I'd like a Sharia-compliant savings product: which choices exist and how is the profit set?

Islamic banks offer savings accounts, deposits and certificate-like products, which some call sukuk (not to be confused with the government's sovereign sukuk). The main difference is the way the return is described: the bank calls it profit, not interest, and the advertised figure is usually an expected profit, settled in the end on the bank's actual results under its rules; some banks state that their rates are expected and subject to reconciliation, and others publish the profits they actually distributed each quarter. So any calculation built on that figure is an estimate, not a contractual number. These products are also built on structures such as mudaraba or wakala, which the bank explains in its terms. A Sharia ruling on a specific product is a matter for the religious authority you trust, not for a comparison site. When comparing, compare Islamic products with one another at the same amount, term and profit-payout frequency. Check the product's key-facts statement for its structure, how the profit is computed and settled, the distribution frequency and the break terms.
