Cost comparison of retiring at 60 with selling house and buying motorhome

A simulation for a couple in their mid-50s found that retiring at 60, selling their house for 13 million yen and buying a motorhome for 7 million yen would create an annual deficit of about 4–5 million yen from ages 61 to 64. By age 65, financial assets would total about 24.1 million yen versus 43.5 million yen if working until 65; under the motorhome plan, assets would be nearly depleted by age 99 but last until 100. The difference is mainly due to forgone income from retiring five years early (about 20.9 million yen), while motorhome costs are largely offset by downsizing the house (about 5 million yen).
