About PB Digital Tools

PB Digital Tools provides fast, lightweight calculators for small businesses. We emphasize correctness and transparency: each tool includes formulas and worked examples so you can check the math.

Methodology

• Clear formulas with assumptions stated.
• UI validates inputs and explains edge cases.
• When third-party fees or holidays are involved, we link to primary sources.

Update cadence

We review fee assumptions and holiday lists periodically. If you spot an error, please contact us.
