Daily estimateEnter an amount
Scheduled payments are deducted from your remaining budget, then the result is divided by the days left.
This result is an estimate to help you plan your household budget. Do not use it to make tax, investment, or borrowing decisions. Consult a qualified professional when needed.
Formula and example
Subtract scheduled payments from your remaining budget first
Daily estimate = (Remaining budget − Scheduled payments) ÷ Days left, including today
For example, with $500.00 remaining, $80.00 in upcoming payments and 15 days until month-end, $420.00 ÷ 15 gives $28.00 per day. Fractions of a yen or cent are rounded down. If upcoming payments use up the remaining budget, the result is zero.
Monthly budget in Kurashi OS is your total spending budget for the month. In this calculator's Amount left to spend this month field, enter that total minus recorded expenses. With matching scheduled payments and days left, the result matches the new board's daily average when the amount remaining after scheduled payments is JPY 0 or more. The board may show a negative estimate to make overspending visible.
