Frequently Asked Questions
Use this annuity due formula. Enter the annual lease payment as PMT, the discount rate as k, and the lease term as n. The result is the total present cost of the lease, accounting for the timing of payments at the start of each period.
Because payments arrive one period sooner, each payment is discounted one less period, making it worth more in present value terms. The PV of an annuity due equals the ordinary annuity PV multiplied by (1 + k).
Insurance companies use this formula to calculate the present value of premium streams paid at the start of each period. It helps determine how much reserve to set aside today to cover future obligations funded by those premiums.
