假設、結果解讀與常見錯誤
計算假設
- The values entered for loan amount and rate a are accurate for the scenario.
- Rates and recurring amounts remain constant for the period represented by the formula.
- Provider fees, taxes and timing differences are excluded unless they are explicit inputs.
如何解讀結果
- Treat the main number as a planning estimate, not a quote, approval or guarantee.
- Compare at least a baseline, lower and higher assumption before deciding.
- Use the result together with the related loan calculators for a broader view.
應避免的常見錯誤
- Entering a percentage as a decimal when the field expects a whole percent.
- Comparing results that use different time periods or omit different fees.
- Rounding inputs early or treating an estimated rate as guaranteed.
