While the International Bank for Reconstruction and Development (IBRD) raises most of its funds on the world's financial markets, IDA is funded largely by contributions from the governments of its richer member countries. Additional funds come from IBRD's income and from borrowers' repayments of earlier IDA credits.

Donors get together every three years to replenish IDA funds. Donor contributions account for about 60% of the SDR 27.3 billion (USD 41.6 billion)  in the IDA15 Replenishment, which finances projects over the three-year period ending June 30, 2011.

A total of 45 countries made pledges to IDA15, the highest number of donors in IDA's history.  Six countries -- China, Cyprus, Egypt, Estonia, Latvia and Lithuania are becoming new IDA donors.  China and Egypt were once IDA borrowers and have joined Korea and Turkey as current donors and prior recipients of IDA's assistance.

IDA helps to reduce poverty by working with other development partners, as well as through its own programs. Development programs are most successful when the borrower country acquires a sense of ownership of the programs through deep involvement in their design and execution. IDA borrower countries now lead in preparing poverty reduction strategies that establish priorities for IDA support. In each country, IDA works with local development partners to ensure that the strategy is carried out in a coherent way and that IDA focuses on areas where it has comparative advantage.

The World Bank (including IDA) is a signatory of the Paris Declaration, a practical, action-orientated roadmap to improve the quality of aid and its impact on development through simplifying and harmonizing donor procedures. Over one hundred Ministers, Heads of Agencies and other Senior Officials endorsed this agreement on 2 March 2005.
