This source is a three-slider arithmetic worksheet. Base earnings equal impressions divided by one thousand times the selected CPM. Its engagement bonus is the entered engagement percentage number times ten cents, added independently of impressions. This is the formula implemented here, not a verified social platform payout model. The source does not query an account, ad policy, eligibility, prices or revenue receipts. Interpret the sliders as assumptions rather than evidence of earnings. For one thousand impressions at a CPM of five dollars, the base is five dollars. Engagement entered as two gives a twenty-cent additive bonus and a total of five dollars twenty. Changing engagement to five gives fifty cents and a total of five dollars fifty. The two total bars share twenty pixels per dollar, making one hundred four and one hundred ten pixels. The engagement input is not applied as a percentage multiplier on the base. Every input updates the display and saves all three numeric values locally. Reload restores them. Reset returns to one hundred thousand impressions, CPM five and engagement two, then immediately recomputes and saves defaults again. Export downloads all inputs and computed base, bonus and total. The source joins locale-formatted numbers with commas without quoting cells, so a thousands separator can create extra CSV columns. Preserve the complete raw download and inspect its formatting before treating it as a structured dataset. No model or account integration is called.
