About business calculators on VyaparKit

Pricing a product, taking a loan for a machine, or deciding whether a 10% plus 5% discount is worth it all come down to a formula that is easy to get wrong on a phone calculator. Each tool here shows the formula, the result and a breakdown, in rupees with Indian comma grouping.

Results can be copied or shared, and the numbers flow naturally into VyaparKit documents: a markup calculation becomes the rate on a quotation, an EMI schedule becomes a line in your monthly expenses.

Business Calculators: common questions

What is the difference between margin and markup?
Margin is profit divided by selling price; markup is profit divided by cost. A product bought at ₹100 and sold at ₹125 has a 25% markup but a 20% margin. Retailers usually talk margin, wholesalers markup.
How is the EMI formula calculated?
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the principal, r the monthly rate (annual ÷ 12 ÷ 100) and n the number of months. The calculator also shows how much of each instalment is interest.
Are these calculators free to use?
Yes, all calculators, lookups and QR generators on VyaparKit are free and do not need an account. Only document generators and PDF tools need a free login.
