When you spend the same amount on several purchases, the number of units changes with the price. The average amount paid per unit must use the actual units acquired. Simply averaging the market prices gives a different answer.

The DCA calculator accepts a sequence you supply. It does not fetch historical prices or claim to backtest a strategy.

Follow the cash and the units

Consider two purchases with a total budget of 120 each. At a price of 60, the first buys two units. At a price of 40, the second buys three. Total spending is 240 and total holdings are five units, so the average acquisition cost is 48 per unit. The simple average of 60 and 40 is 50; it ignores how many units were acquired at each price.

Decide where fees come from

Our model deducts the percentage purchase fee from each budget. With a 1% fee, each 120 budget leaves 118.80 to buy units. The two purchases acquire 1.98 and 2.97 units, or 4.95 in total. Cash spending remains 240, and all-in average cost becomes approximately 48.4848.

If your exchange instead charges a fee on top, or takes it in another asset, translate the cash flows before using this model. A fixed minimum fee can also change a small purchase substantially; this tool currently models percentage fees only.

Valuation is a separate assumption

At a later valuation price of 50, those 4.95 units are worth 247.50 before an exit fee. With a 1% hypothetical selling fee, net proceeds would be 245.025 before rounding: approximately 5.03 above the original 240 spending. A valuation price of 40 instead produces a loss. Lower average entry does not ensure profit.

What the sequence cannot tell you

Equal-budget purchases are commonly called dollar-cost averaging when they occur at regular intervals. This calculator assumes that schedule rather than validating dates. It does not include dividends, interest on uninvested cash, tax lots or changes in exchange rates. The result is a scenario based on your inputs, not a recommendation to buy an asset or evidence of future performance.

For unequal purchase quantities, use the weighted average purchase price calculator. For a single completed spot trade, use the stock and crypto profit calculator.

A move of 50 pips is not a complete profit figure. Its cash value also depends on position size, pip size and the currency of the account. The Forex profit calculator keeps these quantities visible so that a currency conversion is not silently assumed.

Start with the actual position

Imagine a long EUR/USD position of 0.2 lots, with 100,000 EUR per lot. The position contains 20,000 EUR. If the entry fill is 1.1000 and the exit fill is 1.1030, the positive price difference is 0.0030 USD per EUR. Multiplying by 20,000 gives 60 USD gross profit.

With a pip size of 0.0001, that move is 30 pips and each pip is worth 2 USD for this position. If your instrument uses a different contract size or pip convention, enter those specifications instead of assuming this example applies.

Convert in the correct direction

Suppose the account currency is EUR and the conversion input is 0.90 EUR per USD. The 60 USD gross result becomes 54 EUR. Subtracting 4 EUR of additional costs leaves 50 EUR. Entering the reciprocal rate would produce an incorrect account result.

For a short position, a falling price creates a positive signed move; a rising price creates a negative one. The calculator handles this through its direction selector. Actual broker conversion can include a spread or use different rates for gains and losses; enter the appropriate effective rate for your scenario.

Avoid subtracting the spread twice

If you enter actual entry and exit fills, their bid/ask differences are already reflected in the prices. Additional costs should include only charges not already captured, such as a separate commission or a funding debit. Do not take a net statement result and deduct the same fees again.

Profit is not margin or risk

This model does not establish how much margin the broker requires or where liquidation would happen. Nor does a planned stop guarantee a maximum loss. Use the position size calculator for a chosen risk budget and the pip value calculator to check units separately. These are planning calculations, not trade recommendations.

The amount a customer pays and the amount remaining after processing are different numbers. When planning a payment, calculate both; a percentage alone misses the fixed charge on each transaction.

The Stripe fee calculator covers US standard online card pricing in USD. It is not a universal Stripe calculator for every country or product.

Use the right pricing scope

As checked on 14 October 2026, the linked US schedule lists 2.9% plus $0.30 for domestic online cards, with applicable additions for international cards, required currency conversion and manual entry. The tool exposes those options. Use your own contract if you have negotiated pricing.

A small payment example

Under the domestic model, a $20 payment has an estimated fee of $0.88 and leaves $19.12. Ten separate $20 payments incur ten fixed charges. A single $200 payment has the same percentage component but only one fixed charge, so the modelled total is different. This illustrates fee mechanics; it does not recommend changing how customers are billed.

