Find the sale price after a discount, or work backward from a sale price to find the original.
Margin and markup are easy to mix up — margin is profit as a % of price, markup is profit as a % of cost. They're always different numbers for the same sale (except at 0%).
Build a year-by-year depreciation schedule using the straight-line or declining balance method.
| Year | Depreciation Expense | Accumulated Depreciation | Book Value |

original × (1 − discount%/100); reverse mode solves original = sale ÷ (1 − discount%/100). Margin is profit ÷ selling price; markup is profit ÷ cost — they are not the same percent. Depreciation uses the method on that tab (straight-line or reducing balance) with the rate and life you type, not a tax schedule.
Margin is profit divided by selling price; markup is profit divided by cost. The same dollar profit produces two different percentages depending which figure you divide by, which is why they're kept as separate tabs here.
Use the reverse discount mode: enter the sale price and the discount percentage, and the calculator solves original price = sale price ÷ (1 − discount% ÷ 100).
Straight-line spreads the same dollar amount of depreciation evenly across every year of the asset's life. Reducing balance applies the same percentage to a shrinking balance each year, so the dollar amount is larger early on and smaller in later years.
No — it's a generic accounting calculation using whichever method, rate and life you enter, not a specific jurisdiction's tax depreciation schedule. Check your local tax rules for what's actually deductible.
