Charm Pricing

​

What Is Charm Pricing?

Adaptive Currency converts your base price at live exchange rates. The result is an accurate number, but rarely an attractive one: a $47.00 product can show as €43.12 today and €43.47 tomorrow. Charm Pricing takes that converted amount and moves it to the nearest clean ending. The customer sees 49.99, not 43.12. The ending stays stable while exchange rates move. You do not set a price per market. You choose one rounding rule, and it applies to every currency.

​

Key Benefits

• Clean prices in every currency: One rule covers all markets. You do not maintain a price list.
• Stable endings: The ending does not change when the exchange rate moves a few percent.
• No conversion artifacts: Customers never see 43.12 or 1043.87.
• Automatic for new markets: A currency you never priced still gets a clean number.

How the Price Is Calculated

Dodo Payments charms the per-unit price, after currency conversion and after any discount, and before tax.

1. Find the step. The amount selects a step from the rounding-step table. A $47 price falls in the 10–99 range, so the step is 10.
2. Pick the target. The step gives two candidates, 40 and 50. The rounding type picks one. With Nearest, 47 is closer to 50.
3. Shave the ending. Dodo Payments subtracts one thousandth of the step, so 50 becomes 49.99. The shave is never less than one minor unit. Whole skips this step.

Rounding types

​

Rounding steps

The step depends on the size of the price, in the currency’s main unit. These are the defaults. You can change the Rounding step for any range. You cannot change the ranges themselves. The step stops growing at 10,000. This keeps the change small for large amounts, and it matters for currencies with many units per dollar, such as IDR and VND.

Worked examples

​

When charm does not apply

Dodo Payments keeps the converted price unchanged in these cases:

• The step is wider than the price. The price cannot move by less than one full step.
• The result would be zero or less.
• No step matches the amount.

​

How It Applies at Checkout

Charm Pricing is the last step in the price calculation. For a product with no localized price, the order is:

1. Base price — the price you set on the product.
2. Purchasing Power Parity — if the product opted in, the country percentage applies.
3. Discounts — any product discount and discount code apply.
4. Currency conversion — the discounted amount converts to the customer’s currency at the live rate.
5. Charm rounding — the result moves to the clean ending.
6. Tax — calculated from the charmed amount. See Tax-Inclusive Pricing.

Each cart line is calculated on its own. The strikethrough “before discount” price uses the same rounding step as the charged price, so charm never shows as a discount you did not give.

​

Subscriptions

A subscription records its rounding step and rounding type when the customer subscribes. Dodo Payments repeats that same decision at every renewal. What is frozen: the rounding step and the rounding type. If you edit a step, or change the rounding type, an existing subscription is not repriced. The customer keeps the rule they agreed to. What can move: the amount. Each renewal converts the price at the current exchange rate, then applies the frozen rule. A large rate movement can change the renewal amount, even though the rule did not change.

Important Behaviors

​

Best Practices

• Start with Nearest. It moves the price the least. Use Floor only when you accept the discount it creates.
• Check your largest and smallest products. The step changes with the price range, so a $5 product and a $1,200 product behave differently.
• Review the step for high-unit currencies. IDR, VND, and KRW prices land in the top ranges, where the step is fixed at 10,000.
• Price your subscriptions before you launch. Editing a step later does not reprice existing subscribers.
• Account for the conversion fee. A charmed line is fees-inclusive, so the fee comes out of your revenue.
