You enter a start point, end point, travel mode, and (optionally) fuel details; the calculator then returns distance, time, cost, and carbon footprint. A typical U.S. car emits 0.21 kg CO₂ per kilometre (EPA, 2023).
Estimate your borrowing power in seconds: the calculator shows that homeowners can usually access up to 85 % of their home’s value minus existing liens (CFPB, 2023). Enter property value, mortgage balance, and rate; the tool instantly returns maximum line size, monthly draw-period interest, amortized repayment, and lifetime cost—helping you budget renovations or consolidations with confidence.
Estimate your bench-press 1RM without performing a dangerous max attempt. Enter any working set (up to 20 reps) and the calculator returns four science-based predictions. Most lifters can predict their bench-press 1RM within ±10 % using sub-maximal reps (Mayhew et al., 1995).
Use beginning retained earnings, add net income, subtract dividends, adjust for corrections to get ending retained earnings. A $1 million firm in the S&P 500 retained about 65 % of profits in 2023 (Statista, 2024).
Real GDP strips out inflation: divide Nominal GDP by the GDP Deflator/100. With the U.S. deflator at 125.7 in 2023, every $1 trillion of nominal output equals about $795 billion in real terms (BEA, 2024). Use the tool below to run your own numbers quickly.
A margin-of-error tells you how far your sample result can stray from the real population value. Plug in sample size, deviation or proportion, and a confidence level—the calculator returns the ± error and a full confidence interval. Larger samples shrink the error: at n = 1 000 and p = 0.5 the 95 % MOE ≈ ±3.1 % (U.S. Census Bureau, 2022).
Your acceleration equals change in velocity divided by time, or net force divided by mass. Enter any method, tap “Calculate,” and the tool returns the value in m/s²—no manual math. Earth’s gravity adds 9.806 65 m/s² to every free-falling object (BIPM, 2019).
This calculator shows how your income splits into expenses, savings and leftover cash in seconds. U.S. households saved only 4.1 % of disposable income in 2023 (FRED https://fred.stlouisfed.org/series/PSAVERT), so a clear monthly snapshot helps you beat that average.
Convert any birth date into its Chinese zodiac animal in seconds: the script subtracts 1900, applies $$bmod,12$$, and adjusts for Lunar New Year. The zodiac cycle repeats every 12 years (ChinaCulture.org).
