Page scope
A product sells for $80 with $50 in direct costs.
Shows a 37.5% gross margin and 60% markup.
Revenue $200K, COGS $120K, operating costs $40K.
Shows both gross margin (40%) and net margin (20%).
Use this page to calculate both markup percentage and gross profit margin from cost and selling price, and to understand when each number is the right one to use.
Use the landed cost — the amount you pay including any shipping, import duties, or production costs, before any selling expense.
Use the price the customer pays before any discounts. Add operating expenses if you want to see net margin alongside gross margin.
This is profit divided by cost. Use it when you are building prices from a cost-plus model or quoting jobs with a standard uplift.
This is profit divided by revenue. Use it when comparing to industry benchmarks or reporting profitability to stakeholders who reason in margin terms.

Margin and markup are the two most common ways to express profitability, but they measure different things. Margin expresses profit as a share of revenue; markup expresses it as a share of cost. Confusing the two leads to pricing errors, so having both side by side prevents mistakes.
Many FIRE plans fail before they start because the number is chosen for emotional comfort rather than built from expenses, time horizon, return assumptions, and the drag of real-world costs. A credible FIRE target should be a planning model, not a slogan.
Rent-versus-buy decisions go wrong when buyers anchor on a single metric such as monthly payment or future home appreciation. A better comparison treats housing as a bundle of tradeoffs: time horizon, flexibility, cash commitment, maintenance risk, and what the down payment could do elsewhere.
Investors often use a growth calculator and then feel surprised when the real account value lands lower than the projection. That gap usually comes from mixing two separate questions: how money compounds when assumptions go well, and how ongoing fees quietly reduce the outcome year after year.
These tools look similar because both deal with housing costs, but they answer different decisions. Mortgage Affordability Planner asks how much home payment you can realistically carry. Rent vs Buy Calculator asks whether buying beats renting under your time horizon, cash position, and cost assumptions.
Retirement planning users often assume paid software must be more serious than free calculators. That can be true, but not always. The right choice depends on how complex the planning situation is and whether the paid layer removes a real problem or just adds a shinier interface to questions a focused calculator already answers well.
