Frequently asked questions
Q: Is this the same formula banks use? A: Yes, the basic formula is identical. Banks add their own assumptions for risk and margins on top, but the underlying math is the same.
Q: How often should I recalculate? A: Whenever your inputs change significantly — income, expenses, interest rates, or life stage. For most people, that’s once a year during annual planning.
Q: What’s the biggest mistake people make? A: Optimistic assumptions. People tend to under-estimate expenses and over-estimate returns. Use conservative numbers and you’ll be right more often than wrong.
