Financial calculations often depend on several variables. A small change in the amount, interest rate, term or tax rate can change the final result. A calculator can make the arithmetic easier, but the result is only as useful as the information entered into it.
Mortgage and Loan Calculations
Mortgage and loan calculators can help illustrate repayment amounts and the effect of different inputs. Actual borrowing costs may also depend on fees, taxes, insurance, lender conditions and other terms that are not represented by a basic calculator.
Understanding Interest
Interest calculations show how an amount can change over time depending on the principal, rate, time period and calculation method. Simple and compound interest use different formulas, so it is important to use the method that matches the situation being considered.
Calculating VAT
VAT calculations can be used to determine a price before or after tax. The applicable VAT rate depends on the country, product or service and sometimes the circumstances of the transaction. Always use the appropriate rate for the situation you are calculating.
Currency Conversion
Currency conversion involves applying an exchange rate to an amount. Exchange rates can change over time, and the rate used by a calculator may differ from the rate offered by a bank, card provider or exchange service because of fees, spreads or timing.
Getting More Useful Results
A few simple checks can make a financial calculation easier to understand.
