Honest note on the math: These totals sum each item's quantity × cost-per-unit. For items you keep stocked, this is current stocked value (replacement cost). For maintenance parts you buy and use up, update the quantity to reflect total purchased that year. The Pro version keeps this synced to your account so it's there every time you log in — this free tool saves only to this device.
