Total Debt Calculator
Every balance added into one visible total — the starting point of any payoff plan. Live calculator with worked steps and charts.
Calculator
Smallest balance goes first for snowball ordering.
This debt payoff calculator compounds monthly at APR ÷ 12: interest is charged on the outstanding balance each month, and anything extra you enter attacks the priority balance immediately.

How this is calculated
Every outstanding balance is added into a single total so the full obligation is visible in one number.
What drives the result
Minimums are calibrated to keep accounts current while maximising lender interest, so the tail of a minimums-only payoff stretches for years. Directing every spare dollar at one priority debt — and rolling each freed minimum forward — collapses the tail: the same dollars that barely dented five balances retire them one by one.
Recommendations
- •Knowing the single total is step one — feed it into a payoff-date plan next.
- •Include every balance, even small ones; hidden debts break payoff plans.
Educational Content
Introduction
Unsecured debt is priced monthly: each balance accrues interest at APR ÷ 12, minimums cover that charge first, and only the remainder cuts principal. Every figure on this page — payoff date, interest bill, savings — comes from simulating that loop, which is why raising the payment or cutting the rate moves everything at once.
Concept Explanation
Minimums are calibrated to keep accounts current while maximising lender interest, so the tail of a minimums-only payoff stretches for years. Directing every spare dollar at one priority debt — and rolling each freed minimum forward — collapses the tail: the same dollars that barely dented five balances retire them one by one.
Applications
Benefits
- •One consistent simulation behind every date and dollar figure
- •Interest bills exposed in full, not hidden in minimums
- •Side-by-side strategy pricing instead of rules of thumb
- •Dates and milestones concrete enough to automate
Limitations
- •Assumes fixed APRs and on-time payments throughout
- •Excludes late fees, penalty APRs and new spending unless modelled
- •Lender day-count and rounding conventions differ by dollars, not direction
- •Variable-rate debts reprice with their index
Best Practices
- •Automate every minimum plus the extra on payday
- •Aim all extra dollars at one priority debt
- •Confirm overpayments reduce principal rather than prepaying dues
- •Freeze new borrowing on debts being cleared
Common Misconceptions
Practical Tips
- •List hidden debts too — forgotten balances break plans.
- •Update the total monthly.
