Open calculatorVAT & Sales Tax Calculator
Add or remove tax
Add VAT, GST or US sales tax to a net price, or work backwards from a gross figure to see the amount before tax. Includes preset rates for the UK, Ireland, US, Canada, Australia, New Zealand and major EU countries, plus any custom rate you need.
Open calculatorFreelancer & Agency Rate Calculator
Find your minimum rate
Work out the minimum hourly rate, day rate and monthly retainer you need to charge to hit your target income — after holidays, public holidays, sick days, non-billable admin, business expenses, pension contributions and a sensible profit margin. Built for accountants, designers, developers, marketers, copywriters, consultants and small agencies.
Open calculatorSEO ROI Calculator
Model ranking gains
Estimate the extra visitors, leads and revenue that improved Google rankings could generate for a target keyword. Uses editable industry-average click-through rates by position, your own conversion rate and either average customer value or lifetime value. Educational modelling rather than a guarantee.
Open calculatorBreak-even Calculator
How many customers do I need?
Work out how many customers, subscriptions or units you need to sell each month before the business covers its costs — and how many more it takes to reach a profit target. Uses fixed costs, price per sale and variable cost per sale to show your contribution margin, break-even volume and the revenue that goes with it.
Open calculatorCAC Calculator
Customer acquisition cost
Add up advertising, salaries, software and agency fees for the month, divide by the customers you actually won, and see your true customer acquisition cost. Includes a paid-only CAC, the LTV to CAC ratio and a payback period so you can tell quickly whether growth is paying for itself.
Open calculatorLTV Calculator
Customer lifetime value
Estimate what a customer is worth across the whole relationship, using average order value, purchase frequency, gross margin and monthly churn. Shows lifetime revenue, gross-profit lifetime value, average customer lifespan and the maximum you can sensibly spend to acquire one.
Open calculatorProfit Margin Calculator
Gross, net and markup
Gross margin, net margin and markup side by side, worked out from your selling price, direct costs and allocated overheads. Margin is profit as a share of the price; markup is profit as a share of the cost — confusing the two is one of the quickest ways to underprice a job.
Open calculatorPricing Calculator
How much should I charge?
Build a price up from what the work actually costs: direct costs, the hours you put in at your hourly cost, the margin you want and the payment or platform fees that come off the top. Includes a good/better/best tier suggestion and shows exactly how much profit a discount takes away.
Open calculatorAffiliate Revenue Calculator
Project affiliate income
Model what a page, newsletter or whole site could earn from affiliate partnerships. Enter monthly visitors, click-through rate to the partner, partner conversion rate and your commission — percentage, flat bounty or recurring SaaS payout — to see projected monthly income, earnings per click, revenue per thousand visitors and a twelve-month projection with traffic growth.
Open calculatorCompound Interest Calculator
Watch growth compound
See what a starting pot plus regular monthly contributions could become once interest starts earning interest. Choose the rate, timeframe and compounding frequency — annually, quarterly, monthly or daily — and add an inflation rate and the chart plots three lines: the money you paid in, the nominal balance, and what that balance is really worth in today's money.
