Daniel is a single software tester whose take-home pay is 5,200 dollars a month. His essential monthly outgoings are a mortgage payment of 2,150 dollars, utilities of 310 dollars, groceries of 640 dollars, insurance premiums of 285 dollars, a car loan payment of 420 dollars and other essential costs of 195 dollars. He also spends about 900 dollars a month on dining out, travel and hobbies, which he would stop immediately if he lost his job. He holds 26,000 dollars in a money market account as his emergency reserve. Measured against his essential monthly outgoings, how many months of reserve does Daniel hold?
- A5.0 months, because the reserve is measured against his monthly take-home pay of 5,200 dollars
- B6.5 months, because the reserve is measured against essential monthly outgoings of 4,000 dollars Correct
- C5.3 months, because the reserve is measured against essential outgoings plus his 900 dollars of discretionary spending
- D7.3 months, because the reserve is measured against essential outgoings with the 420 dollar car loan payment removed
Why A is wrong: Take-home pay is easy to reach for and is sometimes used as a rough proxy, but it includes the monthly surplus he is not obliged to spend, so it overstates what a job loss would actually cost him each month and understates the reserve.
Why B is correct: Essential outgoings total 4,000 dollars a month, and 26,000 dollars divided by 4,000 dollars is 6.5 months, which is the measure the stem asks for and the one that reflects what an income interruption would really cost.
Why C is wrong: Including discretionary spending is the standard error here, and the stem explicitly says Daniel would stop that spending on losing his job, so those 900 dollars are not a cost the reserve has to cover.
Why D is wrong: Some candidates strip debt service out on the assumption that a lender would grant forbearance, but a car loan payment falls due whether or not the borrower is working, so removing it understates the monthly need and flatters the reserve.
