Divide your genuinely available baking hours by the hours each order really takes, then cut the result by 20% for the things that go wrong. For most solo home bakers with one household oven, that lands at four to eight decorated cakes a week — a lot fewer than the number you say yes to.
Capacity is the number nobody calculates until they’ve blown past it. The symptom is familiar: a great week on paper, finished at 3 a.m., with a cake you weren’t proud of and a customer who noticed.
The capacity formula
Weekly capacity = (available hours ÷ hours per order) × 0.8
The 0.8 is not pessimism. It’s the failed bake, the late delivery of your cream, the child with a fever, and the order that changes on Thursday.
Two inputs, and bakers get both wrong in the same direction — optimistically.
Step 1 — Count your real available hours
Not the hours in a week. The hours you can actually stand in the kitchen and work, after everything else that has a claim on you. Write down the specific windows:
- Weekday evenings, 8–11 p.m., after the kids sleep: 3 × 3 = 9 hours
- Saturday morning, 5–11 a.m.: 6 hours
- Sunday afternoon, 1–5 p.m.: 4 hours
That’s 19 hours — and it’s already an optimistic week. Be honest about the evening you’ll be too tired to use, and don’t count hours you need for the palengke run, messaging customers, or cleaning. Those are business hours too, just not baking ones.
Step 2 — Know each product’s real hours
Time yourself once. Almost every baker underestimates by 30–50%, because memory keeps the mixing and forgets the cleanup, the piping that didn’t work the first time, and the twenty minutes finding the right sprinkles.
| Product | Active hours | Oven time |
|---|---|---|
| Simple 8" cake, buttercream | 2.5 | 45 min |
| Decorated 8" cake, piped design | 4 | 45 min |
| Tiered / custom cake | 8–12 | 1.5 hrs |
| Dozen ensaymada | 2 | 25 min |
| Brownie tray | 1.5 | 35 min |
| 4 banana bread loaves (batch) | 2.5 | 1 hr |
Note the shape of that table: the tiered cake takes three to five times the work of a simple one. If it isn’t priced at three to five times the labor, it’s eating capacity you could have sold more profitably — the exact trap in is my home bakery actually making money.
Step 3 — The oven is a separate bottleneck
This is the constraint that catches people out. You can only work one pair of hands at a time, and you can only bake one oven-load at a time — and those two limits are not the same limit.
A household oven fits one or two 8-inch pans. Four decorated cakes due Saturday means four separate bakes plus cooling time before any of them can be frosted, and cooling can’t be rushed without ruining the frosting. Suddenly the binding constraint isn’t your energy — it’s a queue of pans.
- Count oven slots per day, not just hours. Six baking hours might only be four usable oven loads once you account for preheating and cooling.
- Bake the same product together. One oven session for all the ensaymada beats three.
- Split across days — bake Friday, decorate Saturday. Most cakes are better for it anyway.
Step 4 — Cut 20%, and put it in writing
Run the numbers for a typical week: 19 available hours ÷ 4 hours per decorated cake = 4.75 cakes. Times 0.8 gives you about 4 decorated cakes a week — or a mix, since not every order is a decorated cake:
| A realistic full week | Hours |
|---|---|
| 2 decorated 8" cakes | 8 |
| 1 simple 8" cake | 2.5 |
| 2 dozen ensaymada | 3 |
| 1 brownie tray | 1.5 |
| Buffer (20%) | 3.8 |
| Total | 18.8 of 19 hrs |
That’s a full week. Write the number on your fridge, because the fifth order never announces itself as the one that breaks you — it arrives as a nice message from someone you like.
When demand exceeds capacity
This is a good problem, and there’s exactly one first move:
- Raise your prices. If you’re turning work away every week, you’re priced below what the market will pay. Higher prices on the same capacity means more money and fewer 3 a.m. finishes. This is the answer bakers skip.
- Drop the worst-paying product. Look at profit per hour, not per order — the fiddly item that earns ₱90 an hour is stealing slots from the one that earns ₱300.
- Set batch days. "Ensaymada is baked Thursdays" turns scattered orders into one efficient session.
- Open pre-orders with a cut-off. Orders in by Tuesday for the weekend. Predictable capacity, better buying, no scrambling.
- Then consider a second oven or help — after the first four, not before.
"I’m fully booked that weekend — I have Saturday the 30th free po" is not lost business. It’s a customer who learns you’re in demand and worth planning around. The order you should fear is the one you accept while already full: it costs you sleep, quality, and sometimes the customer who got the rushed cake.

Know your number before the messages arrive. Capacity you’ve calculated is a boundary you can hold cheerfully; capacity you discover at 3 a.m. is just regret with frosting on it.
