If you’re debating between quickly eloping to Vegas or having a massive wedding with 300 guests, a performance by Tom Jones, and a flyover by the Blue Angels — listen up.

Slate.com put together a calculator that figures out how much money you’d have now if you took your wedding budget and invested it instead. They used the S&P 500 as the basis for their investing.

You just put in how many years you’ve been married, and how much you spent on your wedding — and it delivers the mortifying truth.

Like, if you got married five years ago and spent $10,000, it would be worth more than $20,000 now.

If you got married 20 years ago and spent $10,000, it would be worth more than $65,000 now.
