Formula
Annuity: M = P × r × (1+r)^n / ((1+r)^n − 1), where r = annual rate / 1200. Differentiated: M_k = P/n + (P − P×(k−1)/n) × r. Overpayment = Total payments − Principal.
Domande Frequenti
What is the difference between annuity and differentiated payments?
Annuity payments are equal every month. Differentiated payments start higher and decrease over time because the principal portion is constant while interest decreases.
Which payment type has less overpayment?
Differentiated payments result in slightly less total interest paid, but the initial monthly payments are higher than annuity.
How is the monthly interest rate calculated?
Divide the annual interest rate by 12. For example, 12% annual = 1% monthly, used as 0.01 in the formula.
Can I pay off a loan early?
Most loans allow early repayment. Early payoff reduces total interest. Check your loan agreement for any prepayment penalties.
