how many Robux for 20 reais
With R$ 10 or R$ 20 the dollar math gives $1.85 and $3.70, and neither reaches the smallest pack on sale ($4.99, about R$26.95). In theory they would yield a few hundred Robux; in practice the purchase cannot happen.
Theoretical: the amount does not reach the smallest pack.
Also under the $4.99 of the smallest pack.
R$6.95 short when starting from R$ 20.
It depends on which side you are on. Buying costs $0.0100 (web and gift cards) to $0.0125 (app) per Robux. Cashing out via DevEx pays a creator $0.0038 per earned Robux: 100,000 earned Robux become $380. Only eligible creators with at least 30,000 earned Robux can cash out.
Because proportional math is what most people look for as a price reference. The tool flags with an asterisk the amounts below the smallest pack to make clear they are arithmetic only.
In the packs we checked, $4.99, about R$26.95 in reais. The on-screen price can differ slightly by region and tax.
In the sources we checked, the payment method does not change the pack's Robux; it may change the final amount in reais. Compare the total shown at checkout before confirming.
The same 296 Robux, if earned and cashed out via DevEx, would be worth $1.12.
Notice the gap: buying Robux costs far more per unit than cashing them out via DevEx, that spread goes to the platform.
An estimate. DevEx rates, purchase prices and subscription terms change and vary by region; always check the official Roblox page before deciding.

† Under 30,000 earned Robux there is no cash-out; the figure is only the equivalent value. Buying prices are proportional to the reference pack, not the checkout total, which charges whole packs. Web values are estimates: only some packs were confirmed.
