Income vs costs

Cost breakdown this month

Log a PHV shift

Log a fuel top-up

Each entry calculates actual L/100km from consecutive odometer readings, feeding into the Calculator tab.

Fuel history & consumption

Log a variable expense

Log actual out-of-pocket variable expenses here. Note: routine maintenance ($50/mo) and repair reserve ($100/mo) are already baked into the Calculator as fixed accruals — only log actual spend above those accruals here.

Month-by-month P&L

Cumulative P&L

Actual fuel economy over time

Each bar = L/100km between consecutive fill-ups. Target: ≤6.5 L/100km. Lower is better.

Fixed costs — locked in at purchase

Car ownership (economic basis, not cashflow)
Purchase price$16,300
Interest (car portion of $22k loan, 2.99% eff., 36mo)+$763

Net car cost over 16 months$14,788 · $924/mo · $30.39/day
Recurring fixed monthly accruals — unavoidable holding costs
Road tax ($506/yr)$42.17/mo · $1.39/day
Z10 PHV insurance ($2,600/yr)$216.67/mo · $7.12/day
Routine maintenance accrual$50.00/mo · $1.64/day
Repair sinking fund$100.00/mo · $3.29/day
Total fixed daily cost$43.83/day

Maintenance and repair are fixed economic accruals — they represent the true cost of running the car regardless of whether a specific repair occurs this month. A month without a repair bill is not a free month; the sinking fund builds toward the next inevitable cost.