Work backwards carefully

To solve for a gross amount that leaves a target net, add the fixed charge to the target and divide by one minus the percentage. For a target net of $20, the unrounded gross amount is $20.30 ÷ 0.971, or about $20.9063. Rounding upward gives $20.91.

Adding 2.9% to the target is not the same calculation, because the processing percentage applies to the final gross charge. The reverse calculation is arithmetic, not permission to surcharge a payment method. Applicable rules and your agreement remain separate questions.

Where this estimate stops

The tool does not calculate the total cost of operating a Stripe account. Other payment methods, recurring-billing products, tax services, disputes, refunds, Connect and payout choices can have separate charges. The underlying fee schedule is dated and should be rechecked before quoting a customer.

For a custom percentage and fixed charge, use the general payment fee calculator. To evaluate product profitability, combine processing costs with your other direct costs in the margin calculator.

A percentage attached to a price is incomplete until you know its denominator. A 30% markup and a 30% gross margin produce different selling prices from the same cost. This matters when a supplier, sales team and business owner use the word “margin” differently.

Open the margin and markup calculator and choose “Find price for target margin” to work backwards from your own cost.

A pricing example from both directions

Suppose a unit costs 70. Selling it at 100 leaves 30 gross profit. That profit is 30% of the selling price, but approximately 42.86% of the cost. A 30% markup on the same cost instead sets the price at 91, leaving 21 profit and approximately 23.08% gross margin.

Calculate a price for your target

For a target margin expressed as a decimal, divide cost by one minus the margin. At cost 70 and margin 0.30, the price is 70 ÷ 0.70 = 100. For target markup, multiply cost by one plus the markup. At 30% markup, the calculation is 70 × 1.30 = 91.

The calculator keeps the two modes separate and also displays a price rounded upward to cents. A 100% gross margin is not achievable with a positive cost and finite selling price; it is therefore rejected as a target.

Check your definition of cost

Use consistent amounts: one unit of product, one service package or one project. Do not compare an entire monthly expense with the price of a single item. Decide which direct costs belong to that unit and avoid mixing tax-inclusive selling prices with tax-exclusive costs.

These calculations do not automatically include rent, salaries, income taxes or finance costs. A healthy-looking gross margin can coexist with an overall loss. Use the break-even calculator to examine fixed-cost coverage separately.

Discounts change more than the price

In the first example, a 10% discount changes the price from 100 to 90 and profit from 30 to 20. Restoring the original total gross profit would require 1.5 times as many units, assuming costs do not change. That is an arithmetic requirement, not a prediction that demand will rise.

Test that situation with the discount impact calculator before accepting a percentage discount.

An Etsy order total can include money that is not seller revenue. It can also trigger several charges with different calculation bases. A useful profit estimate separates these amounts before subtracting product and fulfilment costs.

Use the US Etsy fee and profit calculator for a US shop with a US bank account, USD listings and USD settlement.

Build an order ledger

Consider an illustrative order containing a $50 item, $5 charged shipping and $4 of sales tax collected and remitted by Etsy. The customer total is $59, but seller revenue is $55. Suppose product and packaging cost $20, actual postage costs $5 and one listing charge is allocated to this order.

Under the dated US model, the transaction fee rounds to $3.58, processing is $2.02 and the listing allocation is $0.20. Estimated platform fees total $5.80, leaving $24.20 after the entered product and postage costs. Keeping remitted tax in revenue would overstate the result.

An attributed ad changes the outcome

Select an Offsite Ads rate only when the order is attributed and use the rate applicable to the shop. The official policy describes 12% and 15% rates and a $100 per-order cap. In this example, a 15% fee on the modelled base adds $8.25, leaving $15.95 after the same costs. The calculator does not determine whether Etsy attributed the order.

Allocate costs deliberately

The number of listing charges is an input rather than an assumption that every sale has exactly one charge. Allocate relevant renewals or other listing costs consistently. Add an allocation for Etsy Ads, labour or other expenses only once: do not include the same amount in both product costs and the additional-cost field.

Shipping charged to the buyer and actual postage are different inputs. Offering “free shipping” means entering zero charged shipping while still entering the fulfilment expense. It does not make shipping cost disappear.

Read the result as order contribution

The estimated profit covers the entered order costs. It is not a complete business income statement or a tax calculation. Shop setup, subscriptions, refunds, currency conversion, fee taxes and other overhead need separate treatment when applicable. Use the break-even tool to explore fixed-cost coverage and the discount tool for a simplified pricing scenario.
