Profit, Break-Even and Growth Calculators

Break-Even, ROAS, EBITDA, Churn, LTV, CAC and MRR to ARR Calculators

Once the work is under way, is it actually working? These calculators answer the questions that decide that: how many units before the fixed costs are covered, what advertising return you need just to stand still, what a customer is worth over their lifetime, and how many months of cash are left at the current burn.

Every Profit & Growth tool

Break-Even Calculator

Units and revenue needed to cover fixed costs, and to hit a profit target.

Break-Even ROAS Calculator

The ROAS multiple at which an ad campaign stops losing money.

Free Shipping Threshold Calculator

The order value at which free shipping still makes money.

Rent Per Square Foot Calculator

Convert commercial rent into cost per square foot and per person.

Runway Calculator

Months of cash left from balance, burn and revenue growth.

Wholesale Price Calculator

Wholesale price and recommended retail price from cost and margins.

Break-even

The break-even calculator divides fixed costs by the contribution each unit makes — price minus variable cost — to give the number of sales at which you stop losing money. It also shows the revenue at that point and, if you enter a target profit, the volume needed to reach it. The break-even ROAS calculator applies the same logic to advertising: given your margin, it gives the return on ad spend below which every sale from a campaign costs more than it earns.

Margin, markup and discounts

Margin versus markup is one calculator because the confusion between them is one problem: a 25% markup is a 20% margin, and pricing by one while reporting by the other is how profit vanishes. The double-discount calculator shows why "20% off, then a further 15% off" is not 35% off, and the free-shipping threshold calculator finds the order value at which absorbing delivery cost still leaves your target margin intact.

Property

Lease per square foot converts a quoted rent into a comparable figure across spaces of different sizes and payment periods, and back into a monthly cash cost, so two premises can be compared like for like.

Subscription businesses

Customer lifetime value multiplies average revenue per customer by margin and expected lifetime, which the calculator derives from churn. SaaS CAC divides sales and marketing spend by customers acquired and compares it with LTV — a ratio under three-to-one is the usual warning sign. MRR to ARR annualises monthly recurring revenue and shows the effect of growth and churn month by month. Churn rate converts monthly losses into an annual rate and an average customer lifetime. Runway divides cash on hand by net monthly burn and gives a date, not just a number of months. The SaaS spend audit lists every subscription your business pays for, annualises the total and shows which ones cost the most per seat.

Revenue, ads and conversion

The revenue calculator takes discounts and returns off gross sales to give the net figure worth tracking, and the wholesale price calculator sets a trade price and a recommended retail price from your cost and both parties' margins. ROAS divides ad revenue by ad spend and checks it against your break-even point, the conversion rate calculator turns visitors into sales and revenue per visitor, and EBITDA adds interest, tax, depreciation and amortisation from your own accounts back to net profit.

Estimates you can argue with

Every result shows its formula and inputs, because these are the numbers that end up in a board deck or a bank conversation, and you will need to defend them. Nothing you enter is sent to a server; all of it runs in your browser.
