Unforgettable Costing Tool

The Costing Tool below allows you to determine the cost of your study on the Unforgettable system. It will also calculate how much the participants would be paid for the data you require. To use the tool, select which data sources you are interested in. Then enter the length of time you would like data for. The data that you require may already have been collected, so this time does not necessarily mean that you will need to wait for data to accumulate.

Number of Participants establishes how many people you wish to recruit.

Currency is the currency in which you will pay. Participants specify the currency in which they wish to be paid and Unforgettable takes care of any currency conversion required.

Data Source indicates the type of data that you will receive. For a detailed description of the data source, click the name of the data source (blue text below). If the data source is a survey, clicking the survey name will take you to the survey.

Cost per data point is the cost that you pay for each event generated of this type. For some data sources, the cost per data point decreases for longer time periods.

Min Number of Events to Qualify is the minimum number of events that a participant must have to be added to your data set and to qualify for compensation. This restriction ensures that you have enough data from each participant to analyse.

Payment Ceiling is the maximum number of events you will pay for. For data sources such as emails or social media posts, the number of events a participant can generate is not bounded. We enforce this ceiling to ensure that you know what your maximum cost will be. Note you will receive any additional events that the participants generate(d) during the collection period, you just won't pay for them.

Participant payment is the amount that a participant will be paid for agreeing to complete the study. These numbers can be used in ethics applications and participant information sheets.
