Avalanche Method (Mathematically Optimal)
Pay minimums on all debts, put every extra rupee toward the highest interest rate debt first. Saves the most money in total interest.Snowball Method (Psychologically Effective)

| Below 20% | Comfortable | Normal repayment |

Credit cards charge 36–42% APR in India. No investment can match that return. If you have credit card debt, paying it off is the highest-return financial move available to you — period.
| Credit Card Balance | Monthly Interest (36% APR) | If You Pay Only Minimum |
|---|---|---|
| ₹50,000 | ₹1,500 | Takes 5+ years to clear |
| ₹1,00,000 | ₹3,000 | Takes 8+ years to clear |
| ₹2,00,000 | ₹6,000 | Can take 10+ years |

Should I use savings to pay off debt?
If your debt interest rate is higher than your savings return — yes (with an emergency fund exception). Keep 1–2 months' expenses as emergency fund, then throw everything else at high-interest debt. Credit card debt at 36% vs savings earning 4% = clear math.
Is debt consolidation worth it?
If you can consolidate multiple debts into one loan at a significantly lower rate (e.g., replacing 36% credit card debt with a 12% personal loan), yes. But only if you don't rack up new credit card debt afterwards — otherwise you've doubled your problem.
How do I stay motivated during debt payoff?
Track your progress visually (debt thermometer or chart). Celebrate milestones (each debt cleared). Use the snowball method if motivation is your challenge. Tell someone your goal — accountability matters.
