About Percentage & Finance Calculator

The loan figures use the standard amortising formula, where the monthly payment stays level while the split between interest and principal shifts across the term. That is why total interest, rather than the monthly number, is the figure worth comparing between two offers.

Calculate the tip, the grand total and each person's fair share from any bill amount and tip percentage — ideal for splitting a restaurant cheque. Everything is worked out in your browser.

Work out percentages and percentage change, sale discounts and final prices, tip splits per person, and monthly loan or EMI payments with total interest — all in one place. It covers the everyday money maths that comes up while shopping, dining out, budgeting and comparing loans.

Switch between modes to answer 'what is X% of Y', 'how much do I save', 'what is each person's share' or 'what will this loan cost'. Percentage change is the one to double-check: 40 rising to 50 is a 25% increase, while 50 falling back to 40 is a 20% decrease.

Frequently asked questions

How much should I tip?

It is entirely local. In the United States 15–20% is standard for table service; much of Europe rounds up or leaves 5–10%; in Japan tipping can be actively unwelcome. The calculator handles the arithmetic — the percentage is your call.

Should I tip on the pre-tax or post-tax total?

Convention in the US is to tip on the pre-tax subtotal, though many people simply use the total for convenience — on a typical bill the difference is small. Enter whichever figure you want to tip on.

How do I split a bill unevenly?

The split assumes equal shares. When one person's order was much larger, calculate the tip on the full bill, then divide it in proportion to what each person ordered rather than by headcount.

Common Use Cases

  • •Splitting a restaurant bill between friends without doing mental arithmetic
  • •Working out a fair tip percentage when travelling somewhere with different norms
  • •Checking whether a service charge has already been added before tipping again
