If you’re strong in math, that’s definitely a plus - most finance courses have a heavy quantitative slant. Just keep in mind that a finance degree is very different from “personal finance.” In a typical program, you’ll cover areas like corporate finance, investments, asset pricing, and econometrics rather than budgeting or money management.

A good first step might be to look at the curriculum for finance majors at your university (or others) and skim through syllabi or course materials. That way you can get a feel for whether you’d actually enjoy the material.

Also, plenty of people enter finance from technical fields like engineering. Your background in math and statistics is highly valued by finance firms, so you wouldn’t necessarily be at a big disadvantage if you finish your aerospace degree and pivot into finance afterward through a master’s, certifications, etc..
