Target Profit Calculator
Price, variable cost and fixed cost stay constant. The result is arithmetic, not a sales forecast or a financial recommendation. Reachability and whole-unit ceilings use exact fractions of your decimal inputs. Monetary values have no safe-integer cap; whole units are limited to 9,007,199,254,740,991. Displayed decimal numbers are approximate; the report preserves exact fractions and unrounded approximations. Your currency/unit is used without conversion. Rounded-volume outcomes are separate from theoretical thresholds. Tax is modeled only in the after-tax mode, using your flat factor on positive profit; losses receive no modeled tax credit. Other modes do not assume a zero tax rate.

Arithmetic illustration only: F=12, P=7, V=3, before-tax target=5 gives threshold 17/4, minimum 5 units, revenue 35 and actual profit 8. A separate user comparison target of 0 needs 3 units and produces profit 0. These numbers are not recommended prices, costs or targets.
A QUICK WALKTHROUGH
How to use this tool
- Choose one of the three modes and enter costs, price and currency/unit.
- Enter your primary target, and tax only for the after-tax mode. Add or remove your own comparison targets.
- Calculate and compare exact thresholds with whole-volume revenue, contribution and actual profit. Read each unreachable or unsupported row.
Profit amount before tax
c = P − V; gross target = T; threshold = (F + T) / c. Round the exact fraction upward for the minimum nonnegative whole units. If F + T = 0, zero units qualify even when c ≤ 0; at c = 0 the theoretical fraction is 0/0 and undefined. Positive required profit with c ≤ 0 is unreachable.
Profit amount after tax
gross target = T / (1 − t/100), with exact 0 ≤ t < 100. Then threshold = (F + gross target) / c, with the same zero-volume boundary as before-tax amounts. Actual after-tax profit comes from the chosen whole volume, not the theoretical target.
Profit margin on revenue
d = c − (m/100)P. If d > 0, choose max(1, ceil(F/d)). Margin needs positive revenue, so zero units never qualify. If d = 0 and F = 0, every positive volume has the target margin: the smallest is 1 and the theoretical 0/0 is undefined. All other d ≤ 0 cases are unreachable. Margin targets above the contribution ratio remain in the comparison as unreachable.
Theoretical pretax profit at the fractional threshold
Theoretical pretax profit at the fractional threshold = c × q* − F; q* = Theoretical unit threshold. Whole units round the theoretical threshold upward. Actual profit is recomputed as q(P − V) − F; the theoretical target and the outcome at q units are different quantities.

Your target comparisons
Enter finite nonnegative fixed/variable costs and targets, finite positive price, and exact tax 0–<100%. Margin targets are nonnegative and have no preset upper cap. Enter 1–20 complete comparison targets matching the selected mode. All fields start blank. Exact inputs support up to 256 characters and decimal scaling up to 1,000 places; other precision is unsupported.
GOOD TO KNOW
Common questions
Why can the actual profit exceed the target?
Whole units round the theoretical threshold upward. Actual profit is recomputed as q(P − V) − F; the theoretical target and the outcome at q units are different quantities.
Profit margin on revenue
d = c − (m/100)P. If d > 0, choose max(1, ceil(F/d)). Margin needs positive revenue, so zero units never qualify. If d = 0 and F = 0, every positive volume has the target margin: the smallest is 1 and the theoretical 0/0 is undefined. All other d ≤ 0 cases are unreachable. Margin targets above the contribution ratio remain in the comparison as unreachable.
Profit amount after tax
gross target = T / (1 − t/100), with exact 0 ≤ t < 100. Then threshold = (F + gross target) / c, with the same zero-volume boundary as before-tax amounts. Actual after-tax profit comes from the chosen whole volume, not the theoretical target.
