Law Firms: When Is Bulk Transcription Worth It?
You have 47 deposition recordings sitting in a case folder. Each one needs a working transcript for case prep. The question isn't whether to transcribe them — it's whether to upload them one at a time or use bulk.
BrassTranscripts offers both single-file and bulk transcription, and the pricing structures are different enough that the wrong choice costs real money. This guide breaks down exactly when bulk saves you money, when single-file is actually cheaper, and includes an AI prompt that calculates your specific breakeven point.

Single-File vs. Bulk Pricing
BrassTranscripts single-file pricing uses two flat-rate tiers based on duration, while bulk pricing uses volume-based per-file rates regardless of duration.
Single-File Pricing:
| Duration | Price |
|---|---|
| 1-15 minutes | $2.50 per file |
| 16-120 minutes | $6.00 per file |
Bulk Pricing:
| Volume | Price Per File | Batch Cost |
|---|---|---|
| 1-19 files | $90 flat | $90 |
| 20-49 files | $4.50 | $90-$220.50 |
| 50-99 files | $4.00 | $200-$396 |
| 100-249 files | $3.50 | $350-$871.50 |
| 250+ files | $3.00 | $750+ |
Both include automatic speaker identification, files up to 2 hours each, and concurrent processing. Single-file delivers 4 output formats (TXT, SRT, VTT, JSON); bulk delivers TXT format.
The critical difference: single-file pricing varies by duration, bulk pricing doesn't. A 7-minute file and a 90-minute file cost the same rate in bulk. That's where the math gets interesting.
When Bulk Saves Money (And When It Doesn't)
BrassTranscripts bulk transcription charges a flat per-file rate regardless of how long each file is — a 7-minute recording and a 90-minute deposition cost the same. The entry price is $90 flat for 1-19 files, then $4.50/file for 20+. Whether bulk saves money depends entirely on the mix of short and long files in your batch.
Why the mix matters: Single-file pricing charges $2.50 for files under 15 minutes and $6.00 for files over 15 minutes. Bulk charges one flat rate for every file. So long files are cheaper in bulk, but short files are cheaper as single uploads.
- A 45-minute deposition: $6.00 single vs. $4.00-$4.50 bulk (bulk wins)
- A 10-minute phone call: $2.50 single vs. $4.00-$4.50 bulk (single wins)
The breakeven question isn't about individual files — it's about the whole batch. If most files are long, bulk saves real money. If most are short, you're paying more per file than you need to.
The Breakeven Formula
The breakeven depends on what percentage of your files exceed 15 minutes. Each long file you add tilts the math toward bulk; each short file tilts it toward single. Here's the breakeven for each tier:
At 20-49 files ($4.50/file — $90 minimum for 20 files):
- Each file over 15 min saves $1.50 vs. single ($6.00 - $4.50)
- Each file under 15 min costs $2.00 more vs. single ($4.50 - $2.50)
- Breakeven: 57% of files must be over 15 minutes
- Example: 20 files, 12 long + 8 short → Single $102, Bulk $90 → Bulk saves $12
- Example: 20 files, 10 long + 10 short → Single $85, Bulk $90 → Single saves $5
At 50-99 files ($4.00/file):
- Each file over 15 min saves $2.00 vs. single ($6.00 - $4.00)
- Each file under 15 min costs $1.50 more vs. single ($4.00 - $2.50)
- Breakeven: 43% of files must be over 15 minutes
At 100-249 files ($3.50/file):
- Each file over 15 min saves $2.50 vs. single ($6.00 - $3.50)
- Each file under 15 min costs $1.00 more vs. single ($3.50 - $2.50)
- Breakeven: 29% of files must be over 15 minutes
At 250+ files ($3.00/file):
- Each file over 15 min saves $3.00 vs. single ($6.00 - $3.00)
- Each file under 15 min costs $0.50 more vs. single ($3.00 - $2.50)
- Breakeven: 14% of files must be over 15 minutes
The larger the batch, the more forgiving the math. At 250+ files, bulk is cheaper unless nearly everything is under 15 minutes. At the entry tier of 20 files, you need more than half your files to be over 15 minutes to beat the $90 minimum.
