The Differences between Murabahah and Musharakah Muatanaqisah Contract Payments Using the Time Value of Money Method (Study Case: PT Sarana Perumahan Mandiri)
Indonesia’s population is expected to grow by 68% by 2050, with the government aiming to improve living conditions and promote economic expansion. The Million Homes Program will determine the nation’s future. Islamic banks offer mortgage financing options, including Musharakah, Murabahah, and Ijarah contracts. These contracts require a thorough risk assessment and understanding of each party’s responsibilities. The study aims to determine the ideal contract for Islamic bank mortgages, allowing developers to advise clients on their use before purchasing subsidized homes. The authors used contracts called Murabahah and Musharakah to calculate financing, but found that the equivalent rates on each contract varied, raising concerns about the amount of finance developers and buyers need to provide. The Time Value of Money technique was employed to calculate the cost difference between the Murabaha and Musharakah contracts. The results suggest that customers may choose Bank Syariah B or Bank Syariah A based on lower equivalent rates and stability. With a margin of 67.79% in the Musharakah contract, Bank Syariah B can be chosen with an equivalent rate of 7.5% for the first 13 years, 10.1% on the 14th year, and then falling back to 10.1% on the 15th year.
