I Built AI Prompts to Calculate Transcription Costs

A few months ago, I wrote our AI Transcription Pricing guide—a comprehensive breakdown of what every major service charges. It's useful, but I kept getting the same question: "Okay, but what will it cost me for my situation?"

The pricing tables show per-minute rates. What people actually need is: "I have 12 podcast episodes averaging 45 minutes each. What's my monthly cost on different services?" Or: "My research project has 40 interviews. What's my total budget?"

So I built a set of AI prompts that act as personalized pricing calculators. You paste in your specific numbers, and the AI does the math across multiple services, including hidden costs most people miss.

Quick Navigation

Why Static Pricing Tables Fall Short

Here's the pricing table from our comparison guide:

Service Pay-Per-Use Subscription Real Cost Per Hour
BrassTranscripts $6.00 flat rate None $6.00
Otter.ai N/A $16.99/mo (1,200 min) $10.00*
Temi $0.25/min None $15.00
Rev AI $0.25/min N/A $15.00

*Assumes full utilization

The problem? That asterisk. "Assumes full utilization" hides the real question: Will you actually use 1,200 minutes every month?

A podcaster releasing weekly 60-minute episodes uses 240 minutes monthly. On Otter's $16.99 plan, their effective cost is $4.24/hour—great deal. But a podcaster releasing biweekly 30-minute episodes uses 60 minutes monthly. Same $16.99 plan, effective cost: $17/hour. Terrible deal.

The prompts below calculate these real-world scenarios automatically.

The Podcaster Calculator

I built this one first because podcast transcription has predictable, recurring patterns. The prompt accounts for episode frequency, average length, and whether you need speaker identification.

AI Prompt: Podcast Transcription Cost Calculator

📋 Copy & Paste This Prompt

Calculate my podcast transcription costs across different services based on my production schedule.

MY PODCAST DETAILS:
- Episodes per month: [NUMBER]
- Average episode length: [MINUTES]
- Number of speakers per episode: [NUMBER]
- Do I need speaker labels? [YES/NO]
- Do I need timestamps? [YES/NO]
- Output format needed: [TXT/SRT/VTT/JSON]

CALCULATE FOR THESE SERVICES:

1. **BrassTranscripts** (Pay-per-use)
   - $2.50 flat for 0-15 min files
   - $6.00 flat for 16-120 min files
   - Includes speaker ID and all formats

2. **Otter.ai** (Subscription)
   - Free: 300 min/month
   - Pro: $16.99/month for 1,200 min
   - Business: $30/user/month for 6,000 min

3. **Temi** (Pay-per-use)
   - $0.25/minute
   - Speaker ID included

4. **Descript** (Subscription + Transcription)
   - Free: 1 hour/month
   - Creator: $15/month (10 hours)
   - Pro: $30/month (30 hours)

5. **Rev AI** (Pay-per-use)
   - $0.25/minute base
   - Speaker diarization included

FOR EACH SERVICE, PROVIDE:
- Monthly cost calculation with math shown
- Annual cost projection
- Cost per episode
- Cost per audio hour (effective rate)
- Whether my needs exceed plan limits
- Hidden costs I might miss (speaker ID add-ons, format charges, storage)

THEN RECOMMEND:
- Best option for my specific usage pattern
- Break-even point where switching services makes sense
- What would change my recommendation (more/fewer episodes, longer/shorter)

Example: What This Returns

When I tested with "4 episodes per month, 45 minutes each, 2 speakers, need speaker labels":

BrassTranscripts: 4 × $6.00 = $24/month ($288/year)

  • $6/episode, $8/hour effective rate
  • All formats included

Otter Pro: $16.99/month for 180 minutes used of 1,200 available

  • $16.99/month ($204/year)
  • But: 85% of paid capacity unused
  • Effective rate: $5.66/hour
  • Looks cheaper, but you're paying for 1,020 minutes you don't use

Temi: 180 min × $0.25 = $45/month ($540/year)

  • Most expensive option for this volume

Recommendation: For 4 episodes at 45 minutes, Otter Pro appears cheapest but wastes 85% of capacity. BrassTranscripts costs $7/month more but you pay only for what you use. If episode count or length increases, the calculation shifts.

That's the kind of personalized analysis a static table can't provide.

The Research Project Calculator

Research transcription is different from podcasting—it's project-based rather than recurring. You have a fixed number of interviews to transcribe, often with tight deadlines and budget constraints.

AI Prompt: Research Project Budget Calculator

📋 Copy & Paste This Prompt

Calculate total transcription budget for my research project.

