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.
