Model multiple loans and card balances using the same monthly payment budget, showing interest and time to debt freedom under balance-first or interest-first prioritisation.
A ₹50,000 card at 36% and ₹1,00,000 consumer loan at 18% typically favour avalanche when surplus cash goes to the more expensive debt after minimum repayments.
Accrue monthly interest at APR/12, pay each debt’s minimum, then allocate remaining monthly budget to the selected priority. Freed payments roll to other open debts. Maximum projection is 600 months.
A stable-rate planning model, not an issuer amortisation statement. Charges, compounding frequency, rate revisions, prepayment fees and additional borrowings are excluded.
Mixing annual rates and monthly rates can distort savings. Any budget below contractual minimums is rejected; the simulation does not forgive interest or assume a lender waiver.
Avalanche normally pays less interest. Snowball can be easier to stick to because small debts close sooner.
All else equal, applying surplus funds to highest APR first generally reduces interest.
Some borrowers prefer visibly closing smaller balances as a behavioural goal.
