Months to Pay Off vs Monthly Payment
Formula
Debt Payoff Formula
Months = -log(1 - r × D / P) / log(1 + r)
Where D = debt, P = monthly payment, r = monthly rate. Payment must exceed monthly interest (D × r) for the debt to decrease.
Esempio Risolto
$15,000 debt at 12% APR with $400 monthly payments.
- 01Monthly rate = 12% / 12 = 1%
- 02Months = -log(1 - 0.01 × 15000 / 400) / log(1.01)
- 03= -log(0.625) / 0.00995 = 47.2 → 48 months (4 years)
- 04Total paid = 48 × $400 = $19,200
- 05Total interest = $19,200 - $15,000 = $4,200
Domande Frequenti
What is the snowball vs avalanche method?
Snowball: pay smallest debts first for motivation. Avalanche: pay highest interest debts first to save money. Avalanche is mathematically optimal.
How does paying only the minimum affect payoff time?
Minimum payments are typically 1-3% of the balance, which barely covers interest on high-rate debt. On a $15,000 balance at 18% APR, minimum payments could take over 30 years to pay off and cost more in interest than the original debt.
Should I pay off debt or invest?
As a general rule, pay off any debt with an interest rate higher than what you could earn investing. If your debt charges 15% but investments return 10%, paying off the debt is a guaranteed 15% return. Always keep an emergency fund before accelerating debt payments.
