# Billable messages calculator

How many service messages go out a month, how many stay billable after the free allowance, and how far that drops if you group them or use a Flow. The rate per message is yours to enter, from Meta's list for your customers' country: there are no rate figures here.

Example calculation. You need to take the rate per message from Meta's list for your customers' country: there are no rate figures here.

Conversations per monthOutbound messages per conversation todayOutbound messages if you group them or use a Flow% of conversations that start from an ad with a free windowRate per message (USD, from Meta's rate card)

**1,800** service messages per month today, not counting ads

**800** billable today (after the first 1,000 free)

**USD 16** estimated Meta cost today

**900** messages with grouping or a Flow

**0** billable

**USD 0** estimated cost (saving of USD 16)

The estimate is for a single WhatsApp line: with more than one number, each one has its own 1,000 free messages. Confirm the cost of a Flow with your provider.
