Finance & Business Calculators

Free finance calculators for markup, debt payoff, debt snowball and dividend yield. Instant results for business owners and investors โ€” no signup needed.

Whether you're pricing a product, paying down debt, or evaluating a dividend stock, running the numbers yourself is the only way to make a confident decision. These calculators handle the arithmetic so you can focus on strategy โ€” no spreadsheet required.

What these tools cover

The markup calculator works in three modes: cost + markup %, cost + selling price, or selling price + margin % โ€” and explains the difference between markup and margin so you don't misprice. The debt snowball calculator builds a full payoff schedule, showing exactly which month each balance hits zero and how much interest you save. The debt payoff calculator handles a single debt with custom extra payments. The dividend yield calculator solves for yield, annual dividend, or share price given the other two.

A note on accuracy

Debt payoff schedules assume a fixed interest rate and consistent monthly payments. Real credit card rates vary; actual payoff dates may differ if your rate changes or you miss a payment. These tools are for planning and education โ€” consult a financial adviser for decisions that affect your long-term finances.
