Meaning and Usage
The verb "推算" (tuīsuàn) means to infer or estimate a value or outcome based on available information or data. It often involves logical reasoning or calculation rather than direct measurement.
Common Contexts
"推算" is frequently used in scientific, financial, or analytical contexts where exact data may be unavailable, and an approximate figure or conclusion is needed. For example, estimating sales figures, ages of objects, or arrival times.

Nuances and Tips
"推算" implies a reasoned estimate rather than a guess. It is more formal and precise than casual words like "猜" (guess). When using "推算," the speaker suggests a logical basis for the estimate.
Avoid confusing "推算" with "计算" (jìsuàn), which means to calculate exactly. "推算" often deals with incomplete data and approximations.
Summary
Use "推算" when you want to express estimating or inferring a value logically from given information, especially in formal or technical contexts.
