Net Profit Calculator
Generate a full income statement in seconds — gross profit, EBITDA, operating profit, net profit and net margin — with industry presets and a financial health score.
Summary
A Net Profit Calculator builds an income statement from revenue, COGS, operating expenses, depreciation, interest and tax. Net Profit = Revenue − COGS − OpEx − D&A − Interest − Tax. It also derives EBITDA (gross profit minus operating expenses, excluding D&A) and operating profit. Owners, accountants and investors use it to compare profitability across periods, against budget and against industry benchmarks.

Automated recommendations
- Gross margin of 34.6% is acceptable but can usually be lifted 2–4 points through better buying and shrink control.
- Net margin is 1.0% — thin. A 1-point lift in gross margin would more than double profit.
What is the Net Profit Calculator & Income Statement Generator?
The Net Profit Calculator is a full income-statement builder. You enter revenue, cost of sales and the main operating expense lines (labour, rent, utilities, marketing, other), plus depreciation, interest and tax — and it returns gross profit, EBITDA, operating profit and net profit, with each margin expressed as a percentage of revenue.
Industry presets seed the calculator with realistic cost structures for supermarkets, restaurants, cafés, hospitality, e-commerce, wholesalers, specialty retail and convenience. Adjust the inputs and watch a financial health score recalculate in real time.

Why this metric matters
Net profit is the only number the business actually keeps. Revenue, GP and EBITDA all matter, but net profit funds tax, debt, dividends and reinvestment. A retailer running healthy gross margin and strong sales can still lose money if operating expenses, interest or tax aren't disciplined — and the only way to see it is to build the full P&L.
EBITDA, the line above net profit, is what most buyers and lenders price the business off. Knowing both your EBITDA margin and your net margin tells you whether you have a trading problem (EBITDA) or a financing / capital problem (gap between EBITDA and net profit).
Formula
Gross Profit
Gross Profit = Revenue − Cost of Sales
Profit on products before any operating expense.
EBITDA
EBITDA = Gross Profit − Operating Expenses (excl. D&A)
Earnings before interest, tax, depreciation and amortisation — the trading-cash proxy buyers and lenders use.
Operating Profit (EBIT)
Operating Profit = EBITDA − Depreciation − Amortisation
Profit from operations after non-cash asset charges, before financing.
Net Profit
Net Profit = Operating Profit − Interest − Tax
The bottom line — what the business retains after every cost.
Net Margin
Net Margin % = (Net Profit ÷ Revenue) × 100
Net profit as a share of revenue. The single most cited profitability ratio.
Worked example
A neighbourhood supermarket reports $4.8m revenue and $3.6m COGS — GP $1.2m (25%). Operating expenses are $880k (labour $520k, rent $140k, utilities $60k, marketing $40k, other $120k) — EBITDA $320k (6.7%). Depreciation $90k → Operating Profit $230k. Interest $40k + Tax $48k → Net Profit $142k (3.0% net margin). Healthy for a single-site supermarket; the 6.7% EBITDA is the number a buyer would value the business off.
Real-world examples
Independent supermarket
$4.8m rev → 25% GP → 6.7% EBITDA → 3.0% net. Typical for single-site grocer.
Full-service restaurant
$2.1m rev → 68% GP → 9% EBITDA → 4% net. Prime cost discipline drives the spread.
Coffee shop
$650k rev → 78% GP → 14% EBITDA → 8% net. Labour 30% of revenue is the swing factor.
E-commerce DTC
$1.2m rev → 55% GP → 8% EBITDA → 4% net. Ad spend at 18% of rev keeps net thin.
Convenience store
$1.9m rev → 32% GP → 5% EBITDA → 1.5% net. Wages and rent absorb most of GP.
Specialty apparel
$900k rev → 52% GP → 11% EBITDA → 6% net. Mall rent is the largest opex line.
Bakery café
$780k rev → 72% GP → 12% EBITDA → 6% net. Pre-dawn labour drives the cost base.
Pharmacy
$3.2m rev → 28% GP → 7% EBITDA → 3.5% net. Front-end mix lifts blended margin.
Wholesaler
$8m rev → 18% GP → 4% EBITDA → 1.8% net. Volume-driven; net depends on receivables discipline.
Industry benchmarks
Net margin and EBITDA margin by retail / hospitality segment.
| Segment | Excellent | Average | Poor |
|---|---|---|---|
| Supermarket (independent) | ≥ 4% | 1.5–4% | < 1% |
| Supermarket (chain) | ≥ 3% | 1.5–3% | < 1% |
| Full-service restaurant | ≥ 8% | 3–8% | < 2% |
| Quick-service restaurant | ≥ 10% | 5–10% | < 3% |
| Coffee shop | ≥ 10% | 5–10% | < 3% |
| E-commerce DTC | ≥ 8% | 3–8% | < 1% |
| Convenience | ≥ 3% | 1–3% | < 0.5% |
| Specialty retail | ≥ 8% | 4–8% | < 2% |
| Wholesale | ≥ 3% | 1–3% | < 0.5% |
| Pharmacy | ≥ 5% | 2.5–5% | < 1.5% |
Net margins are highly format-dependent. Compare like-for-like and use EBITDA margin for cross-segment comparison.
Common mistakes to avoid
1. Reporting EBITDA as if it were net profit
How to avoid: EBITDA excludes depreciation, interest and tax. Always show net profit alongside EBITDA so the gap is visible.
2. Mixing one-off costs with trading expenses
How to avoid: Separate one-off items (restructuring, legal settlements, asset write-downs) from operating expenses to keep the P&L comparable.
3. Booking inventory purchases as COGS in the same period
How to avoid: COGS is the cost of goods sold, not bought. Adjust for opening and closing stock so margins reflect the period.
4. Forgetting depreciation on fit-out and equipment
How to avoid: Capital spend has to flow through as depreciation. Skipping it overstates operating profit.
5. Excluding owner's drawings from labour
How to avoid: If the owner works in the business, cost their time at market rate so net profit reflects an arms-length P&L.
6. Ignoring sales tax in revenue
How to avoid: Use net (ex-tax) revenue. Tax-inclusive sales overstate every margin ratio.
7. Treating credit-card processing fees inconsistently
How to avoid: Net payment fees against revenue (preferred) or include them under operating expenses — but always consistently.
8. Forgetting marketplace and platform fees
How to avoid: Amazon referral, Shopify payments, food-delivery commission — net these against revenue before measuring true GP.
9. Underestimating the effective tax rate
How to avoid: Use your actual effective rate (federal + state + local), not just the headline corporate rate.
10. Comparing net margin across segments without context
How to avoid: A 3% supermarket net margin and a 3% restaurant net margin tell very different stories. Always benchmark within segment.
