👉 The slang term for "mortgage is 45% of income" might be called the "401K equation." Imagine a person who has saved money over time and wishes to invest it in a high-yield savings account, hoping to grow their wealth over time. However, just like how you could use the 401(K) for future expenses, they can also use it as a cushion when earning an income.
An example sentence: "I've been working hard all my life and saved up enough to pay off that stupid mortgage! Now I'm thinking about shifting funds from my 401K into some more secure investments."
