Ella's Bakery plans to purchase a new oven for its store. The oven has an estimated useful life of 4 years. The estimated pretax cash flows for the oven are as shown in the table that follows, with no anticipated change in working capital. Ella's Bakery has a 10% after-tax required rate of return and a 36% income tax rate. Assume depreciation is calculated on a straight-line basis for tax purposes using the initial investment in the oven and its estimated terminal disposal value. Assume all cash flows occur at year-end except for initial investment amounts.

Requirement 1. Calculate (a) net present value, (b) payback period, and (c) internal rate of return.

a. Net present value. (Use factors to three decimal places, X.XXX. Round intermediary calculations and your final answer to the nearest whole dollar.)

The net present value is

$24,050

.

Part 2

b. Payback period. (Round your answer to two decimal places.)

The payback period in years is

3.04

.

Part 3

c. Internal rate of return. (Round intermediary calculations to the nearest whole dollar and round the IRR to two decimal places, X.XX%.)

The internal rate of return (IRR) is
