# How to calculate the cost of a call?

To calculate the cost of a call, you will need to factor in the following elements:

1. The usage (the length and direction of the call)
2. The phone number
3. The prefix
4. The duration of a call

#### Example: Outbound call with regular number

Here’s an example illustrating how to calculate charges for an outbound call to a UK number.

• The prefix is ‘4420’
• The call duration is 70 seconds.
• The outbound pricing for UK numbers with prefix “4420” is \$0.0031/min.
• The cost for call would be: \$0.0031+ \$0.0031= \$0.0062.
• The cost of a phone number in the UK is \$.80 per month
• Total cost = \$0.8062

Note: the phone number is charged on a monthly basis. The above charges are just an example.

It is not obligatory to purchase a phone number from Plivo to make an outbound call.

Detailed pricing information is available on the Plivo pricing page.

#### Example: Toll-free number

Plivo supports outbound calls using a toll-free number only in the USA and Canada. Here’s an example of making an outbound call using a toll-free number in the US.

• The prefix is “1907”
• The call duration is 70 seconds.
• The outbound pricing for US numbers with prefix “1907”: \$0.1790/min.
• The cost for call: \$0.1790+ \$0.1790= \$0.358.
• The cost of a phone number in US: \$1.00 per month
• Total cost = \$1.358.

Note: The phone number is charged on a monthly basis. The above charges are just an example. It is not obligatory to purchase a phone number from Plivo to make an outbound call if you already have an existing toll-free number.

#### Example: Inbound call with a regular number

Let us consider an example of an inbound call in the United Kingdom.

• The call duration is 70 seconds.
• The inbound pricing for a UK regular number: \$0.0050/min
• The cost for an inbound call is \$0.0050+ \$0.0050= \$0.01
• The cost of a regular phone number in the UK is \$0.80 per month
• Total cost = \$0.81.

Note: the phone number is charged on a monthly basis. The above charges are just an example.

It is mandatory to purchase a phone number from Plivo for an inbound call.
