Como funciona este cálculo (em termos simples)
This calculator uses standard daily-accruing amortization math. Each month, interest is calculated by multiplying your remaining balance by the monthly interest rate (APR ÷ 12). The rest of your payment goes directly to reducing principal. Extra monthly payments bypass interest entirely and reduce the principal directly, creating a compounding reduction in all future interest charges.
Fórmula algorítmica e demonstração matemática
I_m = B \times \left(\frac{\text{APR}}{12}\right), \quad P_m = (M + E) - I_mPremissas do modelo:
- Assumes a fixed interest rate (APR) throughout the loan repayment term.
- Assumes monthly compounding and on-time payments with no late fees or penalty APR triggers.
- Extra payments are applied directly to principal reduction.

Limitações do modelo e condições de contorno
While this engine calculates standard actuarial and consumer finance metrics, real-world finance introduces nuances that no automated model can fully predict:
- Assumes tax rates, inflation indices, and APR rates remain static across modeled projections.
- Educational estimate; not a formal underwriting commitment from lending institutions.
- Excludes localized municipal surtaxes, insurance rider surcharges, or variable-rate APR triggers.
