With Home c8r
① Promotion of housework
② Fair sharing of household expenses
You can achieve both.

① is done by connecting housework and money. Rewarding household chores creates a good cycle of doing household chores naturally with each other.

(2) is realized by automatically calculating the share of household expenses fairly and automatically based on information such as household chores and income. The image is that the amount of household expenses shared is reduced by the amount of housework done. In addition, since it is calculated based on each other's income, for example, if you are a full-time housewife / husband, the amount of household expenses shared will be negative, and conversely, you will receive money from your household.

If you do not have a household budget, you can use only ① without using ②.

◆ Preparation for using Home c8r

1. Determination of unit price and rules for housework
Please consult and decide with two people. We have prepared some samples from the beginning, so please refer to them. It is recommended to decide the unit price from the viewpoint of the required time and physical / mental load.

2. Determination of mandatory living expenses
Please add up the expenses that are indispensable for each other's lives, especially the expenses for cosmetics and entertainment expenses that are biased between the two. This amount will be taken into account when calculating the household expense share.


◆ Calculation method of household expenses sharing
The share of household expenses is calculated from the household chores, take-home income, and required living expenses (* 1) of the two people. The base amount is determined by the ratio of income. The amount to be shared is determined by adding / subtracting half (* 2) of the difference between the required living expenses and the housework conversion amount.

* 1 This is a necessary expense that is absolutely necessary for an individual to live. Discuss with your partner to decide. For example, lunch, beauty salons, mobile phones, cosmetics, work suits, etc.

* 2 The reason for halving is that the converted amount is the difference between the two people's share. For example, if you do household chores worth 1000 yen, your household expenses will decrease by 500 yen and your partner will increase by 500 yen.


◆ Calculation formula for sharing household expenses
Total: Total amount of household expenses to be included
In1, In2: Income
Pay1, Pay2: Mandatory living expenses
Hw1, Hw2: Housework actual conversion amount
Share1, Share2: Share of household expenses

Then

Share1 = (Total * In1 / (In1 + In2)) + (-Pay1 + Pay2) / 2 + (-Hw1 + Hw2) / 2
Share2 = (Total * In2 / (In1 + In2)) + (Pay1 --Pay2) / 2 + (Hw1 --Hw2) / 2
