Coffee Latte Factor.

Coffee shop vs home brew calculator quantifies daily coffee habit cost. 7 cafe drinks/week × 4 = 1,456/year vs 7 home drinks × 0.50 = 182/year = 1,274 annual savings. 100k savings over 30 years. The Latte Factor: small daily habits compound to significant wealth.

Example: 7 cafe drinks/week (one daily) at 4 each = 28/week = 1,456/year. Same 7 home brews at 0.50/cup = 3.50/week = 182/year. Annual savings 1,274. Invested at 7% over 30 years: 125,000+ wealth from this single change. The famous Latte Factor in action.

Coffee economics: (1) Cafe latte/cappuccino 3.50-5.50 chains). (2) Independent specialty coffee 4-6. (3) Home brew machine costs: press 20-50, drip 30-100, espresso 100-2,500. (4) Coffee beans 15-30/kg = 0.30-0.60 per cup. (5) Milk/sugar additions 0.10-0.20. Home brew with quality beans matches cafe quality at fraction of cost. Best home setup: pour-over (30 + 25 grinder + 18 kettle + 20 beans monthly = 63 setup + 20/month). Pays for itself in 4 weeks of one cafe visit. Sustained habit creates significant savings.

Quick example

With cafe drinks per week of 7 and cafe cost per drink of 4 (plus home drinks per week of 7 and home cost per drink of 0.5), the result is 1,274.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Cafe Drinks per Week, Cafe Cost per Drink, Home Drinks per Week, and Home Cost per Drink. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.

What's happening under the hood

Annual savings = (cafe weekly cost - home weekly cost) × 52. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why see the number at all

Small recurring spending is invisible by design — every individual transaction is forgettable. Compounded over years, the total often surprises. Seeing the figure doesn't mean you typically need to cut the spending; it just makes the trade-off conscious.

What this doesn't capture

The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
