Interpolation is a mathematical process to estimate the value of a dependent variable based on the values of known surrounding dependent variables, where the dependent variable is a function of an independent variable. It's used to determine interest rates for periods of time that are not published or otherwise made available. In this case, the interest rate is the dependent variable, and the length of time is the independent variable. To interpolate an interest rate, you'll need the interest rate of a shorter period of time and a longer period of time. 1. Subtract the interest rate of a time period shorter than the time period of the desired interest rate from the interest rate of a time period longer than the time period of the desired interest rate. How to Interpolate Interest Rates 2. Divide the result from Step 1 by the difference between the lengths of the two time periods. 3. Multiply the result from Step 2 by the difference between the length of time for the desired interest rate and the length of time for the interest rate with shortest length of time 4. Add the result from Step 3 to the interest rate for the shortest known time period. The linear interpolation is an estimate for the interest rate of a specic time period, and it assumes that the interest rate changes on a straight line basis between each day. In reality, interest rates may follow a "yield curve" instead of a straight line. The estimate will be more accurate the shorter the period of time between the known interest rates you are interpolating from. 6.
