How Much Does 20 Minutes Worth of Fireworks Cost?

A 20-minute consumer fireworks show, the kind put on in a private backyard or field using retail products, typically costs between $500 and $1,000 in product, depending on what you buy and how you pace the show. A tighter budget of $200 to $300 can produce a 20-minute show if filled with slower-burning fountains, ground items, and modest aerial cakes. A $1,500 to $2,500 budget produces a noticeably heavier show with more aerial product, bigger shells, and a strong finale. A professional licensed display of the same duration costs significantly more, typically $5,000 to $15,000, because it uses a different product category entirely.

The most important variable is not total spend but product selection and pacing. The same $800 budget produces a 12-minute show packed with 500g finale cakes or a 25-minute show built around smaller repeaters, ground items, and artillery shells fired one at a time. Understanding how individual products contribute to show duration is the key to budgeting accurately.

How Long Individual Products Actually Burn

Most people significantly underestimate how quickly fireworks consume budget when purchased without a runtime framework. Knowing the burn time of each product category lets you plan show duration before you spend anything.

200-Gram Repeating Cakes

200-gram aerial repeating cakes, the mid-range aerial product available at most retail fireworks stores, typically produce 45 to 90 seconds of aerial output per unit. A cake with 25 shots firing at roughly 2-second intervals runs about 50 seconds. A 36-shot cake with slightly longer intervals can stretch to 75 seconds. At an average of about 60 seconds per unit, you need roughly 20 cakes to fill 20 minutes with 200g aerial product, with no gaps between them. Budget $10 to $25 per unit for 200g cakes, putting a 20-unit purchase at $200 to $500 before any other product.

500-Gram Finale Cakes

500-gram finale cakes are the heaviest consumer aerial product available at retail. They produce 60 to 120 seconds of dense, high-volume aerial output per unit, but they burn fast and loud, which is why they are designed for finales rather than the body of a show. Using 500g cakes as your primary fill product is the most expensive way to build 20 minutes of show time. At $30 to $80 per unit and 60 to 90 seconds of runtime, you would need 15 to 20 units to cover 20 minutes, costing $450 to $1,600 in 500g product alone. Most experienced buyers use 500g cakes selectively: two to four units for the finale, with less expensive product filling the rest of the show.

Artillery Shell Kits

Reloadable artillery shell kits, also called mortar kits, give the operator precise control over show pacing. Each shell fires individually and produces 5 to 8 seconds of aerial effect. A 12-shell kit, fired at deliberate 15-second intervals between each shot, produces roughly 5 minutes of show time from a single kit. A 60-shell kit fired at the same pace produces 25 minutes. Artillery shells are one of the most cost-efficient ways to build a long consumer show: kits range from $20 for 12 shells to $80 for 60 shells, and the pacing is entirely in your hands. Slowing down between shots is free show time.

Roman Candles

Multi-ball Roman candles, typically 10 to 20 shots per candle, produce 30 to 90 seconds of aerial output per unit depending on shot count and interval. They are inexpensive relative to cakes ($3 to $15 per candle), which makes them effective fillers between heavier aerial product. Holding a candle and firing it as a handheld item creates a different visual experience from ground-launched product and adds variety to a show without significant budget impact.

Fountains and Ground Items

Fountains are the most time-efficient product for stretching show duration on a limited budget. A quality fountain burns for 60 to 180 seconds and costs $5 to $20. Multiple fountains burning simultaneously create a wide ground-level visual that fills show time while preserving aerial budget for higher-impact moments. Ground spinners, crackling items, and color-changing ground effects serve the same pacing function. Experienced show builders use ground items deliberately during the opening and mid-show to let the audience settle before the aerial sequence begins.

What Different Budgets Actually Buy

$150–$250 - Light 20-minute show: 4–6 small 200g cakes, 2–3 fountain clusters, 1 artillery kit (12 shells),

  assorted Roman candles and ground items. Thin on aerial content. Works for small yards and young audiences.

 

$400–$600 - Solid 20-minute show: 8–10 200g cakes, 2 artillery kits (24–36 shells), 4–6 fountains,

  Roman candles, sparklers, 1–2 500g finale cakes. Good aerial presence with a clear finale moment.

 

$800–$1,200 - Full 20-minute show: 12–16 200g cakes, 2–3 artillery kits (60+ shells), 1 case of fountains,

  multiple Roman candle sequences, 3–4 500g finale cakes. Consistent aerial output with a heavy finish.

 

$2,000–$2,500 - Premium 20-minute show: Heavy aerial throughout, multiple 500g cake sequences,

  large-shell artillery kits, coordinated ground and aerial finale. Approaches semi-professional visual density.

 

Consumer Fireworks vs Professional Display: The Cost Gap

A professional licensed fireworks display of 20 minutes, the kind put on by a pyrotechnic company for a municipality, stadium, or large private event, costs between $5,000 and $15,000 for a basic show, with elaborate productions running $25,000 or more. The cost difference is not primarily markup. It reflects a fundamentally different product category.

Professional displays use Class B fireworks: shells ranging from 3 to 12 inches in diameter, launched from steel or HDPE mortars at heights of 200 to 1,200 feet. These products are not available to retail consumers and require licensed pyrotechnician operators, site safety plans, and fire marshal permits. The visual output,  shell diameter, burst size, height, and duration is categorically different from consumer Class C products. A professional 3-inch shell produces a burst roughly 150 feet in diameter. The largest consumer aerial product produces a burst roughly 75 to 100 feet in diameter. Both are impressive at their respective scale; they are simply different products for different contexts.

The Variables That Change Everything

Two variables determine whether a given budget produces 10 minutes or 30 minutes of show: pacing and product mix. Pacing is the time you build into the show between items. A show fired with no gaps, one product starting immediately as another finishes, burns through product at maximum rate. A show fired with 5 to 10 second gaps between items, occasional pauses for crowd reaction, and deliberate slow-build sequences in the opening can stretch the same product inventory by 30 to 50 percent.

Product mix is the ratio of high-burn-rate aerial product to lower-burn-rate filler. A show built primarily around 500g finale cakes will be visually intense and brief. A show built around artillery shells, fountains, and 200g cakes with two or three 500g units saved for the finale will run longer, feel more structured, and often read as more professional to an audience because it has clear movement and a genuine climax.

Getting the Most From Your Budget at FireworkStore

The most effective way to plan a 20-minute show on any budget is to start with the finale and work backward. Decide how much you want to spend on the final two to three minutes,  typically the heaviest aerial and 500g product, then allocate the remaining budget across the body of the show using a mix of artillery shells, 200g cakes, Roman candles, and fountains. FireworkStore staff can help you map out a specific product list for your intended show duration, space, and budget so that what you buy matches what you are trying to build.
