for nuanced, conversational depth.\n4. **Calculate Koji cost.** `studies × interviews_per_study × (1 or 3 credits) × €1 + plan fee`.\n5. **Compare to traditional.** Multiply by €280 (low) or €450 (mid) to see what you would otherwise spend.\n\nFor most teams, Koji's **Starter plan at €199/month** covers 165 credits: 55 voice interviews or 165 text interviews, enough for several full studies per month. Annualized at €1,990 with all 1,990 credits upfront at €1.00 each, a full year of research costs about as much as **four** traditional moderated interviews.\n\n## FAQ Snapshot\n\n- **What does each Koji credit cost?** From €1.00 on annual plans up to €2.00 pay as you go. You choose the route. There is no overage, and you only ever pay for the conversations that bring insights.\n- **Do I pay for failed interviews?** No — the quality gate ensures only scored 3+ conversations consume credits.\n- **Are voice and text interviews priced the same?** No — text = 1 credit, voice = 3 credits.\n- **What does report refresh cost?** 5 credits per refresh, billed only when you regenerate analysis.\n\n## Related Resources\n\n- [Plan Comparison Guide](/docs/plan-comparison-guide): credits, packs, and plans explained\n- [Structured Questions Guide](/docs/structured-questions-guide) — the 6 question types that drive auto-aggregation\n- [How to Automate User Research](/docs/how-to-automate-user-research) — operating an AI-first research practice\n- [Koji vs UserTesting](/docs/koji-vs-usertesting) — head-to-head feature and pricing comparison\n- [Generating Research Reports](/docs/generating-research-reports) — what real-time report aggregation looks like\n- [Plan Comparison Guide](/docs/plan-comparison-guide): choosing the right way to buy for your team\n\n## Further reading on the blog\n\n- [Koji vs UserTesting: AI-Powered vs Panel-Based Research (2026)](/blog/koji-vs-usertesting-2026) — UserTesting averages $36,265/year for SMB teams.
