Input Cost Inflation Impact Calculator
Estimate how overall input cost inflation changes total costs, profit, and margin using your current cost structure.
A fast way to estimate how input cost inflation impacts total costs, profit, and margin using your current annual revenue and cost base.
Total annual sales.
Raw materials, components, fertilizer, fuel, etc.
Labor, overhead, rent, logistics, admin, etc.
Applies to your total cost base (materials + other costs).
Costs
Current: $780,000
New: $842,400
Increase: $62,400
Profit & margin
Profit: $420,000 → $357,600
Profit change: -$62,400
Margin: 35.00% → 29.80%
Break-even check (simple)
Revenue needed to break even: $842,400
Extra revenue needed (if any): $0
Assumes you don’t change prices or volume. Use this as a quick stress-test baseline.
Tip: Try multiple inflation scenarios to understand your margin sensitivity.
How it works
- Total costs = material/input costs + other costs.
- New costs = total costs × (1 + inflation%).
- Profit = revenue − costs (margin = profit ÷ revenue).
- Break-even revenue = new costs (profit = 0).
FAQ
Does inflation apply only to materials?
In reality it varies. This tool applies inflation to the whole cost base for a quick estimate. If you want “materials only,” set other costs inflation to 0 in a more advanced tool.
What if I pass costs to customers via price increases?
This tool assumes revenue stays constant. Pair it with a pricing pass-through calculator for that scenario.
How to use this input cost inflation impact calculator
- Enter annual revenue and current total costs.
- Break costs into material costs and non-material costs (optional but recommended).
- Enter an input cost inflation percentage to apply to the cost base.
- Review the change in profit and margin.
Example
A business has $1,200,000 revenue, $780,000 total costs, and expects 8% input cost inflation.
- Current profit = 1,200,000 − 780,000 = 420,000
- New costs = 780,000 × 1.08 = 842,400
- New profit = 1,200,000 − 842,400 = 357,600
- Margin falls as costs rise
