Small Business Calculators
These calculators answer the money questions that come up every week when you run a small business or a sales team. Start with price: the markup calculator takes your cost and any one of markup, selling price or margin and fills in the other two, so you can see both percentages side by side and never confuse them. Then find how many units and how much revenue cover your fixed costs each month, with an optional profit target and a daily sales goal.
Before you borrow, the business loan calculator shows the monthly payment, total interest and how much an origination fee takes out of the money you actually receive. The sales commission calculator handles flat-rate plans, a higher rate above quota and tiered rates, and adds base salary for total pay. Customer lifetime value compares what a customer is worth with what it costs to win one, and inventory turnover shows how many days of stock you hold against typical ranges for your industry. Everything is calculated in your browser, and your prices, costs and sales figures are not sent to us.

Pricing, markup and break-even
Turn a cost into a selling price at the markup or margin you want, then see the units and revenue needed to break even and to reach a monthly profit target. For margins across a whole business, use the profit margin calculator.
Business loan payments
Enter the loan amount, rate, term and origination fee to see the monthly payment, total interest, total cost and net proceeds for a fixed-rate term loan such as an SBA or bank loan.
Sales commission and pay
Work out commission for a pay period under a flat rate, a quota with an accelerator rate above it, or three tiers, and see total pay with base salary and the effective commission rate.
Customer value and inventory
Estimate customer lifetime value from order size, purchase frequency, margin and retention, with the CLV to acquisition cost ratio and payback period, and measure how fast stock sells with inventory turnover and days on hand.
Frequently asked questions
What is the difference between markup and margin?
Both compare profit to a price, but markup divides the profit by your cost and margin divides it by the selling price. An item that costs $60 and sells for $100 makes $40 of profit: that is a 66.67% markup and a 40% margin. Mixing them up is a common way to underprice, because a 40% markup on a $60 cost gives $84, not the $100 that a 40% margin needs.
How do you calculate a break-even point?
Divide your fixed costs by the contribution margin per unit, which is the selling price minus the variable cost of each unit. With $5,000 a month in fixed costs, a $50 price and $30 of variable cost, each sale contributes $20, so you break even at 250 units, or $12,500 in sales. Add a profit target to the fixed costs to see how many units you need to earn it.
How is sales commission calculated?
On a flat plan, commission is sales times the rate: 10% of $80,000 is $8,000. A quota plan pays one rate on sales up to the quota and a higher accelerator rate only on the sales above it, and a tiered plan pays each band of sales at its own rate. Total pay for the period is base salary plus commission.
