About the VAT Calculator

The VAT Calculator works out Value Added Tax in two directions: it adds VAT to a net (pre-tax) figure to give you the gross price a customer pays, or it strips VAT back out of a gross figure to reveal the net amount and the tax portion separately. You type in an amount, pick a rate, and choose whether the figure you entered already includes tax. That second choice matters more than people expect, because adding 20% and removing 20% are not the reverse of each other in plain arithmetic, and getting the direction wrong is the single most common VAT mistake.

Reach for this tool whenever a number and a tax rate collide. Freelancers use it to quote a client a clean gross price, retailers use it to back out the tax already baked into a shelf price, and bookkeepers use it to split a receipt total into net and VAT for their records. Because you can type any rate, it handles a 20% UK standard charge, a 5% reduced rate, a 0% zero-rated supply, or any of the EU rates from Luxembourg's 17% up to Hungary's 27%. The multi-currency selector simply changes the symbol shown; the maths is identical whatever currency you work in.

Under the hood the calculator uses the standard VAT formulas rather than a percentage shortcut. To add tax it multiplies the net amount by one plus the rate, so 500 at 20% becomes 500 x 1.20 = 600. To remove tax it divides the gross amount by that same factor, so 600 at 20% returns 600 / 1.20 = 500, leaving 100 of VAT. This is why you cannot simply subtract 20% from a gross price: that would take 20% of the larger, tax-inclusive figure and overshoot. The tool always shows you the net, the VAT amount, and the gross together so every component reconciles.

Everything runs in your browser. The amounts and rates you enter are never uploaded to a server, stored, or shared, which matters when you are checking real invoice or pricing figures. Results are rounded for display to two decimal places, the convention used on most invoices, so a long line of items may differ by a penny from a total that VAT was applied to in one lump. For filing a return or issuing a formal VAT invoice, treat this as a fast cross-check against your accounting software and confirm the current rate and rounding rules for your jurisdiction with the relevant tax authority.

Frequently asked questions

How do I add VAT to a price?

Enter the net amount, set the VAT rate, and choose the option that adds tax. The calculator multiplies the net figure by one plus the rate, so 500 at 20% gives 600 gross with 100 of VAT.

How do I remove VAT from a gross (VAT-inclusive) price?

Enter the gross amount and select remove or reverse VAT. The tool divides the figure by one plus the rate, so 600 at 20% returns a net of 500 and a VAT portion of 100. Do not simply subtract 20%, as that takes the percentage from the larger tax-inclusive total and gives the wrong answer.

What is the current standard UK VAT rate?

The UK standard rate is 20% and has been unchanged since January 2011. A reduced rate of 5% applies to items such as domestic energy, and some goods like most food and children's clothing are zero-rated at 0%. You can type whichever rate fits your situation.

What VAT rates apply in the EU?

Standard EU rates range from 17% in Luxembourg to 27% in Hungary, with most countries between 19% and 25%. Because the calculator accepts any rate, you can use it for any country; just enter that country's current standard or reduced rate.

Can I rely on these figures for my VAT return?

Use the calculator as a quick check rather than the final word. Results are rounded to two decimals, and totals built up line by line can differ slightly from VAT applied to a single total, so confirm the exact figures and rounding rules with your accounting software or tax authority before filing.

Time and a Half Explained: How Overtime Pay Is Really Calculated

By the Super Simple Digital Tools Team · Updated June 2026

Time and a half is one of those payroll phrases everyone has heard but few can define precisely. It simply means 1.5 times your normal hourly rate, so a worker earning $18 an hour is paid $27 for each overtime hour. The half is the premium your employer adds for hours worked beyond the normal threshold. The phrase says nothing about how many hours you have worked, only about the rate that kicks in once you cross into overtime territory.

In the United States, the trigger for that premium is the workweek. The Fair Labor Standards Act defines a workweek as a fixed, recurring period of 168 consecutive hours, and it requires at least time and a half for non-exempt employees on every hour past 40 in that week. Crucially, employers cannot average two weeks together to dodge the rule: 50 hours one week and 30 the next still owes 10 hours of overtime, not zero. The workweek does not have to match the calendar week, but it must stay consistent.

Calculating it yourself takes two steps. First, find your overtime rate by multiplying your regular rate by 1.5. Then multiply that overtime rate by the number of overtime hours. If you want your full paycheck for the week, add your regular pay for the first 40 hours to that overtime figure. For example, 40 hours at $20 is $800, plus 6 overtime hours at $30 is $180, giving $980 in gross pay for the week.

Salaried workers trip people up because there is no obvious hourly figure to start from. If you are salaried but non-exempt, you first convert the salary to an hourly regular rate by dividing your weekly salary by the hours that salary is intended to cover, then apply the 1.5 multiplier to that rate. A separate wrinkle is bonuses: nondiscretionary bonuses tied to performance or attendance have to be rolled into the regular rate before the multiplier, which nudges the overtime rate upward beyond the base wage alone.

Use this calculator as a quick, private check rather than a legal ruling. It assumes a straightforward 1.5 multiplier and the rate you supply, and it returns gross numbers before tax. State laws frequently go further than the federal floor, adding daily overtime or double time, and your employment contract may be more generous still. When the stakes are high, confirm against your pay stub, your state labor department, and your employer's written policy.

Enter your true regular rate, including any nondiscretionary bonus folded in, so the 1.5 multiplier reflects what the law actually requires.
Remember the 40-hour line is per workweek, not per pay period, so a biweekly check still owes overtime week by week.
Check whether your state mandates daily overtime or double time; the federal time-and-a-half rule is only the minimum.
Treat the result as gross pay and subtract your usual tax and deduction percentage to estimate real take-home before payday.
