How beMyCalc builds, tests, and documents all 123 calculators — formulas, data sources, and assumptions.

When you move a slider or type an amount, the math runs locally in your browser. We do not send loan balances, salaries, or investment amounts to our servers. Share links encode your inputs in the URL so you can bookmark or send a scenario — treat shared URLs like any link that contains personal numbers.
Most tools use widely published financial math: reducing-balance EMI amortization, compound interest, SIP future value, CAGR, present/future value, and similar textbook formulas. Below you'll find every calculator with its formula and a link to the live tool. Each calculator page also has a "How we calculate" panel with the same equation.
India income tax, HRA, and regime-compare tools use slab rates and deductions documented for FY 2024-25 (AY 2025-26). PPF, NPS, SSY, NSC, and similar scheme calculators let you enter the notified interest rate — we do not hard-code a single live government rate unless the tool explicitly states one as a default example.
Scheme limits (80C cap, PPF yearly maximum, etc.) follow commonly cited rules at the time of the last review. Indian rules change in Union Budgets and notifications — always confirm with the Income Tax portal, EPFO, or your chartered accountant before filing or investing.
The currency converter fetches indicative mid-market rates from the Frankfurter API (European Central Bank reference data), cached for about an hour. Banks and card networks apply their own spreads and fees — use the exchange calculator to model fees separately.
Calculator pages show sample scenarios (e.g. ₹10L loan at 8.5% for 20 years). These are illustrations to explain the tool, not recommendations. Guides on /guides link to calculators so you can replace example numbers with your own.

A = P × (1 + r/n)^(n×t), where P = principal, r = annual rate, n = compounding periods per year, t = years
Enter principal amount, annual interest rate, compounding frequency, and time period to calculate final amount and interest earned.
Open calculator →Volume = length × width × depth; cubic yards = cubic feet ÷ 27
Enter length, width, and depth. Volume = L × W × D. We show cubic feet, cubic yards (÷27), cubic metres, and approximate 80 lb bag count.
Open calculator →Each month: interest = balance × APR/12; payment goes to interest first, then principal reduction
Enter balance, APR, and monthly payment to see months until payoff and total interest cost.
Open calculator →Card path: monthly interest on balance then payment applied; PL path: fixed EMI amortization over the loan tenure
Enter card balance, APR, and your current monthly payment vs a personal loan rate and tenure. We compare total interest and time to become debt-free.
Open calculator →Profit = (Sell price − Buy price) × Quantity; Return % = Profit / Cost × 100
Profit = (Sell Price − Buy Price) × Quantity. Works for any cryptocurrency.
Open calculator →Converted amount = Amount × exchange rate (mid-market rate from live data feed)
Select currencies and enter amount. Rates are fetched from live market data and updated regularly.
Open calculator →Net received = (Amount × rate) − fees; effective rate = net received / amount sent
Enter amount, exchange rate, and fee percentage to see net amount received after conversion costs.
Open calculator →Difference: calendar span from start to end (years, months, days with borrowing). Add: shift start date by days, weeks, months, or years
Pick two dates to see the calendar span in years, months, days, and total days — or start from one date and add/subtract a duration.
Open calculator →Avalanche/snowball: apply extra payment to target debt; recalculate interest monthly on remaining balances
Enter debt balance, interest rate, minimum payment, and optional extra payment to compare payoff timelines.
Open calculator →result = input × (factor_from ÷ factor_to) relative to the SI base unit for this type
Density converts via kg/m³. 1 g/cm³ = 1,000 kg/m³. Water is roughly 1 g/mL or 1,000 kg/m³.
Open calculator →Each die tumbles visually, then lands on 1 + floor(random × sides); total = sum of faces
Defaults to 1d6. Choose how many dice and sides, then tap Roll — dice tumble on the table and land showing pip (dot) faces with a running total.
Open calculator →result = input × (1024^from ÷ 1024^to) using binary byte factors
Uses binary prefixes: 1 KB = 1,024 B, 1 MB = 1,024 KB, and so on — the usual convention for memory and most OS-reported file sizes. Drive packaging sometimes uses decimal (1,000) GB instead.
Open calculator →Annual dividend income = Shares × dividend per share × payments per year
Dividend Income = Shares × Dividend Per Share × Payments Per Year.
Open calculator →Down payment = Home price × down payment %; Loan amount = Home price − Down payment
Down Payment = Home Price × Down Payment %. Loan Amount = Home Price − Down Payment.
Open calculator →Target fund = Monthly expenses × months of coverage (typically 3–6)
Multiply monthly expenses by number of months (typically 3-6) to get your emergency fund target.
Open calculator →EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P = principal, r = monthly rate, n = tenure in months
Input loan amount, annual interest rate, and tenure in months or years. EMI is calculated using the standard reducing balance formula.
Open calculator →result = input × (factor_from ÷ factor_to) relative to the SI base unit for this type
Energy converts through joules. 1 kWh = 3.6 MJ, 1 kcal = 4,184 J, 1 BTU ≈ 1,055 J.
Open calculator →Monthly employee + employer PF contributions compounded at EPF rate: FV = SIP formula on combined monthly deposit
Enter your monthly employee PF contribution, employer match (%), expected EPF rate, and years of service. Corpus is projected using monthly compounding on combined contributions.
Open calculator →FIRE number = annual expenses × 25; years to FIRE from savings rate and expected investment return
Based on the 4% rule: FIRE number = annual expenses × 25. Enter savings rate to estimate years to FIRE.
Open calculator →Maturity = P × (1 + r/n)^(n×t) for compounded FD; simple FD uses A = P × (1 + r × t)
Enter deposit amount, annual interest rate, and tenure. FD interest is typically compounded quarterly in India.
