Gain insight rather than just do computations
An online calculator is just a tool to solve a numerical problem. Most people want an answer to a question in real life. To get this answer they may need to translate that question to a numerical problem. The better you can formulate your question, the easier it is to translate it to a numerical problem. So what matters is formulating your question. This website tries to help you formulating your question by providing examples of real life questions and giving instructions on how to answer these questions with one of the calculators.
Many calculators on this website are designed to improve your insight into your question further. They often output diagrams and provide ways to solve for more than one parameter. An example is the loan calculator. With this calculator you can either compute the interest rate, or the loan amount, or the monthly amount, or the number of terms or the remaining debt. By doing computations with different input and output parameters, e.g. first with the interest rate as output and than with the remaining debt, your insight into your question will often improve.
If your browser does not have print facilities you can capture the browser window and print that as a screenshot. On Windows select the browser window active and then press the key combination ALT-PrtSc, without pressing the Shift key. Then paste to a Word- or OpenOffice document and print the document.
Computations within the fields
You can do small computations in the fields that expect numeric values. For example in the savings calculator you can enter "0.98*100" for the monthly saved amount if you save $100 per month and the transaction costs are $ 2.
