Compare a Merchant Conversion Quote with a Supplied Issuer-Rate Scenario

A terminal's home-currency quote is not comparable with a local amount until the conversion rate and any separate issuer markup are on the same receipt. Compare the stated scenarios without assuming a future posting rate.

FIRST-LOAD

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The currency-choice receipt processes Purchase code | local-currency amount | home currency per local unit | merchant home-currency quote locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: two differently denominated prices were compared by intuition. After: one oriented benchmark and a separate markup make the signed quote difference inspectable.

Conversion-scenario arithmetic only, not financial or legal advice or a guaranteed statement amount. Confirm the benchmark orientation, additional fees and transaction terms with the card issuer before authorizing a consequential purchase.

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the currency-choice receipt, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Filing prototype — checkout unavailable

Checkout is unavailable. Browser-local, profile-scoped convenience gating is best-effort, not server-verified access. A URL or browser flag is not proof of payment. Clearing browser data removes local state; no account or cross-device recovery is provided.

Optional filing controls are a local prototype.

Checkout is unavailable. The reading above is complete; print, CSV and five local summaries are optional enhancements, not hidden answers.

Before using the currency-choice receipt

Use one local currency and one home currency throughout the run. The rate field is home-currency units per one local unit, not its reciprocal. Obtain the benchmark and a contemporaneous merchant quote from suitable sources; neither is verified by the app. The markup setting is additional to the entered benchmark. If the supplied issuer rate already includes the fee, set the additional markup accordingly rather than charging it twice. The model uses percentage markup only, excluding fixed fees, minimum fees, cash-advance rules and posting-date movement. Rows are separate purchases whose home-currency differences can be added; they are not several quotes for one purchase to be counted as several charges.

Boundary and sources

Method: Multiply local amount by home units per local unit, then multiply by one plus markup/100 for the issuer scenario. Subtract that modeled amount from the merchant home-currency quote. Positive means the quote is higher under these inputs; negative means lower. The receipt retains each rate and both totals, not merely a suggested button to press.
All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
Google’s official pricing documentation, fetched 2026-10-01, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation

Manual entry completes this currency-choice receipt for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a currency-choice receipt. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are Purchase code | local-currency amount | home currency per local unit | merchant home-currency quote; the setting is Additional issuer markup on the supplied benchmark (%). Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
