Translations for rate in French

Here are paragraphs from public domain books translated:

From the outset, they treated "our saviour" as an old and valued friend. By the time dessert was served, their friendship was well cemented, and private confidences were being exchanged. Arsene related the story of his life, the life of his father as a magistrate, the sorrows of his childhood, and his present difficulties. Gervaise, in turn, spoke of her youth, her marriage, the kindness of the aged Brawford, the hundred millions that she had inherited, the obstacles that prevented her from obtaining the enjoyment of her inheritance, the moneys she had been obliged to borrow at an exorbitant rate of interest, here endless contentions with Brawford's nephews, and the litigation! the injunctions! in fact, everything!

Et dès l’abord on traita « notre sauveur » comme un ami d’ancienne date. Au dessert l’intimité était complète, et les confidences allèrent bon train. Arsène raconta sa vie, la vie de son père, intègre magistrat, les tristesses de son enfance, les difficultés du présent. Gervaise, à son tour, dit sa jeunesse, son mariage, les bontés du vieux Brawford, les cent millions dont elle avait hérité, les obstacles qui retardaient l’entrée en jouissance, les emprunts qu’elle avait dû contracter à des taux exorbitants, ses interminables démêlés avec les neveux de Brawford, et les oppositions ! et les séquestres ! tout enfin !
