NPV and depreciation method method

ruchita

Is it true that: NPV under straight line depreciation method is lower than MACR depreciation method?

My approach: depreciation under straight line is even through years. Though, depreciation under MACR is higher beginning years, lower later years, which implies lower NI beginning years and higher later years. These NIs got discounted at lower rates begin years and higher rates later years, which might results in lower NPV relatively to NPV under straight line.
