Present Value of Annuity Formula

The present value of an annuity formula is used to calculate the present value of a series of periodic payments. The payments are for the same amount, made at the end of each period, and a discount rate i% is applied.

Loan Constant Tables

The loan constant tables can be used to carry out annuity calculations without the use of a financial calculator. In particular, the tables can be used to calculate the repayments and the outstanding balance on a fixed interest loan.

How to Calculate a Debt Constant

The debt constant sometimes referred to as the loan constant or mortgage loan constant is the ratio of the constant periodic payment on a loan to the original loan.

The debt service constant is only relevant to loans that have a fixed interest rate over the term of the loan, and is used to make quick calculations of the amount needed to repay a loan over its term, and the balance outstanding on the loan at any point in time.

The future value annuity tables can be used to carry out annuity calculations without the use of a financial calculator.

The tables give the value at the end of period n of 1 received at the end of each period for n periods, at a discount rate of i%.

Present Value Annuity Tables
