The cost of toll free service includes a monthly fee and a per-minute charge. Monthly fees typically do not exceed $0-$20 per month, although special features may add slightly to this figure.

The per-minute charge can be a flat rate, or it can be banded, which means it varies according to the distance a particular call travels. In either case, per minute charges decrease as you attain higher calling volumes. Businesses receiving just a few calls a day can expect to pay about 20¢ per minute. Firms receiving thousands of minutes in calls per month should expect to pay 14¢ per minute or less.

Companies receiving more than 20,000 minutes per month on their toll free line may find a dedicated line to be more cost-efficient. Although installation fees can be high, per minute rates are much lower.
