Taylor Swift announced her engagement to Travis Kelce with a simple caption: "Your English teacher and your gym teacher are getting married."

But the two are far from working on teacher salaries, and the A-list couple will have a lot to consider when it comes to merging finances.

Swift is the world's richest female musician, and while the three-time Super Bowl champion is no billionaire, Kelce makes far more than any gym coach. Case in point: the engagement ring on Swift's finger is worth an estimated $650,000, according to Forbes.

The pop star and Kansas City Chiefs tight end, both 35, on Tuesday, Aug. 26, revealed they're getting married with a set of romantic photos shot about two weeks prior.

Swift, a shrewd businesswoman who's been vocal about the consumption and sale of her music, is likely to pursue a prenuptial agreement with Kelce before heading down the aisle, financial experts say.
