Calculating percentages, tips and loan overpayments happens in shops, restaurants and when applying for a mortgage — and a rough estimate can be costly, especially when it comes to loan obligations that last for years.
Percentages and discounts
Percentage Calculator handles three basic tasks: a percentage of a number (how much a 20% discount is on an item worth 2500), the change between two values (how much a price grew), and markup — for example, what price to set for a desired margin. Just pick the mode and enter the values — the result appears instantly, no mental math required.
Tips and splitting the bill
Tip Calculator is handy after dinner at a restaurant: enter the bill amount, choose a tip percentage and the number of people — the service shows the tip for everyone and what each person pays. No more arguments about who owes what or rounding up in the waiter's favor.
Loans and mortgages
Loan Calculator turns the loan amount, term and interest rate into a monthly payment and the total overpayment for the whole period. This lets you compare banks before visiting a branch: the same payment at different rates often means tens of thousands in overpayment difference.
Tip
Before signing an agreement, always cross-check your calculated payment against the bank's schedule — a difference of hundreds in the payment signals hidden fees or insurance included in the amount.