PROJECT DETAILS:
- Total number of interviews: [NUMBER]
- Average interview length: [MINUTES]

- Do I need verbatim transcription? [YES/NO]
- Do I need speaker attribution? [YES/NO]
- Timeline: [DAYS/WEEKS to complete all transcription]
- Budget constraint: [AMOUNT or "flexible"]

SPECIAL REQUIREMENTS:
- Language(s): [LIST LANGUAGES]
- Technical terminology: [FIELD/DISCIPLINE]
- Confidentiality level: [STANDARD / IRB-COMPLIANT / HIPAA]

   - Include estimated review/correction time at $[HOURLY_RATE]/hour

2. **AI Transcription (Other services)**
   - Compare Otter, Temi, Rev AI at current rates

3. **Human Transcription (Rev)**
   - $1.50/minute for standard
   - $3.00/minute for verbatim
   - Include typical turnaround time

4. **Hybrid Approach**
   - AI transcription + professional review
   - Estimate total cost and time

FOR EACH OPTION, CALCULATE:
- Total transcription cost
- Estimated review/correction hours needed
- Total project cost (transcription + review time)
- Timeline feasibility
- Risk factors (accuracy for technical content, speaker attribution reliability)

PROVIDE:
- Recommended approach for my budget and timeline
- What I'd sacrifice by choosing the cheapest option
- What I'd gain by choosing the most expensive option
- Break-even analysis: at what volume does human transcription make sense?

Why I Built This One

A grad student emailed asking about transcribing 25 interviews for their dissertation. They'd gotten quotes from human transcription services ($2,400) and were trying to decide if AI transcription ($150) was "good enough."

The real question wasn't cost—it was risk. Would they spend 40 hours correcting AI errors, making the "cheap" option more expensive in time? The prompt above forces that calculation.

For their specific case (clear audio, two speakers, non-technical content), AI transcription with 2-3 hours of review per interview was still dramatically cheaper than human transcription. But for a medical researcher with technical terminology and multiple overlapping speakers, the calculation would flip.

The Sales Team Calculator

Sales teams have a different calculation entirely. They're comparing transcription costs against conversation intelligence platforms like Gong ($100-150/user/month). The question isn't "which transcription service is cheapest?" but "can DIY transcription replace enterprise software?"

AI Prompt: Sales Team Transcription ROI Calculator

📋 Copy & Paste This Prompt

Calculate whether DIY transcription can replace our conversation intelligence platform.

CURRENT SITUATION:
- Number of sales reps: [NUMBER]

The Insight That Prompted This

I wrote our Sales Call Transcription guide after realizing most sales teams assume they need Gong. For a 10-person team at $100/user/month, that's $12,000/year.

DIY transcription + AI analysis costs maybe $3,000-4,000/year for the same team. But the calculation only works if you don't need real-time coaching, automatic CRM sync, or enterprise compliance features.

This prompt forces teams to check which features they actually use—often revealing they're paying for capabilities they never touch.

The Content Creator Calculator

Content creators have the most variable transcription needs. Some weeks they produce three videos; some weeks zero. Subscriptions punish this variability.

AI Prompt: Content Creator Transcription Budget Planner

📋 Copy & Paste This Prompt

Plan my transcription budget as a content creator with variable output.

MY CONTENT PRODUCTION:
- Primary platform: [YOUTUBE/PODCAST/COURSES/MIXED]
- Content pieces per month: [RANGE, e.g., "2-6"]
- Average content length: [MINUTES]
- Busiest month (last year): [PIECES] pieces, [TOTAL HOURS] audio
- Slowest month (last year): [PIECES] pieces, [TOTAL HOURS] audio

WHAT I USE TRANSCRIPTS FOR:
- [ ] YouTube captions/subtitles
- [ ] Blog post creation
- [ ] Social media quotes
- [ ] Show notes
- [ ] Course materials
- [ ] SEO optimization
- [ ] Accessibility compliance

CALCULATE THREE SCENARIOS:

**Scenario A: Slow Month**
- Minimum expected content
- Calculate costs across services

**Scenario B: Average Month**
- Typical content volume
- Calculate costs across services

**Scenario C: Busy Month**
- Maximum expected content
- Calculate costs across services

FOR EACH SCENARIO, COMPARE:
1. BrassTranscripts (pay-per-use): $6/file over 15 min
2. Otter Pro ($16.99/mo): 1,200 min included
3. Descript Creator ($15/mo): 10 hours included
4. Descript Pro ($30/mo): 30 hours included

ANALYSIS:
- Which service wins in each scenario?
- What's my expected annual cost with variable production?
- At what consistent volume does subscription beat pay-per-use?
- Hidden costs for my specific use cases (SRT export, speaker ID, etc.)

