You use your household account book to set a monthly budget, but you're having trouble deciding where to put the big-ticket items (TV, refrigerator, air conditioner, etc.) that suddenly become necessary.
If you use this app, it will calculate the monthly payment amount assuming you pay in installments over the purchase cycle (for example, 10 years for a refrigerator).
【example】
・TV 100,000 yen, replaced every 5 years → Monthly fee 1,666 yen
・Air conditioner 150,000 yen, replaced every 10 years → 1,250 yen per month
→Total monthly payment for high-priced items: 2,916 yen
If you budget the sum of the monthly costs of various products in your household account book as ``expenses for expensive items,'' you can also use it to determine how many more expensive items you can afford to buy.
