Plain formulas (so you don’t need an accountant for the basics)
All arithmetic uses simple subtraction:
Gross Profit = Total Revenue − Cost of Goods Sold
Net Profit = Gross Profit − Operating Expenses
Example calculation (digit-by-digit shown):
Revenue = ₹50,000
COGS = ₹30,000
Gross Profit = 50,000 − 30,000 = 20,000
Operating Expenses = ₹10,000
Net Profit = 20,000 − 10,000 = 10,000
So final: Gross Profit = ₹20,000, Net Profit = ₹10,000.
(Results in the UI are displayed with two decimal places for clarity.)
Examples (real-world)
Example A — Daily quick check
Revenue: ₹4,500
COGS: ₹2,500 → Gross = 4,500 − 2,500 = ₹2,000
OpEx: ₹900 → Net = 2,000 − 900 = ₹1,100
Example B — Monthly planning
Revenue: ₹300,000
COGS: ₹180,000 → Gross = 300,000 − 180,000 = ₹120,000
OpEx: ₹70,000 → Net = 120,000 − 70,000 = ₹50,000
Use these to see whether promotions, price increases, or cost negotiation are needed.
What the UI saves (history)
Each calculation saved as: Period + summary string (Revenue, Gross, Net).
History persists for the browser session (not saved to server). Clear it via Clear History.
Why it matters: reuse previous results when comparing days or checking similar promotional periods.
Practical tips for shop owners
Always include all direct costs in COGS (packaging, taxes on purchase if not reclaimable).
Group operating expenses into major items (rent, wages, utilities, marketing) for better later analysis.
Use Monthly mode to plan salaries, rent, and recurring costs; Daily mode for quick day-to-day health checks.
If Net Profit is low or negative, check whether COGS or Operating Expenses are the issue:
High COGS → negotiate with suppliers, buy in bulk or adjust retail price.
High OpEx → reduce utilities or staffing inefficiencies, renegotiate rent if possible.
Record the rate/date used when converting foreign currency costs (if COGS in USD etc.), so accounting matches later.
Edge cases & validation
Revenue must be > 0. Tool will warn if revenue ≤ 0.
Expenses may be zero (allowed), but not negative. Negative values will be rejected.
This is a simplified estimator — it does not calculate tax (GST/VAT), depreciation, loan interest, or amortization. For tax-ready P&L use your accountant or accounting software.
Large differences between gross and net profit may signal missing expense lines or mis-recorded COGS.
Quick troubleshooting
Modal won’t open: ensure browser has Bootstrap JS enabled; refresh the page.
Wrong numbers: double-check the input fields, correct period selected (daily vs monthly).
History cleared unexpectedly: history is stored in the browser session — closing/incognito may clear it.
Need persistent records: export or copy results into your accounting system; this tool is for quick estimates.
Example 10-minute action plan (what to do now)
Open the estimator, select Monthly.
Enter last month’s revenue and known COGS and OpEx. Click Calculate.
If Net Profit < target, decide one action: increase price by X%, reduce supplier cost, or cut one expense.
Save the calculation details in your shop notes or accounting file for comparison next month.
Who should use this and how often
Shop owner / manager: run after each trading day or at least weekly.
Accountant / bookkeeper: use as a quick check before formal bookkeeping.
Store supervisor / shift manager: daily checks to monitor promotions or special events.
Summary (one-line)
