Calculation tables

A calculation table is a structured way of organizing and presenting data to perform calculations. It typically consists of rows and columns, where each row represents a set of input values or variables, and each column represents a calculation or result based on those input values.

Calculation tables can be used to calculate and compare values, perform what-if analysis, and visualize relationships between variables.

For example, a mortgage calculator might use a calculation table to show the monthly mortgage payments for different loan amounts, interest rates, and loan terms. The table would list different combinations of these variables in rows and calculate the corresponding monthly payments in columns.

Calculation tables can be created manually using spreadsheet software like Microsoft Excel or Google Sheets, or they can be generated automatically by software or programming languages to perform complex calculations.
