This calculator applies standard amortization logic. Each month, interest is added to the current balance and your payment first covers interest, then reduces principal.
Monthly Interest
Interest = Current Balance × (Annual Rate ÷ 12)
Principal Paid
Principal = Total Payment - Interest
New Balance
Ending Balance = Starting Balance - Principal
Extra monthly payments and one-time lump sums directly reduce principal. Because future interest is charged on a smaller balance, payoff time and total interest both decline.
It estimates how many years and months your loan will take to finish. It also shows payoff date, total interest, total paid, and the effect of extra payments.
Income helps connect debt planning with career decisions. You can compare payments against take-home pay and see whether your repayment plan fits job changes, savings goals, or reduced earnings.
Extra monthly payments reduce principal sooner. That lowers future interest charges and often shortens the loan by months or years, depending on balance, rate, and consistency.
It is a single lump sum applied in a chosen month. People often use tax refunds, signing bonuses, commissions, or annual incentives to cut the balance faster.
If your payment does not exceed monthly interest, the balance will not shrink. In that case, the calculator warns you to increase payments or revisit the loan terms.
It is an estimate based on fixed inputs. Real lender schedules may differ slightly because of compounding method, payment timing, fees, rounding, or changing rates.
Yes. It is useful when comparing job offers, planning a career break, moving to a lower-stress role, or setting a debt target before self-employment.
Exporting helps you keep a record of assumptions, review schedules later, and share repayment scenarios with a spouse, advisor, recruiter, or financial planner.
