Conference Interpreting Cost & Equipment Price Calculator

How the numbers are built

Conference interpreting is not priced per hour or per word. It is priced per booth per day, and almost every costly surprise on a quote comes from one of four rules.

Two interpreters per booth, not one

Simultaneous interpreting is among the most cognitively demanding professional tasks there is, and interpreters rotate every 20 to 30 minutes. Professional conference interpreting standards treat a minimum of two interpreters per language booth as a standard requirement rather than a preference for any session running longer than an hour. On multi-day events the guidance rises to three per booth so the team can sustain the load across consecutive days. The calculator applies two by default and three once the event runs past a single day.

Booths are a separate line, and the venue can delete it

Mobile booths must meet ISO 4043; permanent installed booths meet ISO 2603. Professional interpreters can decline to work in non-compliant booths, because poor sound insulation causes fatigue and degrades output. If the venue already has built-in booths, that rental disappears from the quote - worth checking before pricing anything else.

Receivers scale with delegates, not languages

Booths scale with languages. Receivers scale with the audience, charged per unit per day, and should be ordered above confirmed headcount to absorb walk-ins, flat batteries and units that wander off.

Relay adds a booth rather than saving one

When no interpreter covers a pair directly, one booth interprets into a pivot language and the others work from that output. It solves a staffing problem and creates a cost one: an extra link in the chain and additional latency for the audience at the end of it.

Common questions

How much does simultaneous interpretation cost per day?

For a standard bilingual conference in major business hubs, expect between $2,000 and $3,200 per day for the two-person interpreter booth alone. When factoring in an ISO 4043 soundproof booth ($600/day), 150 wireless delegate receivers ($600/day), and an on-site AV sound technician ($750/day), a single-booth conference typically totals between $3,950 and $5,150 per day.

How much does an ISO 4043 booth cost to rent?

A full-size, walk-in soundproof booth compliant with ISO 4043 rents for $500 to $850 per day. Modular booths require dedicated freight loading dock access, 2-person union/AV assembly crews, and quiet ventilation units. Tabletop half-booths (used for small workshops or site visits) rent for $250 to $400 per day.

What are standard payment terms and deposit requirements?

Because professional conference interpreters turn down other paying engagements once a date is held, standard industry contracts require a 50% non-refundable deposit upon confirmation. The remaining 50%, alongside verified airfare, hotel, and per diem receipts, is typically invoiced net-14 or net-30 days post-conference.

Why is a half-day almost the same price as a full day?

Most agencies enforce half-day minimums, and an interpreter who blocks a morning has usually lost the afternoon too. Below roughly four hours the saving is real but modest; below one hour, the two-interpreter rule may relax, which is the only point where the cost structure genuinely changes shape.

Does remote interpreting remove the equipment cost?

It removes booths, receivers and the on-site technician, and replaces them with a platform fee that varies enough between providers that guessing on your behalf would be dishonest. The interpreter team requirement does not change - remote simultaneous interpreting still needs a rotating pair.

What is not in this estimate?

Preparation and glossary work, chief interpreter coordination on multi-booth events, overtime beyond the contracted day, cancellation fees, and recording or transcript deliverables. Each is a normal line on a real quote.
