Frequently asked questions

How is the monthly Loan EMI calculated?

Loan EMI is computed using the standard reducing-balance amortisation formula: EMI = [P × r × (1 + r)^n] / [(1 + r)^n - 1], where P is loan principal, r is the monthly interest rate (annual rate / 12 / 100), and n is the total number of monthly payments. The calculator also produces a full annual amortization schedule.

What is the difference between Profit Margin and Markup?

Profit Margin is the percentage of the selling price that is profit: Margin % = (Profit / Revenue) × 100. Markup is the percentage added to the original cost to establish the selling price: Markup % = (Profit / Cost) × 100. A 50% markup corresponds to a 33.33% profit margin.

Can I enter custom GST or VAT rates?

Yes. Our tax calculators provide quick presets for common global tax brackets (such as 5%, 12%, 18%, 20%, 28%) and allow you to enter any custom percentage rate to match your specific country, province, or product tax jurisdiction.

Does the Break-Even Calculator support target profit goals?

Yes. In addition to calculating the zero-loss break-even volume (Fixed Costs / Unit Contribution Margin), you can enter a desired target profit amount to discover the exact sales units and turnover needed to reach that profit goal.

Are financial calculations private and secure?

Yes. All financial formulas execute 100% locally in your browser memory. No loan amounts, income figures, tax numbers, or corporate revenue data are ever transmitted to any remote server.
