2週間満期預金の利息を算出すると、国税のみ増加のところで同一利息（109万＝110万、他）となり、地方税
増加のところでは1円減少し、利息の逆転（104万＞105万、他）や、同一利息（103万＝105万、他）となる。
左から、元金　税引前利息　国税　地方税　税引後利息の順。

結論： 200万以上1口よりも100万以上200万未満複数口の上手な組合せの方が利息高。
例： 104万(113)+101万(109)＝103万(112)+102万(110)＞205万(221)＞105万(112)+100万(108)　※以下括弧内は税引後利息
例： 103万(112)+103万(112)＞104万(113)+102万(110)＞106万(114)+100万(108)＝206万(222)＞105万(112)+101万(109)
例： 104万(113)+104万(113)+104万(113)＞200万(215)+104万(113)＞156万(168)+156万(168)＝312万(336)
例： 104万(113)+104万(113)+104万(113)+104万(113)＞208万(225)+208万(225)＞416万(448)＞300万(322)+116万(125)
