How do you calculate the break-even point?

Break-even units = fixed costs ÷ (price per unit − variable cost per unit). Break-even revenue = break-even units × price.

What is contribution margin?

The amount each sale contributes towards fixed costs and profit: price minus variable cost. As a percentage, it's that amount divided by price.

How is ROI calculated?

ROI = (amount returned − amount invested) ÷ amount invested × 100. Investing ₹2,00,000 and getting back ₹2,60,000 is a 30% ROI.

What is annualised ROI?

The yearly compound rate that would produce the same result. A 30% return over 8 months is roughly 48% a year when annualised.

You made $60,000 on $200,000, a 30% return (about 48.2% a year).

ROI = (returned − invested) ÷ invested × 100. Annualised ROI = (returned ÷ invested)^(12 ÷ months) − 1, so short periods can look dramatic. Calculated in your browser; nothing is stored.

In the ROI section, enter the amount invested, the amount returned and, optionally, the months.

About

About this tool

Your break-even point is the number of sales at which revenue exactly covers costs. Divide fixed costs by the contribution each unit makes (price minus variable cost). With ₹1,50,000 of fixed costs, a ₹1,200 price and ₹450 of variable cost per unit, you break even at 200 units, or ₹2,40,000 in revenue.

The chart shows profit at every volume, crossing zero at break-even, so you can see how quickly profit builds after that point. Add a target profit to find the sales volume you need to hit it. It's a quick way to test pricing, a launch plan or a new ad campaign.

The ROI section works for any investment: enter what you put in and what you got back to see the percentage return and net gain. Add the period in months to get an annualised (compound) figure, which makes projects of different lengths comparable.
