A flat fee, also referred to as a flat rate or a linear rate, refers to a pricing structure that charges a single fixed fee for a service, regardless of usage. Less commonly, the term may refer to a rate that does not vary with usage or time of use.
There are flat rates in the postal service, regarding the delivery of items. Postage companies use different forms of post, boxes or envelopes, to avoid having to weigh items. The on-hand cost lets consumers identify the cost and removes the hassle of estimate the cost for items.
The United States Postal Service offers flat-rate pricing for packages selling different postage options varying in size and shape. That provides consumers with an array of options upfront, creating a sense of ease. When shipped in higher volumes, it saves money but there are issues if both the flat rate and regular delivery systems are used simultaneously.
Flat rate also passes into advertising. Purchasing advertisements on websites such as Facebook, Twitter and YouTube is sold a flat rates on the size (with a surcharge for images and posts) and length of the advertisement (video costs extra). Advertising on YouTube pitches at a flat rate of $0.30 per view. When a person runs by the YouTube home page, search page, or wherever the ad is running, the charge is $0.30.
Tradesmen such as electricians, plumbers, and mechanics, also often charge flat rates to cover their labour for their services. In a survey in 2014 in Australia, the average labour rate for a painter was $39.92 per hour.
American telecommunications companies commonly offer a flat rate to residential customers for local telephone calls. However, a regular rate or Message Rate is advantageous for those who make only a few short calls per month. Flat rates were rare outside the US and Canada until about 2005, but they have since become widespread in Europe for both local and long distance calls and are now also available for mobile phone services, both for traditional GSM/UMTS voice calls and for Mobile VoIP.
Most VoIP services are effectively flat-rate telephony services since only the broadband internet fees must be paid for PC-to-PC calls, and the calls themselves are free. Some PC-to-telephone services, such as SkypeOut offer flat rates for national calls to landlines.
