The Cost Calculator determines pricing for AI image upscaling based on image dimensions and resolution multipliers.

Pricing Structure

Base Costs

• Upsampler API: $0.04 per credit
• Credit calculation: 0.25 credits per megapixel
• Default markup: 200% (3x cost multiplier)
• Stripe minimum payment: $0.50

Resolution Multipliers

• 4x upscaling: 16x increase in total pixels
• 8x upscaling: 64x increase in total pixels

Calculation Methods

calculate_cost_detailed()

Returns comprehensive pricing breakdown.

Parameters

• $image_data – Array with width/height
• $resolution – Resolution multiplier (4x, 8x)

Returns

array(
    'input_megapixels' => 4.0,
    'output_megapixels' => '64.0MP',
    'credits_required' => 16.0,
    'upsampler_cost' => 0.64,
    'markup_percentage' => 200,
    'customer_price' => 3.84,
    'profit_margin' => 3.20
)

calculate_simple_price()

Returns customer-facing price only.

Parameters

• $image_data – Array with width/height
• $resolution – Resolution multiplier

Returns

• float – Final customer price

Price Validation

Minimum Price Enforcement

• Stripe minimum of $0.50 automatically applied
• Small image handling with appropriate scaling
• Error handling for invalid dimensions

Cost Components

1. Calculate output megapixels: (width × height × multiplier²) ÷ 1,000,000
2. Calculate credits needed: megapixels × 0.25
3. Calculate base cost: credits × $0.04
4. Apply markup: base_cost × (1 + markup_percentage/100)
5. Enforce minimum: max($0.50, final_price)

Configuration Options

Customizable Settings

• smi_markup_percentage – Profit margin control
• Upsampler cost per credit (constant)
• Stripe minimum payment (constant)

Resolution Support
