Salt Calculator

Choose a Salt Planning Task

Plan salt purchase quantities, pack counts, stock cover and shopping cost from your measured household use. This tool does not recommend sodium intake, diagnose a health condition or determine a recipe’s seasoning.

Choose quantity planning for people and days, purchase costing for a known quantity, stock duration for supply days, whole packs for package counts, or waste valuation for a separate cost scenario. Use the family ration basket calculator for several grocery categories in one order.

Keep the Purchase Basis Consistent

Fine, coarse, iodized and rock salt can have different pack weights and prices. Keep use, stock, pack quantity and price on the same purchased-product basis, and use a separate row when products or quotations differ.

Measure Household Salt Use

Measure the salt container at the start and end of a representative period, adding any refill weight before calculating use. Divide the household amount used by the number of days and people. Treat the result only as a shopping input.

Enter planning days separately and recount the stock you judge usable.

Choose Units and Price Basis

Use kg for bulk quotations and g for smaller packets. One kilogram equals exactly 1,000 grams. A spoon is a volume measure, so weigh the salt used with your usual spoon instead of assuming a universal mass.

Selected Unit pricing means the price of one current unit. Whole Pack pricing means the entire price of the entered pack quantity. Set that quantity before entering its price. Changing pack size leaves a whole-pack quote for you to review.

The NIST conversion tables support the exact kg/g relationship. No density, average item weight or preparation factor is applied.

Salt Quantity, Cost and Stock Formulas

• Planned use: people × daily use per person × days.
• Shortage: max(planned use − usable stock, 0).
• Whole packs: round up(shortage ÷ quantity per pack).
• Purchase: packs × pack quantity, or loose shortage.
• Goods cost: purchased quantity × matching unit price, or packs × pack price.
• Order total: goods subtotal + delivery once.
• Stock cover: existing stock ÷ household daily use.
• Waste value: goods cost × waste percentage ÷ 100.

Zero daily use has no finite depletion date. Waste is within goods cost, not another charge. The waste task values a known purchase and excludes delivery.

Worked Monthly Salt Example

The fictional example uses four people, 0.004 kg each per day and thirty days: 0.48 kg planned. Subtract 0.08 kg stock to leave a 0.4 kg shortage. One 0.5 kg pack at PKR 100/kg costs PKR 50 and leaves 0.1 kg surplus. Add PKR 50 delivery once for a PKR 100 total.

A five-percent waste scenario values PKR Rs 2.50 within goods cost. It neither orders replacements nor changes the total.

Understand Buying Rules and Surplus

Packs and increments round upward to the entered size. Loose mass keeps the shortage. Surplus is purchased quantity minus shortage, not an extra fee. Compare actual quotations when different packages have different unit prices.

Weekly Orders and Existing Stock

Two people at a fictional 0.004 kg each per day use 0.056 kg in seven days. Subtract 0.006 kg stock to leave 0.05 kg. One 0.1 kg pack at PKR 100/kg costs PKR 10 and leaves 0.05 kg surplus.

The stock example divides 0.16 kg by a household rate of 4 × 0.004 kg daily, giving ten arithmetic days. It is a depletion estimate, not health guidance.

Recalculate separate orders when stock, prices, packs or delivery differ. Delivery applies once to the entered order, not automatically to every trip in a month.

Prices, Currency and Report Precision

All example prices are fictional. No official rate or shop quotation is fetched. PKR is the default, then INR, USD, GBP, EUR, SAR and AUD. Conversion uses the saved indicative reference dated 4 November 2026, not live prices, bank quotes or local purchasing power.

Choose the currency and enter the actual local quotation for your purchase. Monetary inputs, delivery, budgets and results convert together with exact internal fractions. Final money rounds half-up to two decimals.

Copy and print preserve precise unit prices, including exact fractions where needed. CSV records units, pack size, rule, price basis, currency and waste percentage. Quantities display up to nine decimals; stock cover to three. Internal arithmetic remains exact.

Input Limits and Important Boundaries

Enter one to one hundred people, zero to 366 planning days and up to fifty rows. Quantity inputs are bounded at one million kg; daily use at one hundred base units per person and money at equivalent PKR one trillion. These are input-validation limits, not dietary recommendations or caps on computed totals.

Blank required fields, negative quantities, zero required pack sizes and waste above one hundred percent are rejected. Zero price means free goods. Use the net weight on the label for a sealed pack.

Stock cover does not assess handling, temperature, freshness, ripeness, expiry or safety. Do not treat arithmetic supply days as a safe-storage period. Prepared yields, nutrition, recipe servings, medical advice and government eligibility are outside scope.

Save or Share Your Plan

Use Copy Summary, Print, CSV or Copy Link after a valid result. Invalid required inputs block stale exports. Shared links encode entered values; anyone with the link can read them. Omit personal details from item labels.

Calculations run in your browser. Session storage remembers only currency, not the list. Save a report or link to retain inputs. Local-file links need the same calculator file.
