1. Amazon Fee Calculator
Stop losing margin to hidden costs. This isn’t just a basic estimator. Our fee calculator breaks down your referral fees, FBA fulfillment costs, and monthly storage fees, then contrasts them against your product costs and ad spend.
Compare FBA vs. FBM in real-time to see which fulfillment model actually protects your bottom line.
- Best for: Product research, break-even analysis, and fulfillment method comparisons.
- Key Features: Automatic category-based referral fee calculation, FBA size-tier estimation, and FBM shipping toggles.
2. Amazon FBA & Revenue Calculator
Know your true take-home profit before you invest. Planning for growth? Don’t just look at revenue. Our FBA & Revenue Calculator helps you project your net profit over a 6-month window. Input your unit costs, growth rates, and return percentages to see a realistic forecast of your business trajectory.
- Best for: Financial planning, inventory forecasting, and margin scenario modeling.
- Key Features: 6-month revenue & profit forecasting, growth rate projections, and detailed return-rate adjustments.
3. Amazon Tax Calculator
Clear, actionable insight into your tax burden. Most calculators only handle one piece of the puzzle. Ours handles three. Estimate your self-employment and income tax liability, calculate combined sales tax rates for any US state, and see your “Total Burden” after Amazon’s fees and tax layers are applied.
- Best for: Quarterly tax planning, understanding marketplace facilitator tax, and verifying net margin after tax.
- Key Features: Three-tab dashboard (Income Tax, Sales Tax, and Total Burden), US state-specific tax lookup.

Our interactive PPC audit template walks you through 34 critical checks across your campaign structure, bidding strategy, and search term hygiene. You’ll get a live health score and a prioritized fix list that tells you exactly what to optimize first.