Real Scenarios From Legal Practice
Scenario 1: Discovery Package — 60 Deposition Recordings
A litigation team has 60 recorded depositions averaging 45-90 minutes each. All files exceed 15 minutes.
| Method | Calculation | Total |
|---|---|---|
| Single-file | 60 × $6.00 | $360.00 |
| Bulk (50-99) | 60 × $4.00 | $240.00 |
| Savings | $120.00 (33%) |
Bulk wins by $120. Every file benefits from the lower rate.
Scenario 2: Client Interview Archive — 30 Mixed-Length Recordings
A solo practitioner has 30 client intake recordings: 12 are under 15 minutes (quick phone screens), 18 are over 15 minutes (full consultations).
| Method | Calculation | Total |
|---|---|---|
| Single-file | (12 × $2.50) + (18 × $6.00) | $138.00 |
| Bulk (20-49) | 30 × $4.50 | $135.00 |
| Savings | $3.00 (2%) |
Barely worth it. The 12 short files nearly cancel out the savings on the 18 long files. At 60% long files, this batch is right at the breakeven point for the 20-49 tier.
Scenario 3: Paralegal's Weekly Upload — 25 Short Status Calls
A paralegal records 25 status calls per week, mostly 5-12 minutes each. Only 3 are over 15 minutes.
| Method | Calculation | Total |
|---|---|---|
| Single-file | (22 × $2.50) + (3 × $6.00) | $73.00 |
| Bulk (20-49) | 25 × $4.50 | $112.50 |
| Difference | -$39.50 (bulk costs more) |
Single-file wins by $39.50. With only 12% long files, bulk doesn't make sense.
AI Prompt: Bulk vs. Single-File Cost Calculator
BrassTranscripts built this prompt so legal teams can paste their file details — or just estimate counts and durations — and get an instant cost comparison between single-file and bulk transcription pricing.
The prompt handles two input modes: exact file lists with durations, or rough estimates like "about 50 files, most around 30 minutes." It calculates total costs, savings, and tells you which option wins.

You are a transcription cost calculator for BrassTranscripts pricing. Calculate whether single-file or bulk transcription is cheaper based on the user's files. PRICING REFERENCE: Single-file: - Files 1-15 minutes: $2.50 each - Files 16-120 minutes: $6.00 each Bulk (flat per-file rate regardless of duration): - 1-19 files: $90 flat (no per-file breakdown — you pay $90 whether you have 1 or 19 files) - 20-49 files: $4.50/file - 50-99 files: $4.00/file - 100-249 files: $3.50/file - 250+ files: $3.00/file INSTRUCTIONS: 1. Accept the user's input in ANY of these formats: - Exact file list with durations (e.g., "12 files at 45 min, 8 files at 10 min") - Rough estimates (e.g., "about 50 files, most are 30-60 minutes") - File count with percentage split (e.g., "75 files, roughly 70% over 15 minutes") - Just a file count (e.g., "40 files" — ask: "About how many are over 15 minutes versus 15 minutes or under?") 2. For rough estimates, interpret vague language as: - "most" = 75% - "about half" / "half" = 50% - "almost all" = 90% - "a few" = 3 files - "a handful" = 5 files If estimates produce fractional file counts, round to the nearest whole file. Make sure totals still add up. 3. Calculate both options: SINGLE-FILE TOTAL: - Count files ≤15 min × $2.50 - Count files >15 min × $6.00 - Sum = single-file total BULK TOTAL: - If 1-19 files: bulk total = $90 flat - If 20+ files: determine volume tier, then total files × tier rate = bulk total 4. Present results as a clear comparison table: - Single-file total - Bulk total - Difference (savings or overpay) - Percentage saved - Verdict: which option wins and by how much 5. Calculate the breakeven using this exact formula: breakeven_percentage = (bulk_rate - 2.50) / (6.00 - 2.50) × 100 breakeven_file_count = round(breakeven_percentage / 100 × total_files) Reference values (use these, do not recalculate): - $4.50 tier: 57% breakeven - $4.00 tier: 43% breakeven - $3.50 tier: 29% breakeven - $3.00 tier: 14% breakeven Show as: "Breakeven at this tier: Bulk becomes cheaper when X% or more of your files exceed 15 minutes — that's Y out of Z files." 