Banking & Deposit Calculators
Fixed deposits, recurring deposits, savings interest, overdraft, credit card payoff — every banking number you need.
From senior-citizen FDs to credit-card minimum-payment traps, these calculators cover the full range of everyday banking decisions. Each uses the actual formula banks apply — quarterly compounding for FDs, daily balance for savings, monthly compounding for credit cards.
The FD Calculator includes TDS thresholds (₹50,000 for non-seniors, ₹1,00,000 for seniors) and a 0.5% senior-citizen rate bump. The Credit Card calculator detects when your monthly payment is too low to ever clear the balance, and shows you the minimum amount needed.

Choose FD when you have a lumpsum to deposit upfront and want the highest fixed-income return — quarterly compounding maximises growth. Choose RD when you can save a fixed amount monthly but don't have a lumpsum. RD interest is slightly lower than FD because each monthly deposit compounds for less time, but the discipline of regular saving makes it valuable for goal-based saving.
Both are taxed at slab rate. Both deduct TDS at 10% if interest crosses the threshold (with PAN; 20% without). For tax-free fixed-income, consider PPF (15-year lock) or NSC (5-year, taxable but Section 80C eligible).
Avoiding the credit-card minimum-payment trap
Credit cards in India typically charge 36–48% annualized (2.5–3.5% monthly). Paying only the "minimum due" (often 5% of the balance) means you pay almost entirely interest — the principal barely moves. A ₹1,00,000 outstanding at 3% monthly with only minimum payments takes over 7 yearsto clear and costs ~₹78,000 in interest.
Use the Credit Card calculator to see exactly what monthly payment clears your balance in 12, 18 or 24 months. If your payment is below the monthly interest, the calculator flags it as "never amortizes" and tells you the minimum required to start reducing the balance.
