Should I take out a loan?
The short answer
Borrow only for assets that produce income or appreciate — education with clear ROI, a home you'll hold, a business with a plan. Never borrow for lifestyle or to preserve appearances.
Signals to weigh
- 01The loan funds an asset, not a consumable.
- 02Expected return exceeds the interest rate by a wide margin.
- 03Monthly payment fits under 15% of take-home with reserves untouched.
- 04You'd still be solvent if the plan takes 2x as long as expected.
How to decide
- Step 1Write the plan in one paragraph: what the loan buys, when it pays back, how.
- Step 2Stress-test at 2x the timeline and 0.5x the return.
- Step 3Shop 3 lenders — rates vary more than you'd expect.
- Step 4Set autopay and a payoff-acceleration line item in your budget.
