15 financial calculators for everyday decisions
Compare loan costs, plan deposits and explore savings goals in Indian rupees. Enter your own figures: the example rates below are assumptions, not current bank offers. Results are rounded to the nearest rupee.
How to use: choose a tool, change its inputs, then select Calculate. Open “Method and assumptions” before using a result. The starting results illustrate the default inputs.

Loan EMI
Estimate the instalment on a home, vehicle or personal loan.
Monthly EMI: ₹10,379
Total instalments: ₹6,22,751
Total interest: ₹1,22,751
Method and assumptions
Monthly reducing balance; rate stays constant. Excludes fees, insurance and rate resets. EMI = P × i ÷ (1 − (1+i)^−n); at zero interest, EMI = P/n.
Fixed deposit maturity
Estimate a cumulative FD with quarterly compounding.
Maturity before tax: ₹1,23,144
Interest earned: ₹23,144
Method and assumptions
Maturity = P × (1 + annual rate/4)^(months/3). Fractional quarters are an estimate. Before tax; actual bank day-count and premature-withdrawal rules may differ.
Recurring deposit estimate
Build a deposit through monthly instalments.
Estimated maturity: ₹2,00,686
Total deposited: ₹1,80,000
Interest before tax: ₹20,686
Method and assumptions
Deposits arrive at the start of each month. Monthly rate is (1 + annual rate/4)^(1/3) − 1, approximating quarterly compounding. Actual bank instalment dates, rounding and penalties can change the result. Before tax.
Loan prepayment
Compare keeping your EMI after an immediate part-payment.
EMI retained: ₹12,668
New remaining months: 102
Interest saved before fees: ₹1,29,752
Interest after prepayment: ₹3,90,358
Method and assumptions
Keeps the original EMI and reduces the tenure. Models monthly interest and the smaller final payment. Excludes lender fees and assumes no further rate changes. Confirm prepayment conditions with your lender.
Balance transfer
Compare two loans over the same remaining tenure.
Current EMI: ₹13,215
New EMI: ₹12,399
Net saving after costs: ₹87,981
Simple cost recovery: 13 months
Method and assumptions
Same principal and tenure; costs paid upfront. Net saving is the difference in total instalments less switching costs. Simple break-even = costs/monthly EMI saving; it ignores time value and future rate resets.
Deposit insurance estimate
Check your exposure at one DICGC-insured bank.
Combined eligible balance: ₹4,80,000
Within insurance cap: ₹4,80,000
Above insurance cap: ₹0
Method and assumptions
For one depositor in the same right and capacity across every branch of ONE insured bank. Principal plus interest share the ₹5 lakh cap. Repeat separately for another bank. Assumes eligible deposits and no set-off; not a payout determination.
Credit card utilisation
Measure balances as a proportion of total card limits.
Credit utilisation: 30.0%
Credit score: Not predicted by this tool
Method and assumptions
Utilisation = reported balances / credit limits × 100. This does not calculate or predict a CIBIL score. Reporting dates and other credit-history factors matter. Balances above limits can produce more than 100%.
Monthly investment projection
Explore a hypothetical monthly saving or investment plan.
Projected value: ₹9,14,730
Contributed: ₹6,00,000
Hypothetical growth: ₹3,14,730
Method and assumptions
End-of-month contributions; monthly rate = annual assumption/12. This is a smooth-return illustration, not a forecast or guarantee. Market returns can be negative; excludes fees and tax.
Lump-sum growth
Project one investment at an assumed annual return.
Projected value: ₹2,15,892
Hypothetical growth: ₹1,15,892
Method and assumptions
Annual compounding: future value = P × (1+r)^years. The rate is your assumption, not a current offer or guaranteed market return. Before fees and tax.
Inflation and purchasing power
Compare future costs with the purchasing power of cash.
Future cost of same purchase: ₹1,62,889
Purchasing power of unchanged cash: ₹61,391
Method and assumptions
Future cost = amount × (1+inflation)^years. Purchasing power = amount/(1+inflation)^years. Constant inflation is an illustration, not a forecast.
Monthly savings target
Estimate the contribution needed for a future goal.
Monthly contribution needed: ₹5,233
Projected existing savings: ₹1,34,885
Method and assumptions
Existing savings compound monthly; new deposits arrive at month-end. Target should already include expected inflation. Returns are assumed and taxes/fees excluded.
Emergency fund
Choose a cash buffer based on essential expenses.
Target buffer: ₹1,80,000
Amount still needed: ₹1,20,000
Months to target: 12
Method and assumptions
Target = essential monthly expenses × chosen months. No investment return assumed. The suitable buffer depends on income stability, dependants and insurance; six months is an example, not a rule.
Retirement corpus projection
Estimate savings at retirement using your own assumptions.
Projected corpus: ₹1,09,63,426
Total contributions: ₹35,00,000
Hypothetical growth: ₹74,63,426
Method and assumptions
Monthly compounding with month-end additions. Nominal future rupees; does not assess retirement adequacy, future living costs, longevity, annuity income or tax.
Deposit rate comparison
Compare two cumulative deposits on equal terms.
Maturity at rate A: ₹1,19,562
Maturity at rate B: ₹1,23,144
B minus A before tax: ₹3,582
Method and assumptions
Both compound quarterly, before tax. Differences in liquidity, eligibility, penalties and insurance are outside this calculation. Rates are examples, not bank quotations.
Debt payoff
Estimate payoff time with a fixed monthly payment.
Months to repay: 24
Total paid: ₹1,19,783
Interest paid: ₹19,783
Method and assumptions
Monthly reducing balance, no new borrowing or fees. A payment no greater than monthly interest will not repay the debt. The final instalment may be smaller. Simulation limited to 600 months.
Understand the result before acting
An EMI estimate is not a loan sanction or a lender quote. Compare the lender’s repayment schedule, processing fees and floating-rate reset terms. A lower EMI can simply mean a longer loan and more total interest.
Deposit estimates are before income tax. RD results depend on when each instalment reaches the bank. Investment projections assume steady returns; actual investment values can fall. None of these tools predicts a credit score or guarantees a financial outcome.
Worked example: ₹5 lakh loan
At an assumed 9% annual interest over 60 months, the reducing-balance EMI is approximately ₹10,379. Total instalments are approximately ₹6,22,751, including ₹1,22,751 interest. The calculation uses unrounded instalments internally; a bank’s rounding can produce a small difference.
Deposit protection reference
DICGC combines eligible principal and interest held in the same right and capacity across branches of one insured bank for its ₹5 lakh limit. Read DICGC’s official guide and check whether the bank and deposits qualify.
