Use this calculator to understand how the “CA” function works on a scientific calculator, allowing you to calculate missing variables in equations.
What is CA on a Calculator?
CA Formula
The CA function on a calculator helps solve for the missing value in an equation involving time value of money. The formulas are:
- Future Value (F) = Present Value (P) × (1 + Interest Rate) ^ Number of Periods
- Present Value (P) = Future Value (F) / (1 + Interest Rate) ^ Number of Periods
- Interest Rate (V) = (Future Value (F) / Present Value (P)) ^ (1 / Number of Periods) – 1
- Number of Periods (Q) = log(Future Value (F) / Present Value (P)) / log(1 + Interest Rate)
