Target Buy Price Calculator

Work backwards from your target sell price to estimate the highest supplier price you can accept while protecting profitability

Planning model: duty and FX buffer are estimated on supplier price by default. Recoverable VAT is usually a cashflow item, not a true margin cost. Include tax only when it is non-recoverable for your entity and transaction.

Results and negotiation guidance

Use ceiling outputs to decide if quotes are commercially viable.

Ceiling ready

Negotiation anchor/unit

Max buy total

Non-product cost/unit

Recommendation

Use this ceiling when asking suppliers for quotes. Aim below the negotiation target to protect margin.

Suggested supplier message

“To hit our target margin we need to be around €3.29/unit for 1,000 units. Can you support this price?”

Next in the deal

You have your ceiling price. Now pressure-test it.

Your target buy price is the most you can pay and still hit margin. Confirm what it really lands at once freight, duty and FX are in — then check the margin it leaves before you take the number to suppliers.

Calculate true landed costCheck the margin it leaves

Understand target buy price

Work backwards from your selling price to the maximum supplier cost that still protects margin.

When to use this

  • Before RFQs, to set a negotiation ceiling.
  • When validating that landed-cost assumptions still support channel pricing.
  • When FX or duty changes force a new buy-price guardrail.

Inputs explained

What each field expects

  • Selling price
    The customer-facing price you must hit in the target channel.
  • Target margin
    The gross margin you need to leave intact after all costs.
  • Freight & handling
    Fixed per-unit add-ons between supplier and your warehouse.
  • Duty / VAT / FX buffer
    Variable add-ons estimated on supplier price unless noted.

What the output tells you

How to read each number

  • Max supplier buy price
    What the supplier can charge before landed-cost add-ons.
  • Negotiation target
    An internal opening price (~95% of the max), leaving room to move.
  • Quote verdict
    Whether a supplier quote passes, is tight, or sits above your ceiling.

Formulas

Target cost ceiling
Ceiling = Selling price × (1 − target margin%)
Max supplier price
Max supplier = Ceiling − freight − duty − VAT − FX buffer

Solved per unit using your add-on assumptions.

Worked example

  • Selling price: €40
  • Target margin: 35% → Ceiling = €26.00
  • Freight + handling: €1.50, duty 6%, FX buffer 2%
  • Max supplier price ≈ €22.69 / unit

If the supplier quote is above €22.69, the deal needs renegotiation or a price change.

Common mistakes

  • Using supplier invoice cost as if it were landed cost.
  • Treating recoverable VAT as a permanent margin cost.
  • Ignoring FX buffer and destination charges during negotiation.
  • Anchoring on supplier list price instead of your own ceiling.
Decision rule

If the supplier price is above your target buy price, the deal needs renegotiation — not a margin haircut.

About Target Buy Price Calculator

Work backward from selling price and target margin to calculate a maximum supplier buy-price ceiling per unit.

When to use it

  • Supplier negotiation guardrails.
  • Backward costing before RFQs.
  • Stress testing margin under freight, duty, and FX movement.

Calculation logic

The calculator uses these practical rules:

  • Target cost ceiling per unit = sell price × (1 − target margin%).
  • Max supplier buy price = target cost ceiling − non-product cost per unit.

Worked examples

Example
Example

Sell price $20 and target margin 35% gives cost ceiling $13.

If non-product cost is $3.10/unit, max supplier buy is $9.90/unit.

How to use

Set selling price, margin, and quantity.

Add freight, duty, VAT treatment, FX buffer, and other non-product costs.

Use the resulting max buy-price ceiling as your supplier negotiation cap.

Frequently asked questions

Should I include VAT/GST in margin cost?

Usually no when VAT/GST is fully recoverable; treat it as cashflow timing. Include it only when tax is non-recoverable or partially recoverable for your setup.

What if max buy price is negative?

Your current selling price, target margin, and non-product cost assumptions are incompatible. Revisit channel price, margin target, or landed-cost assumptions.

How should I use the negotiation target?

Use it as an internal opening anchor (for example ~95% of max ceiling) so you preserve room for supplier movement without crossing your cost limit.
