Calculate with confidence.

Designed to make numbers easier

Every ClearCalc tool focuses on one job, shows the formula it uses, and runs in your browser. Nothing you type is sent to a ClearCalc account. Results are estimates. For an important money or health decision, compare the result with a qualified professional and with the lender, school, or clinician who has your actual terms.

The mortgage payment calculator and the loan payment calculator both use standard monthly amortization, with taxes and fees left out so the interest math stays visible. The compound interest calculator projects a balance from a starting amount and end-of-month deposits. Health tools cover adult BMI from kilograms and centimeters and a maintenance-calorie estimate from the Mifflin–St Jeor equation for men or women. Everyday math includes a percentage calculator, a tip split, a percent-off sale price, and a length converter from meters to feet, inches, yards, or kilometers. Date tools count an exact age or the days between two dates. Work and pay includes a 2026/27 take-home pay calculator for employees in England, Wales, and Northern Ireland. The GPA calculator averages four unweighted grades on a 4.0 scale, and the final exam grade calculator solves for the score a weighted final needs. Home projects include a concrete slab calculator that turns feet and inches into bags and cubic yards.

Five later tools answer questions the earlier pages leave open. The 2026 New York paycheck calculator adds New York State tax and, when you ask for it, New York City resident tax. The Alberta take-home pay calculator uses the 2026 Alberta brackets, CPP, and EI, with no provincial health premium. The NSW stamp duty calculator applies 2026/27 New South Wales transfer duty, including the first home buyer concession. The UK student loan repayment calculator estimates a 2026/27 Plan 1, Plan 2, Plan 4, Plan 5, or postgraduate deduction, which the England take-home page does not subtract. The room paint calculator turns a rectangular room into gallons. The day counter still includes weekends: calendar year 2026 has 261 weekdays, 52 Saturdays, and 52 Sundays, and the elapsed count from 1 January to 31 December remains 364.

Pay calculators are split by the tax system they use. The Texas paycheck calculator and the Florida paycheck calculator estimate 2026 federal income tax, Social Security, and Medicare, with a state income tax line of zero. The California paycheck calculator adds 2026 California income tax and State Disability Insurance. The Washington paycheck calculator keeps state income tax at $0 and subtracts 2026 Paid Leave and WA Cares. The Scotland take-home pay calculator uses the 2026/27 Scottish income tax bands.

Another set of tools answers a narrower question than the page beside it. The 2026 Illinois paycheck calculator keeps the federal brackets and then applies the 4.95% Illinois rate after a $2,925 exemption, which is a different subtraction from the New York brackets or from a state line of zero. The Manitoba take-home pay calculator uses the 2026 Manitoba brackets, 10.8%, 12.75%, and 17.4%, with the $15,780 basic personal amount, on top of the same federal, CPP, and EI figures as Alberta. The Victoria stamp duty calculator applies Victorian land transfer duty, including the first home buyer concession through $750,000 and the 8% foreign purchaser additional duty. The US business days calculator counts inclusive weekdays and can remove the 11 federal holidays. For 2026 that leaves 250 business days, against 261 weekdays and against the 364 elapsed days from 1 January to 31 December on the day counter. The mulch calculator turns a bed measured in feet, and a depth in inches, into cubic yards and 2 or 3 cubic foot bags. A 10 by 20 foot bed at 3 inches is 25 of the 2 cubic foot bags, which is not the bag count on the concrete page.

Five more tools fill gaps those pages leave. The 2026 Pennsylvania paycheck calculator applies the 3.07% state tax to wages before a 401(k), then a local earned income tax rate you type and a flat local services tax.

Five further tools answer a different statute or a different unit. The 2026 Ohio paycheck calculator follows Ohio Revised Code 5747.02: no nonbusiness tax on the first $26,050 of Ohio taxable income, then $332 plus 2.75% of the excess, after a personal exemption.

The Scotland LBTT calculator applies residential Land and Buildings Transaction Tax, including first-time buyer relief of up to £600 and the 8% additional dwelling supplement. A £250,000 main home is £2,100, against £2,500 of SDLT on the England page. The Canada business days calculator removes statutory holidays for Ontario, British Columbia, or Alberta. Ontario has 253 business days in 2026, British Columbia 250, and Alberta 252, against 261 weekdays. The 5K pace calculator turns a finish time into minutes per kilometre and per mile. A 25:00 5K is 5:00 per kilometre and 8:02.8 per mile, which is not a calorie total.

Five further tools use a different statute or a different unit from the page beside them. The 2026 Michigan paycheck calculator applies 4.25% after a $5,900 exemption. At $65,000, single, with one exemption and no city tax, Michigan tax is $2,511.75 and the two-week headline is $1,995.99. Ohio on the same wages is $1,344.00 of state tax and $2,040.90 every two weeks. A Detroit resident on the Michigan wage adds $1,545.60 of city tax. The New Brunswick take-home pay calculator uses the 2026 brackets, 9.40%, 14%, 16%, and 19.5%, and a $13,664 basic personal amount.

The floor tile calculator counts tiles from a grout joint. A 10 by 12 foot floor with 12 inch tiles, a 1/8 inch joint, and 10% waste is 130 tiles, 13 boxes of 10. The fuel economy converter separates the US gallon from the imperial gallon. 30 US mpg is 7.84 L/100 km and 36.03 UK mpg. The same digits read as UK mpg are 9.42 L/100 km.

Five further tools use a statute or a measurement the pages above do not. The 2026 Georgia paycheck calculator applies the 4.99% rate in HB 463 after a $15,000 single standard deduction. At $65,000, single, with no dependents, Georgia tax is $2,495.00 and the two-week headline is $1,996.63. The North Carolina paycheck calculator uses the 3.99% rate for taxable years after 2025 and a $12,750 standard deduction. The same wage is $2,084.78 of North Carolina tax and $2,012.41 every two weeks. The Quebec take-home pay calculator uses QPP, QPIP, the 1.30% Quebec EI rate, and the 16.5% federal abatement. At $70,000 the monthly headline is $4,253.73, which is $83.09 below New Brunswick because the payroll system is not the same. The Western Australia stamp duty calculator uses the first home owner rate for an agreement entered into on or after 7 May 2026. A $650,000 home is $8,075.00, against $24,890.00 on the general rate.
