假设月利率为R,则:
100000/(P/A,R,36)=3000
(P/A,R,36)=100000/3000=33.33333333
当R=0.4%时,(P/A,0.4%,36)=33.46587589
当R=0.5%时,(P/A,0.5%,36)=32.87101624
使用插值法计算月利率R=(0.4%-0.5%)/((33.46587589-32.87101624)/(33.33333333-32.87101624))+0.5%=0.42228132%
实际贷款利率=0.42228132%*12=5.0674%
100000/(P/A,R,36)=3000
(P/A,R,36)=100000/3000=33.33333333
当R=0.4%时,(P/A,0.4%,36)=33.46587589
当R=0.5%时,(P/A,0.5%,36)=32.87101624
使用插值法计算月利率R=(0.4%-0.5%)/((33.46587589-32.87101624)/(33.33333333-32.87101624))+0.5%=0.42228132%
实际贷款利率=0.42228132%*12=5.0674%
