National Giving Week runs from 18 October, during which CAF will target national newspapers, TV and radio stations with PR material about the many ways that the public can support the work of charities.
The week will focus on the benefits of payroll giving by motivating people and businesses to make regular tax-efficient donations to their favourite causes. It will also challenge charity fundraisers to convert existing donors into more effective givers.
Tailored research including a breakdown of the most charitable regions in the UK and people's giving habits will be published throughout the week.
It is intended that the week will become an annual event. John Thurley, head of the campaign, said: "We give less than 1 per cent of gross domestic product to charities, and yet their work is so crucial. We want to focus attention on their valuable work and the benefits of planned, effective giving."
He hopes the campaign will encourage companies to provide news of their payroll giving or employee-volunteering schemes for publication on the national www.givingweek.org website or in the regional press to encourage further giving.
The website, which is already live, stores a wide range of facts and figures to help persuade people and companies to give more effectively.
An interactive giving calculator invites people to type in their gross annual income to discover how much money they would lose if they give away 1 per cent. For someone on a £20,000 salary, this would equate to £200 per year or £16.67 per month.
The calculator shows browsers that if they give with Gift Aid, a £200 donation would expand to £256. It also informs higher rate taxpayers that they can claim 18 per cent tax relief.
