Translation only pays off when there's real, specific demand for your book's genre in the target market, and when you're prepared to market the translated edition there, not just upload it and hope; translation alone, without any marketing behind it in the new market, rarely produces meaningful sales. It's a real investment of money and effort, and deciding well starts with being honest about what translation can and can't do for your book.
This is part of the Complete Guide to Book Translation.
Human literary translation commonly runs $0.08 to $0.30 per word, depending on language pair, genre complexity, and translator experience. For a typical 80,000-word novel, that works out to roughly $6,400 to $24,000, though many self-published authors land somewhere in the $6,000 to $15,000 range for a standard language pair like Spanish, French, or German. Less commonly translated languages, or highly specialized content, can push costs toward the higher end of the range or beyond. AI and machine translation can bring costs down dramatically, sometimes to a small fraction of human rates, with corresponding trade-offs in quality. See Human Translation vs. AI/Machine Translation for Books.
Your genre has strong existing demand in a specific market: romance, thriller, and fantasy, for instance, often have active reader communities in languages like German, Spanish, and Portuguese. You may already have some existing audience or visibility in that language or region, through social media, readers who've asked about a translated edition, or other signals of real demand rather than a guess, and ideally you have a specific, actionable marketing plan for the new market, not just an assumption that translating will organically generate sales the way your primary-language marketing does. Translation is also a stronger bet if your book is part of a series or backlist, since a translated edition can build on momentum from later books in a way a single standalone title often can't, and if you have the budget to treat this as a real investment, not a low-cost experiment, since underfunded, unmarketed translations rarely produce meaningful return.
Be cautious if you're hoping translation alone will meaningfully boost overall sales without dedicated marketing effort in the new market, or if your budget is tight enough that translation would come at the expense of finishing or marketing your next book in your primary language, which often has a more reliable return. It's also a weaker bet if you have no specific market or language in mind and are considering translation mainly because it seems like a natural next step rather than because of identified demand, or if your book is highly dependent on wordplay, cultural references, or voice that's genuinely difficult to render well in another language, which can mean a translated edition reads as a lesser version of the original.
In traditional publishing, when a foreign publisher acquires rights to a book, that publisher typically pays for the translation, not the author. This is worth knowing because a self-published author considering translation is taking on a cost that, in the traditional model, wouldn't typically fall to them. Understanding this helps calibrate expectations: you're making an investment a traditional publisher would only make if they were confident enough in the market to fund it themselves.
Considering a Specific Market?
Entrada Publishing can help you think through whether translation makes sense for your book, and source and vet a qualified translator if you decide to move forward.

Not on its own. Translation without dedicated marketing in the target market rarely produces meaningful sales. It works best as part of a real plan to reach readers in that market, not a low-cost experiment.
In traditional publishing, the foreign publisher acquiring rights typically pays for translation, not the author. Self-published authors considering translation are taking on a cost a traditional publisher would only assume if confident in the market.
Look for a genre with strong existing demand in a specific market, ideally somewhere you already have some audience signal, rather than guessing. See Which Languages Should You Translate Into First?
