Amazon P&L Calculator: The Complete Step-by-Step Guide

If you sell on Amazon (Seller Central or FBA), you already know the pain: your Order Report shows what customers paid, your Payment/Transaction Report shows what Amazon actually settled to you after fees, and your Return Report shows what came back — and none of these three files talk to each other.

That’s exactly why we built the Amazon P&L Calculator, a free tool on EcompnlTool that automatically reconciles all three reports and shows your real profit — order by order and SKU by SKU, after Amazon’s Selling Fees, FBA Fees, Shipping, and TDS/TCS deductions.

In this guide, we’ll walk you through exactly how to use the tool, from downloading your reports on Seller Central to exporting your final profit report.

Why Amazon Sellers Need a P&L Calculator

Seller Central gives you plenty of raw reports, but no single view that combines:

Order-level sale price, quantity, and SKU from the Order Report
The actual amount Amazon settled per order, after Selling Fees, FBA Fees, shipping deductions, and TDS/TCS, from the Payment/Transaction Report
Which units came back as returns, from the Return Report
Your own product cost per SKU

Without merging all of this, sellers usually estimate profit using the order value alone — which massively overstates real margin once Amazon’s fees and returns are factored in. The Amazon P&L Calculator on EcompnlTool solves this by matching your Order, Payment, and Return reports together and calculating true profit per order and per SKU, instantly, in your browser.

What You’ll Need Before You Start

Order Report (TXT/TSV/XLSX) — Seller Central → Orders → Order Reports → All Orders → Exact Dates → Flat File
Payment/Transaction Report (CSV) — Seller Central → Reports → Finance Reports → Reports Repository → Custom Date Range (order month and next month) → Request Report
Return Report (TSV/CSV/XLSX) (optional but recommended) — Seller Central → Manage Returns → View Reports → All Returns → Exact Dates (order month and next month) → Download TSV
(Optional) A SKU cost sheet — an Excel/CSV file listing your SKU and your purchase/manufacturing cost for each one.

Note: Amazon’s Payment report often has a varying number of explanation rows at the top before the real data starts. You don’t need to clean this up manually — the calculator automatically detects where the actual header row begins.

Step-by-Step: How to Use the Amazon P&L Calculator

Step 1: Upload Your Order, Payment, and Return Reports

Open the calculator and go to the Upload step. There are three upload zones:

Order Report — drag and drop (or click to browse) your Order Report files here. You can select multiple files at once — for example, if you’re analyzing 3 months, upload all 3 monthly exports together and they’ll be merged automatically.
Payment/Transaction Report — upload your Finance report(s) here. As with orders, it’s best to select the current month and the following month together, since Amazon often settles payments a few weeks after an order is placed.
Return Report (optional) — upload your returns export here to get accurate return-related cost adjustments in your P&L.

Once your Order and Payment files are recognized, the “Set SKU Costs →” button becomes active. (The Return Report is optional, so it isn’t required to proceed.)

Step 2: Set Your Product Cost per SKU

This is the step that makes your profit numbers accurate.

You have two options:

Option A — Import costs automatically: Upload an Excel/CSV file with a column containing “SKU” and a column containing “Cost” (column names are auto-detected). You can download a ready-made template from the tool if you don’t have one yet. Every SKU that gets a cost from this file will be highlighted green in the table below.

Option B — Enter costs manually: Scroll through the SKU table (searchable by SKU or product name) and type your cost directly into the “Your Cost” field for each product.

Tip: If many of your products cost roughly the same to make or source, use the “Set all to ₹” bulk-cost box to apply one cost to every SKU in one click, then manually adjust the few that differ.

Any SKU left blank will fall back to the default cost you set in the next step — so this step is optional for a quick estimate, but strongly recommended for accurate SKU-level analysis.

Step 3: Configure Your Cost Parameters

Head to the Configure step. Here, the tool reminds you exactly how it calculates your profit:

Amazon already deducts Selling Fees, FBA Fees, Shipping, and TDS/TCS from your settlement — these are reflected in the Payment Total matched per order item. Your P&L = Payment Total − Product Cost − Packaging Cost − Misc Costs.

Set your three inputs:

Default Product Cost (₹) — used as a fallback for any SKU you didn’t price in Step 2
Packaging Cost (₹) per item — applied to Delivered, Returned, and RTO orders, multiplied by quantity
Misc Fixed Costs (₹/month) — labour, rent, electricity, or any other overhead you want reflected in your monthly profit

Because Amazon’s fees are already netted out in your Payment report, you don’t need to enter commission or shipping fees separately — the tool pulls that directly from your actual settlement data.

Step 4: Calculate and Review Your P&L

Click “Calculate P&L →” and the tool instantly processes every order — matching it against your payment settlement and return data, then applying your cost inputs. On the Results screen, you’ll see:

KPI cards for total revenue, total profit, and order counts by status
Charts breaking down profit and order outcomes visually
A detailed, filterable order table so you can drill into exactly which orders and SKUs are truly profitable — and which ones are being eroded by fees or returns
A pending orders view for orders that haven’t been fully settled yet

Step 5: Export Your Report

Once you’ve reviewed your numbers, use the action buttons to:

Download Excel Report — a full formatted workbook you can save, share, or archive
Download CSV — a raw data export for your own spreadsheet or accounting workflow
Upload New Files — start a fresh calculation for a different date range

Frequently Asked Questions

Is my data uploaded to a server? The calculator processes your Order, Payment, and Return files directly in your browser, so you stay in control of your data at every step.

Do I need to enter Amazon’s commission or FBA fees manually? No. Amazon’s Selling Fees, FBA Fees, shipping, and TDS/TCS are already deducted in your Payment/Transaction report, and the tool uses that settled amount directly — you only need to add your own product and packaging costs.

Is the Return Report mandatory? No, it’s optional. You can calculate your P&L with just the Order and Payment reports, but uploading returns gives a more accurate picture of the true cost of returned units.

Why should I upload two months of Payment reports together? Amazon typically settles payment for an order a few weeks after it’s placed, sometimes into the following month. Uploading the current and previous month’s reports together ensures more orders get matched to their actual settlement.

Can I use this for multiple months of data at once? Yes — select and upload multiple Order, Payment, and Return files in one go, and the tool merges them automatically before calculating your P&L.
