Finance & Loans
Borrowing is arithmetic that runs for decades, which is why small differences in rate or tenure end up being large differences in money. These tools show the whole schedule rather than the monthly figure alone. The split between interest and principal is usually the part that changes a decision.
Loans
EMI CalculatorWork out the EMI on any loan, see the full month-by-month schedule, and find out how much of your money goes to interest rather than to the debt.Reverse EMI CalculatorStart from the EMI you can afford and work backwards to the loan it supports. This is the question most borrowers actually have, and most calculators make you guess at it.Loan Tenure CalculatorHow long a loan takes to clear at a given payment. If the payment does not cover the first month's interest, the tool says so rather than returning an impossible number.Loan Interest Rate CalculatorRecover the interest rate a lender is actually charging from the loan amount, the EMI and the term. Useful when a quote gives you a payment but is vague about the rate.Loan Prepayment CalculatorWhat a lump-sum prepayment actually buys you, and which of the two options (keep the EMI and shorten the tenure, or keep the tenure and cut the EMI) saves more.Loan Amortization ScheduleThe full amortisation schedule for a loan. Every instalment split into interest and principal, with the running balance and a downloadable table.Loan Eligibility CalculatorHow much a lender will advance, working backwards from the payment your income supports. The tenure does most of the work, and stretching it buys a larger loan at a large cost in interest.Personal Loan EMI CalculatorEMI on an unsecured personal loan. Rates run well above secured lending, so the total interest on even a short term is substantial, the schedule below shows how much.Student Loan Repayment CalculatorStudent loan repayment with the grace period modelled. On an unsubsidised loan interest accrues through the grace period and is capitalised, so the balance you start repaying is larger than the amount you borrowed.Student Loan Refinance CalculatorStudent loan refinancing saving. Refinancing a federal loan with a private lender permanently forfeits income-driven repayment, forgiveness eligibility and the deferment protections, and that decision cannot be reversed.Income-Driven Repayment CalculatorIncome-driven repayment with the forgiveness outcome. Where the payment is below the monthly interest the balance grows despite paying, which is the feature people find hardest to accept and which forgiveness is designed to resolve.PSLF Forgiveness CalculatorPublic service loan forgiveness projection. The requirement is 120 qualifying payments, not ten years: a period in the wrong plan or the wrong employment does not count and does not reset, it simply does not accrue.Business Loan EMI CalculatorEMI on a term business loan, with the schedule you need for a cash-flow projection rather than just the monthly figure.Working Capital Loan CalculatorEMI on a working-capital term loan. Short tenures at commercial rates. The schedule matters more than the monthly figure when you are matching it to a receivables cycle.APR CalculatorThe APR is the rate that makes the money you actually receive equal the payments you actually make. Fees deducted up front raise it above the quoted rate, sometimes considerably.Effective Annual Rate CalculatorThe one number that makes two differently-compounded rates comparable. This is the whole content of the APR-versus-APY question.Extra Payment CalculatorWhat paying a little more each month actually buys you. On a 20-year home loan an extra ₹5,000 clears it more than four years early and saves close to ₹14 lakh in interest.Interest-Only Loan CalculatorAn interest-only loan and the payment jump when principal starts. The balance does not fall by a rupee during the interest-only period, which is the whole risk.Balloon Payment CalculatorThe lump sum due at the end of a balloon loan. Payments are set as if the loan ran much longer, so most of the principal is still outstanding when it falls due.
Mortgage
Mortgage Calculator (PITI)The full monthly payment on a mortgage: principal and interest, plus the property tax, insurance and dues your lender collects with them. With the amortisation schedule and the total interest across the life of the loan.Mortgage Affordability CalculatorThe house price two lending ratios allow, and which of them binds. The front-end ratio caps housing alone and the back-end caps all debt, and someone with car and student loans is usually limited by the second.PMI CalculatorPrivate mortgage insurance cost and when it cancels. PMI protects the lender, not you, and it must be terminated automatically at 78 percent loan to value, though you can request it at 80.Mortgage Points & Buydown CalculatorWhether buying mortgage points pays. A point costs one percent of the loan and typically buys a quarter point of rate, so break-even usually falls between four and seven years, which is longer than most people keep a mortgage.Mortgage Payoff CalculatorWhat paying extra does to a loan. Every extra dollar goes entirely to principal, so the effective return on paying early is the loan rate itself, guaranteed and risk free.ARM vs Fixed Rate CalculatorARM against fixed rate, judged on the capped worst case rather than the teaser rate. The question is not whether the initial saving is real but whether you can afford the payment if rates hit the lifetime cap.15 vs 30 Year Mortgage CalculatorFifteen against thirty years, comparing the interest saved to what the payment difference would earn invested. The shorter loan always costs less interest and is not automatically the better decision.Refinance Break-even CalculatorWhether refinancing pays, on both the monthly saving and the lifetime interest. Extending the term while lowering the rate can cut the payment and raise the total cost, which is the trap this makes visible.Cash-Out Refinance CalculatorCash-out refinance cost. Refinancing a low rate to take cash out reprices the entire balance at the new rate, which is why the cash can cost far more than its face value in extra interest.HELOC Payment CalculatorPayment on a home equity line once it enters the repayment phase, amortising the drawn balance over the remaining term.Rent vs Buy CalculatorRent against buy over the years you will actually stay, comparing net worth rather than monthly outgo. The honest comparison invests the down payment and every monthly difference, which is the step most versions of this skip.Mortgage Interest Deduction CalculatorThe real tax benefit of mortgage interest. Only the amount by which itemised deductions exceed the standard deduction saves anything, so the benefit is far smaller than the interest times the tax rate.Bi-weekly Payment Savings CalculatorWhat paying half your mortgage payment every two weeks actually saves. Twenty-six half-payments a year is thirteen monthly payments, and that thirteenth one is what retires the loan years early.
