| 1 | Compound interest | What does $X/month become in Y years at R%? |
| 2 | FIRE | When can you stop needing a salary (4% rule)? |
| 3 | Freelance rate | What hourly rate covers taxes, benefits, and admin time? |
| 4 | DCA | Total invested vs portfolio value with dollar-cost averaging |
| 5 | Savings goal | Months until a named target (see [savings calculator guide](savings-calculator-guide.md)) |
