I Can Save 10% by Buying Six Months of Candle Raw Materials at Once — How Do I Compare the Saving Against Cash Being Locked in Inventory?

The month you are multiplying by six

The example business makes 400 container candles a month: 200 g each at an 8% load, in five scents of 80 candles each. Wax is Luxury Soy Wax Chunks at ₹599.00 a kilo; each candle takes one Eco Candle Wicks Thin C1 (₹5.90) and one White Matte Glass Jar (₹70.80). Oils are priced at their 1 kg rates. Plan 3–5% extra for pour loss and test burns — a working assumption left out of the table to keep the comparison clean.

So the offer means writing one cheque for ₹5,89,469.53 instead of ₹1,09,161.02 a month. Across the six months you pay ₹65,496.61 less. Fragrance is 32% of the bill, wax 40%, jars 26% and wicks 2%. Those shares matter later, because the risk is not spread evenly across them.

What 10% really earns

There are two correct ways to compare a discount with locked-up cash. They give the same verdict, so use whichever you find easier to explain to a business partner.

Method 1 — the implied monthly return

Without the offer you pay one month's bill each month. With it you pay 6 × 0.9 = 5.4 months' bill in month 1, then nothing for five months. So in month 1 you pay 4.4 months' bill extra (₹4,80,308.51), and in each of months 2–6 you pay one month's bill less (₹1,09,161.02). The monthly rate at which those five savings are worth exactly the extra month-1 payment is 4.42%. It does not depend on the size of your bill — any 10%-for-six-months offer paid up front has the same implied return.

Two lessons from the table. Longer commitments at the same discount earn less per month, because the cash waits longer for its return. And a 5% six-month offer earns about half as much as the 10% — which may be no more than your own cost of money. If you are offered several versions, the shortest period at a given discount is usually the better return.

Method 2 — the holding charge

Charge a monthly holding rate on the extra stock you carry. Buying monthly, your average stock is about half a month's bill. Buying six months at 90%, your average stock over the period is about three months' bill at 90%. The extra average is ₹2,40,154.25, held for six months. Charge it at an example rate and compare with the ₹65,496.61 saving:

At an example 1.5% a month the offer nets ₹43,882.73. At 3% it still nets ₹22,268.85. Around 4.5% a month the saving and the holding charge meet — close to Method 1's answer, as it should be. The verdict before risk: for most small businesses, 10% for six months beats the cost of money. The rest of the page is about the things that can reverse that verdict.

What the return does not include

A scent stalls. Suppose — as an example — Bergamot Amber stops selling at month three. Three months of it, ₹18,790.27 at the discounted price, is left on the shelf. If you can recover 30% through wax melts or testers (an example salvage figure), you lose ₹13,153.19. That single event wipes out 20% of the six-month saving.

Sales come in below plan. If the business sells 25% fewer candles than planned, six months of stock lasts 8 months. The cash waits a third longer, which cuts the implied return, and any scent that was going to fade has longer to do it. A six-month order should be based on the last three months' actual sales, not on the plan.

Cash runs short at the wrong time. The upfront payment is ₹5,89,469.53. If paying it leaves you unable to buy festive jars, gift boxes or extra fragrance for Diwali — 8 November 2026, 43 days from today — you will end up placing emergency orders at full price, or turning down festive sales.

Take it on some materials, not all

Most offers can be negotiated by material. The best version for most candle businesses is to commit six months on the shared, non-perishable inputs and keep fragrance flexible.

Taking the offer on wax, wicks and jars only saves ₹44,859.84 over six months — 68% of the full saving — while every rupee committed goes into materials that every candle uses. Month 1 then costs ₹4,38,133.18 (six months of the shared materials plus one month of oil), against ₹5,89,469.53 for the full offer. The fragrance you keep flexible is exactly the part of the bill most exposed to a stalled scent or a festive swing.

The materials in the example

The wax that makes up the biggest share of the six-month order, and two of the scents — the largest oil line, and the lowest-cost one.
