据初步估计

You usually place this phrase at the very start of a sentence. It sets the stage for the data that follows. For example, 据初步估计，我们需要三千块 (According to preliminary estimates, we need 3,000 yuan). You can also use it in the middle of a sentence after a comma. It functions as a qualifying clause. It is very common in news reports and business meetings. It makes you sound objective and careful with your facts.

Use this when you are in a professional setting. It is perfect for business meetings or project updates. It is also great when planning big events with friends. If someone asks for a budget or a timeline, use this phrase. It shows you are being responsible with your information. You can even use it when texting about arrival times. "According to preliminary estimates, I'll be there in ten minutes."

Do not use this for things that are already certain. If you have the final receipt, don't use it. It sounds weirdly robotic in very intimate or casual moments. For instance, don't tell your partner, "According to preliminary estimates, I love you." That is a quick way to end a date. Avoid it when the stakes are low. You don't need a preliminary estimate for how many fries you want.

Chinese culture often values the concept of 留余地 (leaving room). Being too definitive can be seen as risky. If you are wrong, you might lose face. This phrase allows you to be helpful without being trapped. It reflects a balance between precision and caution. In modern Chinese media, this phrase is a staple. It gives reports an authoritative yet scientifically cautious tone. It is the language of progress and careful planning.

You might also hear 根据初步估算 (According to preliminary calculations). Another common one is 据不完全统计 (According to incomplete statistics). If you are talking about time, you might say 初步预计 (Initially expected). These all serve the same purpose of hedging your bets. They keep the conversation professional while acknowledging that things can change. Use 据初步估计 as your go-to for general numbers and costs.