Auto
Car Loan EMI CalculatorEMI on a car loan, with the schedule and the total interest. Vehicle loans are short and front-loaded, so the interest share is smaller than a mortgage but the rate is usually higher.Auto Lease Payment CalculatorLease payment broken into depreciation, finance and tax. A money factor multiplied by 2,400 gives the equivalent APR, which is the only way to compare a lease against a loan.Lease vs Buy a Car CalculatorLeasing against buying over the lease term, comparing net cost after the car you still own. A lease payment is always lower than a loan payment, which is why comparing monthly figures answers the wrong question.Car Affordability CalculatorWhat car a payment supports, with running costs shown alongside. Fuel, insurance, tax and servicing typically add most of the loan payment again, which is the part the showroom conversation leaves out.
Credit
Credit Card Interest CalculatorHow long a card balance takes to clear and what it costs, with the effective annual rate spelled out. A 3.5% monthly rate is not 42% a year, it is over 51%.Credit Card Minimum Payment PayoffHow long a card balance takes to clear and what a target date would cost. The first month of interest is shown, because a payment below it means the balance never falls at all.Credit Card Balance Transfer CalculatorBalance transfer saving after the fee. A transfer only pays if you clear a large share of the balance during the promotional period, because the fee is charged immediately and the post-promotional rate is usually no better than the original.
Debt
Debt Snowball CalculatorThe snowball: clear the smallest balance first, then roll its payment into the next. It costs more interest than the avalanche and it works, because finishing a debt is what keeps people going.Debt Avalanche CalculatorThe avalanche: clear the highest rate first, then roll its payment into the next. It is mathematically optimal and always costs the least interest of any ordering.Debt Consolidation CalculatorDebt consolidation with the term effect separated from the rate effect. A lower monthly payment can come from a lower rate or from a longer term, and only the first saves money.Debt-to-Income Ratio CalculatorDebt to income on both ratios lenders actually use. The front end covers housing alone and the back end covers all debt, with different limits, so a borrower who clears the ratio they know about can still fail the one they do not.
Interest
Simple Interest CalculatorSimple interest, with the compound equivalent shown next to it. The gap between the two is the entire argument for starting early.Compound Interest CalculatorCompound interest at any frequency, including continuous, with optional monthly additions and the effective annual rate. The only figure that lets you compare two different compounding frequencies honestly.Daily Compound Interest CalculatorDaily compounding over any number of days, with the gain over annual compounding shown. The difference is smaller than most people expect and it is the reason continuous compounding is a limit rather than a leap.Continuous Compounding CalculatorContinuous compounding, and the surprisingly small amount it adds over compounding once a year. It is the mathematical ceiling on frequency, not a different kind of growth.Rule of 72 CalculatorExact doubling time next to the Rule of 72 and the Rule of 70, so you can see where each approximation is good and where it drifts.Money Doubling Time CalculatorHow long money takes to double, triple or reach any multiple at a given rate. The general form of the Rule of 72.
Deposits
Certificate of Deposit (CD) CalculatorCertificate of deposit maturity value, with the distinction between the quoted yield and the nominal rate behind it. APY already includes compounding, which is why it is the only figure worth comparing.CD Ladder CalculatorA deposit ladder against a single long deposit. The ladder gives up part of the term premium and buys regular access, which is a liquidity purchase rather than a return strategy.
Bonds
Series I Bond CalculatorUS Series I savings bond value. The composite rate is not the fixed rate plus inflation: the official formula includes a cross term, and the fixed rate is locked for the life of the bond.Treasury Bill Yield CalculatorThe three yields a Treasury bill can be quoted at, and why they differ. The discount yield on a dealer screen is always the lowest of them, and it is not the return on your money.Bond Price CalculatorThe price of a bond from its required yield. Price and yield move opposite ways, and a bond only trades at face value when the two rates are equal.Bond Yield to Maturity CalculatorYield to maturity from a price, solved rather than approximated. It is the only yield measure that counts both the coupons and the pull to par, which is why it differs from current yield on any bond not trading at face.Current Yield CalculatorCurrent yield and an approximate yield to maturity. Current yield ignores the capital gain or loss at redemption, which is why a discount bond always shows a YTM above its current yield.Bond Duration CalculatorHow far a bond price moves when yields move. Duration is the number traders actually quote, because it converts a yield change into a price change in one multiplication.Zero Coupon Bond CalculatorA bond that pays nothing until it matures, priced as a single discounted payment. With no coupons to reinvest, the quoted yield is the return you actually get.Accrued Interest CalculatorAccrued interest between coupon dates, across day count conventions. The convention is not a detail: actual/360 and 30/360 give materially different answers on the same bond.
More
APY CalculatorAPR to APY. Savings products quote APY and loans quote APR, and comparing the two directly is comparing different things.High-Yield Savings Growth CalculatorSavings account growth with the real return stated. A savings rate below inflation means the balance grows nominally and shrinks in what it can buy, which is the usual case.Savings Goal CalculatorThe monthly amount that reaches a savings target, with what your existing balance contributes on its own. Over short horizons growth does very little and the contribution is nearly the whole answer.Emergency Fund CalculatorHow large an emergency fund needs to be and how long it takes to build. Sized on essential spending rather than total spending, which is the distinction that matters.Money Market Yield CalculatorMoney market yield across conventions. Discount yield divides by face value and uses a 360 day year, so the same instrument quotes lower on that basis than on a bond equivalent basis.
