The four levers
Margin only moves in four ways: charge more, spend less making it, spend less running the business, or sell a better mix. Every tactic below pulls one of those levers.
Every point of margin you add flows straight to the bottom line. Here are ten practical ways to widen it — grouped by the four levers that actually move the number.
Margin only moves in four ways: charge more, spend less making it, spend less running the business, or sell a better mix. Every tactic below pulls one of those levers.
Whichever levers you pull, check the effect with the profit margin calculator before and after, and benchmark against typical margins for your industry so you know when your margin is genuinely healthy.

The four broad levers are: raise prices, lower your cost of goods, cut overheads and fees, and shift your sales mix toward higher-margin products. Small gains in several areas usually beat one big change, and raising prices is often the fastest lever because it flows straight to the bottom line.
Not always — if a price rise loses more sales than it gains in margin, total profit can fall. But because a price increase adds pure profit per unit, you can often lose some volume and still come out ahead. Test small increases and watch the effect on total profit, not just units sold.
Reviewing prices is usually fastest, because every extra dollar of price is an extra dollar of profit with no added cost. Cutting an unnecessary fee or negotiating a shipping discount is a close second, since those savings also flow straight through.
Fees on Etsy, Amazon and eBay can take 10%–30% of revenue, directly reducing your net margin. Reducing them — by opting out of optional ad programs, hitting fee tiers, or moving some sales to your own store — is one of the most effective margin improvements for online sellers.
Both, but start with margin: a healthier margin means every extra sale is worth more, so growth compounds. Once your margin is solid, pursue volume through higher average order value and more customers.
