The language-hour — a better way to price event translation

Event translation has a pricing problem. The cost of simultaneous interpretation is driven by labor — human interpreters, typically two per language, paid by the day. Equipment rental adds a fixed cost. The result is a pricing model that penalizes multilingualism: the more languages you offer, the more you pay, on a linear curve that makes five-language events financially impractical for most organizations.

This article explains an alternative pricing model — the language-hour — and why it makes multilingual events economically viable at any scale. For a broader cost comparison with traditional interpretation, see real-time translation vs simultaneous interpretation.

The traditional model: per-interpreter, per-day

Simultaneous interpretation is priced per interpreter per day. Two interpreters are standard for each language pair, rotating every 20–30 minutes. A two-day conference with three languages requires six interpreter-days of labor.

Factor	Typical cost
Interpreter (per person, per day)	$500–$1,200
Two interpreters per language	$1,000–$2,400 per language per day
Equipment (booths, receivers, wiring)	$3,000–$15,000 per event
Technician (setup + on-site)	$500–$1,500 per day

A two-day conference with three languages costs $8,000–$25,000 before venue, catering, or speakers. Adding a fourth language adds $2,000–$4,800 to the interpretation bill alone.

This pricing structure creates a perverse incentive: organizers limit language offerings to control costs, which means delegates who do not speak the working language follow imperfectly — or not at all.

The language-hour model

The language-hour is a single billing unit: one output language active for one hour.

A one-hour talk translated into three languages consumes three language-hours. A 90-minute panel with two active languages consumes three language-hours. A four-hour conference with five languages consumes 20 language-hours.

The key insight: audience size does not affect cost. Whether 5 or 500 people are listening in French, the language-hour cost is the same. The only variable is how many language tracks you generate and for how long.

Why this model works

Cost is predictable

Traditional interpretation produces quotes that vary by $10,000+ depending on the agency, the language pair, and equipment availability. Language-hour pricing is published upfront. A plan with 25 language-hours per month at a fixed subscription cost means the organizer knows exactly what multilingual support will cost before the event is booked.

More languages cost less, not more

Under the per-interpreter model, adding a language is expensive. Under the language-hour model, adding a language is a marginal increment — it uses more of the same subscription, but there is no separate interpreter to book, no booth to install, and no equipment to rent.

An organizer who budgets for 25 language-hours can allocate them however they choose: 5 languages for a 5-hour event, or 1 language for a 25-hour series. The math is the same.

Audience size is irrelevant

Traditional interpretation requires one receiver headset per listener. A 500-person event needs 500 headsets. A 1,000-person event needs 1,000. The cost scales with attendance.

Real-time translation uses listeners’ own devices. Whether 10 or 300 people join the French audio track, the cost is one language-hour per hour. This eliminates the largest hidden cost of traditional interpretation: the equipment logistics that scale with audience size.

Unused capacity is transparent

Under the per-interpreter model, if a scheduled interpreter is not needed (a session runs short, a language has no takers), the cost is still incurred. Under the language-hour model, unused hours remain in the monthly allocation. They expire at billing cycle end, but they are at least visible — the organizer can see exactly how many hours were consumed and plan accordingly.

How billing works in practice

Language-hours are deducted when a session ends: streaming duration multiplied by the number of distinct output languages used.

Session	Duration	Languages active	Language-hours consumed
Morning keynote	1.5 hours	4	6.0
Afternoon panel	2 hours	3	6.0
Evening briefing	0.5 hours	2	1.0
Total	4 hours	—	13.0

A Starter plan with 25 language-hours per month covers this full day with 12 hours to spare for additional sessions or a safety buffer. For full plan details and allocations, see plans and quotas.

The safety buffer

Paid plans include a hidden safety buffer on top of the monthly allocation: Starter +3 hours, Pro +5 hours, Max +10 hours. This ensures that live sessions are never cut off mid-event if the base allocation is exhausted. No overage charges apply — the buffer simply prevents disruption.

This is a feature of the language-hour model that per-interpreter pricing cannot match. If an interpreter’s shift runs long, you pay overtime. If a session runs 30 minutes over the language-hour allocation, the safety buffer absorbs it silently.

The economic argument for multilingual events

Under the language-hour model, the marginal cost of adding a language approaches zero for organizations with a monthly subscription. This fundamentally changes the calculus:

• A conference that previously offered only English can add French, Spanish, Arabic, and Japanese at no additional cost beyond the subscription. Organizations that hold frequent events, such as corporate town halls, benefit most from this predictability.
• A university that translates lectures for international students can serve 20 languages for the same subscription as 5.
• A government agency that briefs in one language can offer translation in every language its constituents speak.

The language-hour model does not just make multilingual events cheaper. It makes them the default. When adding a language costs nothing extra, the question flips from “can we afford another language?” to “why would we not offer every language our audience speaks?”
