About FinanceTools

What We Do

FinanceTools is a free website offering practical financial calculators, health tools, and unit converters for everyday use. Every tool runs entirely in your browser — nothing is stored on a server, and you don't need an account to use anything.

We built FinanceTools because most online calculators are cluttered, inaccurate, or buried behind sign-up walls. Our tools cover the calculations Indians do most — income tax, loan EMIs, SIP returns, BMI, age, and 30+ unit conversions — all in one place, for free.

The goal has always been the same — give you an accurate answer in seconds and get out of the way.

Our Tools

• Income Tax Calculator

  Calculates your income tax liability for FY 2025-26 under both the New and Old tax regimes. Enter your income and deductions to compare your tax outgo under each regime and find out which saves you more.

• SIP Calculator

  Estimates the future value of your monthly SIP (Systematic Investment Plan) contributions using compound interest. Useful for planning mutual fund investments over 1 to 40 years.

• EMI Calculator

  Calculates the monthly EMI (Equated Monthly Instalment) for home loans, car loans, or personal loans. Shows total interest payable and a full amortisation breakdown.

• Age Calculator

  Enter a date of birth and a reference date (defaulting to today) to get an exact age breakdown — years, months, days, and the total number of days lived. It also shows when the next birthday falls.

• Unit Converters

  Over 30 individual converters covering length, weight, temperature, volume, speed, area, angle, and power. Each one has a live two-panel interface so you can type in either direction.

How We Handle Accuracy

We take the numbers seriously. Income tax calculations follow the official FY 2024-25 slabs and rebate rules published by the Income Tax Department of India, including the 4% Health and Education Cess and Section 87A rebate thresholds. EMI calculations use the standard reducing-balance formula. SIP projections use compounded monthly returns.

BMI formulas follow the NHLBI standard — 703 × weight(lb) ÷ height(in)² for imperial and weight(kg) ÷ height(m)² for metric. Unit conversion factors come from the International System of Units (SI).

If you spot a result that looks wrong, please contact us. We review every report and correct errors promptly.

A Note on Health Information

BMI is a screening tool, not a diagnosis. It tells you where your weight-to-height ratio sits relative to population averages, but it doesn't measure body fat directly and doesn't account for muscle mass, bone density, age, or sex. A single number from a calculator is never the full picture of someone's health.

If you have questions about your weight or health, talk to a doctor or registered dietitian. Our tools are here to give you a quick reference point, not a medical opinion.