RECOMMENDATION:
- Best primary service for my variability pattern
- Backup option for overflow months
- Annual budget range to plan for

The Variable Production Problem

Here's why this matters: A YouTuber told me they subscribed to Descript Pro ($30/month) because they "sometimes" produce 20+ hours of content monthly.

Looking at their actual production over 12 months: they hit 20+ hours twice. Six months they produced under 5 hours. Four months were 5-15 hours.

Annual cost on Descript Pro: $360 Annual cost on BrassTranscripts (actual hours): ~$180

They were paying double because subscription pricing made them plan for peak months instead of actual usage.

The "Should I Subscribe?" Calculator

This is the meta-prompt—it answers the fundamental question underlying all transcription pricing decisions.

AI Prompt: Subscription vs Pay-Per-Use Decision Calculator

📋 Copy & Paste This Prompt

Help me decide: should I subscribe to a transcription service or pay per use?

MY USAGE HISTORY (be honest):
- Transcription hours last 3 months: [MONTH1], [MONTH2], [MONTH3]
- Expected hours next 3 months: [MONTH1], [MONTH2], [MONTH3]
- Highest single month ever: [HOURS]
- Lowest single month ever: [HOURS]
- How predictable is my usage? [VERY/SOMEWHAT/UNPREDICTABLE]

SUBSCRIPTION OPTIONS I'M CONSIDERING:
1. [SERVICE]: $[PRICE]/month for [MINUTES] minutes
2. [SERVICE]: $[PRICE]/month for [MINUTES] minutes

PAY-PER-USE BASELINE:
- BrassTranscripts: $6/hour (files over 15 min)

CALCULATE:

**Utilization Analysis**
- Average monthly usage: [calculate from history]
- Usage variability: [standard deviation or range]
- Subscription utilization rate: [% of included minutes I'd actually use]

**Cost Comparison**
- Subscription annual cost: [fixed]
- Pay-per-use annual cost: [based on actual usage pattern]
- Effective per-hour rate for each option

**Break-Even Analysis**
- Hours/month where subscription becomes cheaper
- How often do I actually hit that threshold?

**Risk Assessment**
- Cost of unused subscription capacity
- Cost of pay-per-use in high-volume months
- Which risk is more expensive for my pattern?

DECISION FRAMEWORK:
- If utilization would be >80%: Subscription likely wins
- If utilization would be 50-80%: Calculate carefully
- If utilization would be <50%: Pay-per-use likely wins
- If usage is highly variable: Pay-per-use reduces risk

RECOMMENDATION:
- Clear recommendation with reasoning
- What would change my recommendation
- Suggested review period (when to recalculate)

The 80% Rule

Through building these calculators, I've landed on a simple heuristic: subscriptions only make sense if you'll use 80%+ of included capacity consistently.

Below 80% utilization, you're paying for unused minutes. And "consistently" is key—hitting 80% six months out of twelve still means you overpaid half the year.

Most people overestimate their consistency. The prompt forces you to look at actual history, not optimistic projections.

The Enterprise Volume Calculator

For organizations transcribing serious volume, the calculation includes factors individuals don't face: team coordination, compliance requirements, and volume discount negotiations.

How I Use These Prompts

When someone asks me "what will transcription cost?", I don't point them to a pricing table anymore. I ask which of these scenarios fits their situation, then have them run the relevant prompt with their actual numbers.

The prompts work with ChatGPT, Claude, or any capable AI assistant. Paste the prompt, fill in your specifics, and you get a personalized calculation that accounts for your actual usage pattern—not hypothetical "average user" assumptions.

A few tips from using these myself:

  1. Be honest about history. The prompts ask for actual past usage because people consistently overestimate future needs. If you've never transcribed more than 5 hours in a month, don't plan for 20.

  2. Run multiple scenarios. Your needs might change. Knowing the break-even points helps you recognize when to switch approaches.

  3. Include your time. Some prompts ask about review/correction time. A "cheaper" option that requires 3x the review time isn't actually cheaper.

  4. Recalculate quarterly. Usage patterns shift. A decision that made sense in January might not make sense in July.

The goal isn't finding the absolute cheapest option—it's finding the option that costs least for your specific situation. These prompts force that personalized calculation.
