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.

Cancel common letters pairwise from both names → count remaining letters → eliminate F-L-A-M-E-S circularly until one letter remains
Enter your name and your partner's (or crush's) name. We cross out matching letters from both names, count what's left, then eliminate FLAMES letters in a circle until one remains — F Friends, L Lovers, A Affectionate, M Marriage, E Enemies, S Siblings.
Open calculator →Flat: interest = P × rate × years; reducing: standard EMI amortization on outstanding balance each month
Enter loan principal, annual interest rate, and tenure. Flat rate applies interest on full principal for entire tenure; reducing balance charges interest only on outstanding principal each month.
Open calculator →result = input × (factor_from ÷ factor_to) relative to the SI base unit for this type
Flow rate converts through litres per second. Useful for plumbing, HVAC, and pump sizing.
Open calculator →Hourly rate = (Desired annual income + expenses + tax buffer) / billable hours per year
Enter desired annual take-home income, billable hours per week, estimated tax rate, and business expense percentage to find your required hourly billing rate.
Open calculator →FV = PV × (1 + r)^n + PMT × [((1 + r)^n − 1) / r]
Future Value combines compound growth on your initial amount plus future value of periodic contributions.
Open calculator →MPG = miles ÷ gallons; L/100km = (litres ÷ km) × 100; km/L = km ÷ litres
Enter distance travelled and fuel consumed. Metric mode (default) shows L/100 km and km/L; switch to imperial for MPG — with cross-conversions either way.
Open calculator →Net weight = gross × (1 − stone%); gold value = net weight × rate/gram; max loan = value × 75% (RBI norm). Repayment: EMI (reducing balance), interest-only (principal at maturity), or compound (unpaid interest capitalizes monthly)
Enter gross gold weight and stone deduction, pick purity, then set the lender's gold rate per gram and your gold loan interest rate. We value the ornament, apply the 75% loan cap, and calculate reducing-balance EMI for your tenure.
Open calculator →GPA = Σ(grade × credits) ÷ Σ(credits)
Enter each course grade (typically 0–4) and credit hours. GPA = sum(grade × credits) ÷ sum(credits).
Open calculator →Final grade = Σ(score × weight) ÷ Σ(weight)
Add each assignment score (0–100) and its weight (%). Final grade = weighted average of all components.
Open calculator →Gratuity = (15 × last drawn salary × years of service) / 26 under the Payment of Gratuity Act
Enter last drawn salary (basic + DA) and completed years of service. Gratuity = (15 × last drawn salary × years of service) / 26 under the standard formula.
Open calculator →GST amount = Base price × GST rate / 100; Total = Base + GST (or reverse: Base = Total / (1 + rate/100))
Select exclusive (tax added on top) or inclusive (tax included in price) mode, enter amount and GST rate to get base amount, GST, and total.
Open calculator →EMI = P × r × (1 + r)^n / ((1 + r)^n − 1); total interest = (EMI × n) − P
Enter property loan amount, interest rate, and repayment period to get monthly EMI, total payment, and interest breakdown.
Open calculator →Deduction = min(interest paid, ₹2L Section 24b cap) + min(principal repaid, ₹1.5L Section 80C cap)
Enter annual home loan interest and principal repaid. Section 24(b) allows up to ₹2 lakh interest deduction for self-occupied property. Principal counts under Section 80C (₹1.5L cap shared with PPF, ELSS, etc.).
Open calculator →Annual salary = Hourly rate × hours per week × weeks per year
Switch between salary-to-hourly and hourly-to-salary modes. Enter amount and hours per week to convert between annual, monthly, and hourly pay.
Open calculator →Worked minutes = end − start − break (if end ≤ start, add 24h); decimal hours = minutes ÷ 60
Enter shift start and end in HH:MM, optionally deduct unpaid break minutes. Overnight shifts (end before start) count into the next day.
Open calculator →Exempt HRA = minimum of (HRA received, Rent paid − 10% of Basic, 50%/40% of Basic for metro/non-metro)
Exempt HRA is the minimum of: (1) actual HRA received, (2) rent paid minus 10% of basic, (3) 50% of basic for metro or 40% for non-metro. Applicable under old tax regime only.
Open calculator →Tax = progressive slab tax on taxable income − rebates + surcharges; taxable income = gross − deductions
Enter annual income and deductions. Choose flat tax rate or progressive brackets to estimate total tax, effective rate, and monthly net income.
Open calculator →Tax = slab-wise tax − Section 87A rebate + 4% cess; old vs new regime use different slabs and deductions
Enter gross annual salary and deductions available under the old regime. We apply FY 2024-25 slabs, standard deduction (₹50k old / ₹75k new), Section 87A rebate, and 4% cess to show which regime leaves more in your pocket.
Open calculator →Future value = Present value × (1 + inflation rate)^years; purchasing power erodes as prices rise
Enter current amount, inflation rate, and number of years to see future value equivalent and purchasing power loss.
Open calculator →FV = P₀ × (1 + r)^t + PMT × [((1 + r)^t − 1) / r], combining initial amount and monthly contributions
Enter starting amount, monthly contribution, expected return, and time horizon to project future portfolio value.
