How Fba Planner Yearly Actually Works for Amazon Sellers
I've been running FBA listings for about six years now, and I went through at least eight different inventory management tools before settling on Fba Planner Yearly. Most of those were garbage. A couple were functional but overpriced. This one is neither of those things, which is why it stuck around. Fba Planner Yearly is essentially a spreadsheet-based planning system built for Amazon FBA sellers who want to forecast inventory needs across a full 12-month cycle. It's not software you download and install. You get access to a Google Sheets or Excel workbook that calculates reorder points, seasonal demand curves, cash flow projections, and storage fee estimates. The template does the heavy lifting if you feed it accurate data. It won't do it for you.
Getting Started With Fba Planner Yearly
Download the planner from the creator's site. The current version runs as a shared Google Sheet with a locked template sheet and an input sheet where you enter your product data. I've seen people waste hours trying to edit the locked cells, so don't bother. The creators actually made the input sheet accessible for a reason. Here's the workflow. First, pull your Amazon Seller Central sales reports for the past 12 months. Get the unit session percentage, total units sold per month, and any returns data. If you're a newer seller without a full year of history, use your best estimate and flag it as such in the notes column. The planner has a sensitivity analysis tab that shows you how wrong your estimates can be before the model breaks. That tab saved me during a product launch where my actual sell-through rate was 40% below forecast. Enter your cost of goods, shipping cost per unit, Amazon referral fees, FBA fulfillment fees, and monthly storage rates. The planner pulls current FBA fee schedules automatically if you update the fee reference sheet, but honestly, the fee tables in there are usually a few months behind. I update mine quarterly. Amazon changes fees twice a year, usually in January and October.
The reorder point calculator uses a basic formula: average daily sales multiplied by lead time in days plus safety stock. Safety stock is where most beginners mess up. The default is 30 days of buffer inventory, but if your supplier is in China and shipping takes 45 days, 30 days of safety stock means you're ordering too late. I set mine to 60 days for ocean freight products and 20 days for air freight or domestic suppliers. The planner will show you a visual calendar of when to order next, which eliminates the guesswork that used to keep me awake on weeknights.

The Part Nobody Talks About
The planner assumes consistent sell-through. That's fine for established products with stable demand. It falls apart completely for anything seasonal or promotional. I ran into this last December when I had a product that sold 12 units a day from January through November, then jumped to 60 units a day in December due to holiday demand. The planner told me to order 144 units for the month. I ended up stockd out by December 8th because the model was averaging my annual run rate, not accounting for the seasonal spike. The workaround is the seasonality adjustment tab. You input expected demand multipliers for each month. For my holiday product, I set December to 5x and November to 1.5x. The planner recalculates the entire year based on those multipliers. It took me three months to figure that tab even existed because it's buried in a separate section of the workbook. The documentation is sparse. Another edge case that tripped me up: gift card or promotional credit inflates your sales numbers but not your actual cash flow. The planner shows revenue based on units sold, not cash received. If you're running heavy PPC campaigns or coupon discounts, your gross revenue looks great and your net profit tells a different story. There's a profit calculation sheet you need to manually adjust for ad spend percentages. I started tracking my ACoS separately and feeding it into the planner each month rather than assuming the default 15% ad cost the template suggests.
What It Doesn't Do
Fba Planner Yearly won't connect to your Amazon account. You have to manually export and input your data. This is either a feature or a bug depending on how much you trust automated integrations. I prefer manual entry because it forces you to actually look at your numbers instead of setting something up and forgetting about it. But if you're managing 50+ SKUs, the manual entry becomes a real time sink. I've spent whole Sundays just transferring data from Seller Central into the sheets. It also doesn't account for supply chain disruptions. When I had a supplier delay on a product in early 2024, the planner had already committed me to reorder schedules based on normal lead times. There's no real-time supply chain monitoring. You need to update the lead time input manually whenever something changes, and I won't lie, I wasn't consistent about that. I should have been. The storage fee calculator uses standard monthly rates, but if you're hitting long-term storage fee thresholds or facing peak season surcharges, those calculations get loose. Amazon changes storage fee structures periodically and the planner doesn't auto-update. I learned this the hard way when I got hit with a $2,300 long-term storage charge that the planner had predicted would never happen.
Is It Worth It
At the yearly subscription price, it's reasonable if you're serious about FBA. The spreadsheet approach means no monthly subscription creep, no platform lock-in, and you own your data. The tradeoff is that you need to know what you're doing with spreadsheets. If you're not comfortable editing formulas or understanding conditional formatting, this tool will frustrate you. There are paid alternatives that offer dashboards and automation, but those cost significantly more and tie your data to their platform. I'd recommend pairing this with a simple PPC tracking sheet and a supplier communication log. The planner handles inventory math well. It doesn't handle the business operations side. I've been using it as my central planning document for about 18 months now, and my stockout rate dropped from roughly 12% to under 4% once I figured out how to properly calibrate the safety stock and seasonality inputs. That's not a small difference when you're talking about lost ranking and wasted ad spend. One thing I wish the creators would add is a scenario comparison feature. Right now you can only run one forecast at a time. Being able to compare an optimistic, baseline, and pessimistic demand scenario side by side would make this genuinely useful for quarterly planning meetings or when deciding whether to increase inventory budgets. Until then, you just duplicate the sheet and adjust inputs manually, which works but isn't elegant.
