租购是一种信贷购物的形式，买方可以用分期付款的方式先取得货品，待付清货款后便可正式拥有货品。有些货品比较昂贵，例如家具、汽车等，卖方通常容许买方以租购方式购买。现在一般租购的运作形式，是由卖方替买方安排财务机构先购买该货品，然后财务机构与买方签订租购合约，在租购合约，会列明买方须在指定期内,定时分期付清货款。在供款期内,买方只是租用货品，待租约期满后，买方有权根据租购合约上订明的售价选择是否购买该货品。当买方选择购买并付清货款后，便得到货品的拥有权。

租购合约内一般列明买方已付的首期、每期供款额和应供期数。有些货品可以免息分期，有些则须支付利息。如果租购的货品是作商业用途,其利息支出可获税务扣减。如果买方要提早终止租购合约，买方必须退回货品，并根据租购合约列明的手续办理。

Hire purchase (abbreviated HP, colloquially sometimes never-never) is the legal term for a contract, in which a purchaser agrees to pay for goods in parts or a percentage over a number of months. In Canada and the United States, a hire purchase is termed an installment plan although these may differ slightly as in a hire purchase agreement the ownership of the good remains with the seller until the last payment is made. Other analogous practices are described as closed-end leasing or rent to own.
