Calculate Loan EMIs, SIP Returns, and Tax Liability Without Spreadsheets

How These Calculators Work

Each calculator accepts inputs specific to its financial instrument and applies the governing formula to produce an instant result. The EMI calculator uses the standard reducing-balance amortisation method. The SIP calculator compounds monthly at your entered annual rate and shows corpus growth across any tenure.

The compound interest calculator separates principal from interest earned and supports daily, monthly, quarterly, and annual compounding frequencies. The GST calculator converts between tax-exclusive and tax-inclusive prices for all current slabs. Inputs update the output in real time as you type.

Which Calculator Matches Your Decision

Use the loan EMI calculator when evaluating a home loan, car loan, or personal loan offer. Use the loan eligibility calculator to understand the maximum principal a lender would sanction against your income and existing financial obligations.

The income tax calculator compares old and new regime liabilities for your declared income and displays net payable tax after applicable deductions. The capital gains tax calculator applies short-term and long-term rates to asset sale profits across equity, debt, and real estate categories.

The retirement savings calculator determines whether your current savings rate reaches your target corpus by your planned retirement age. The ROI calculator converts any gain and cost pair into a percentage return. All calculations run entirely in your browser and no data is transmitted or stored.

Reducing Balance Interest vs Flat Rate Interest

Two loan pricing methods exist in Indian lending: the reducing balance method and the flat rate method. Under the reducing balance method, interest is charged only on the outstanding principal remaining after each payment, which means the interest portion of your EMI shrinks every month as the loan balance falls.

Under the flat rate method, interest is calculated on the entire original principal for every month of the tenure, regardless of how much principal you have already repaid. A flat rate of 10 percent per year is not equivalent to a 10 percent reducing balance rate. The effective annual rate on a flat rate loan is approximately 1.8 to 1.9 times the stated flat rate, making a 10 percent flat loan equivalent to roughly 18 percent on a reducing balance basis.

All home loans and most personal loans from scheduled banks in India use the reducing balance method, as mandated by RBI disclosure norms. Certain consumer finance NBFCs and vehicle dealers still quote flat rates in their promotional materials. Run both scenarios in this EMI calculator before accepting any loan offer to verify the true cost.

How a Half-Percent Rate Change Affects Your Loan

On a home loan of 50 lakh rupees over 20 years, the difference between an 8.5 percent and a 9 percent interest rate is approximately 1,700 rupees per month in EMI. Over the full tenure, that 0.5 percent difference adds up to over 4 lakh rupees in total interest paid.

Rate sensitivity increases with loan size and tenure. A 1 crore home loan over 30 years at 9 percent generates total interest of approximately 1.67 crore rupees, meaning you pay more than two and a half times the borrowed amount in total. Reducing the rate to 8.5 percent on the same loan saves approximately 10 lakh rupees in total interest.

This is why floating rate loans linked to the repo rate or MCLR can change your financial outcome substantially when RBI revises the policy rate. Use the EMI calculator to recompute your monthly obligation immediately after any rate revision notice from your lender.

Old Tax Regime vs New Tax Regime: When Each Wins

From FY 2024-25 onward, the new tax regime became the default for all taxpayers in India. Taxpayers who wish to claim deductions under Section 80C, 80D, and house rent allowance exemptions must actively opt into the old regime before filing. The new regime offers lower slab rates but eliminates most deductions.

The old regime typically benefits taxpayers who have large Section 80C investments, home loan interest deductions under Section 24b, and HRA exemptions that together reduce taxable income by 2 lakh rupees or more. Salaried employees claiming the standard deduction of 75,000 rupees plus 80C investments of 1.5 lakh rupees plus home loan interest of 2 lakh rupees can reduce taxable income by 4.25 lakh rupees under the old regime.

The new regime benefits taxpayers without large deductions, those with primarily salary income and no home loan, and those earning above 15 lakh rupees where the new slab rates produce a lower tax liability even without deductions. Enter your income and planned investments into the income tax calculator to identify which regime produces the lower liability for your specific situation.

SIP Returns vs Fixed Deposit Returns: Setting Realistic Expectations

A systematic investment plan in a mutual fund is not a guaranteed return instrument. SIP returns depend on the fund category, the market conditions during the investment period, and when the investor exits. Equity mutual funds have historically returned 10 to 14 percent CAGR over 10-year periods in India, but individual years can produce negative returns.

Fixed deposits from scheduled banks are guaranteed instruments. The interest rate is fixed at the time of deposit and does not change regardless of RBI policy movements or market conditions. FD rates in India have ranged from 5.5 to 7.5 percent for tenures of one to three years over the past decade, with post-tax returns lower because FD interest is fully taxable as income in the year it is credited.

Long-term equity capital gains above 1.25 lakh rupees per financial year are taxed at 12.5 percent from FY 2024-25 onward. When comparing SIP and FD outcomes over the same tenure, apply the relevant tax rate to both instruments before comparing net returns. Use the SIP calculator for corpus projection and the income tax calculator for post-tax comparison.