6. If the difference is under 10%, call it a close call. If the user gave rough estimates and the result is close, note that a slightly different duration mix could change the answer. EXAMPLE OUTPUT FORMAT: ## Your Cost Comparison | | Single-File | Bulk (50-99 tier) | |---|---|---| | 35 files over 15 min | 35 × $6.00 = $210 | — | | 15 files under 15 min | 15 × $2.50 = $37.50 | — | | Bulk rate | — | 50 × $4.00 = $200 | | **TOTAL** | **$247.50** | **$200.00** | **Verdict: Bulk saves $47.50 (19%)** Breakeven at this tier: Bulk becomes cheaper when 43% or more of your files exceed 15 minutes — that's 22 out of 50 files. Your mix is 70% — well above breakeven.

When to Just Use Single-File
Bulk isn't always the answer. Use single-file transcription when:
- You have a small batch of short files — bulk charges $90 flat for 1-19 files, so if your few files are all under 15 minutes, single-file at $2.50 each is cheaper
- Most files are under 15 minutes — short calls, voicemails, and brief interviews cost $2.50 each with single-file vs. $3.00-$4.50 in bulk
- Files arrive one at a time — if you're transcribing recordings as they come in rather than processing a batch, single-file is simpler
- You need a 30-word preview before paying — single-file includes a preview before purchase; bulk processes all files upfront
For ongoing transcription needs with mixed volumes, many law firms use both: bulk for case discovery batches and single-file for daily recordings.

Frequently Asked Questions
When does bulk transcription save money over single-file pricing?
Bulk transcription saves money when most of your files are longer than 15 minutes. Single files under 15 minutes cost $2.50 each, while the lowest bulk rate is $3.00 per file. For files over 15 minutes, single-file pricing is $6.00 each — bulk pricing at $3.00-$4.50 per file saves 25-50% on those longer recordings. The breakeven depends on your specific mix of short and long files.
What is the minimum number of files for bulk transcription?
BrassTranscripts bulk transcription starts at $90 flat for 1-19 files. The volume tiers are: 20-49 files at $4.50/file, 50-99 files at $4.00/file, 100-249 files at $3.50/file, and 250+ files at $3.00/file. Each file can be up to 2 hours long, and all files are processed concurrently with automatic speaker identification included.
Can I mix short and long audio files in a bulk upload?
Yes. BrassTranscripts bulk transcription charges a flat per-file rate regardless of individual file duration — a 6-minute file and a 90-minute file cost the same within your volume tier. This makes bulk pricing especially advantageous when you have a mix of file lengths, because the longer files benefit from the flat rate while shorter files would have been cheaper individually.
How fast does bulk transcription process compared to single files?
BrassTranscripts processes bulk files concurrently rather than sequentially. A batch of 50 files completes in roughly the same time as processing a few files individually — typically 1-3 minutes per hour of audio. All files include automatic speaker identification, which is critical for depositions and multi-party recordings.
Do bulk transcripts include speaker identification?
Yes. Every BrassTranscripts transcription — single file or bulk — includes automatic speaker identification at no extra cost. The AI labels each speaker (Speaker 1, Speaker 2, etc.) with timestamps throughout the transcript. For depositions and interviews with 2-6 participants, this eliminates manual speaker tagging entirely.
