On Prolific, we endorse the principle of 'ethical rewards'. We believe fair pay leads to better data quality. We therefore recommend you pay participants at least £7.50/$9.60 per hour, while the minimum pay allowed is £5.00/$6.50 per hour.
To find out exactly what your study costs, please login, go to step 1 in your dashboard, and enter (1) how many participants you want to recruit and (2) how much you want to pay each participant. The system will give you a quote based on these parameters which includes our service charge and any VAT if applicable.
We add a 33% service fee on top of the total participant cost.
This service charge is used to provide all of the services that keep the Prolific platform running, like software development, hosting, customer support, and payments processing.

You must fund your studies up-front by topping up your account in advance of running the studies. We then manage the payments to your participants.
The quickest way to top up your account is by making a card payment which is very easy and instant. It can be some days for bank transfers to be reflected on your account balance, due to our internal checks. We can't accept payments by cheque.
Please note that some banks/card providers may impose additional charges for international transfers. Please get in touch with your bank if you would like further information related to transfer fees.
