A currency conversion ratio is the exchange rate between real-world money and a platform's virtual currency, or between two virtual currencies. It sets how much in-app currency a user receives for a given amount of value, for example one dollar of offerwall revenue converting to 100 gems. Every reward economy runs on one of these ratios, whether the team has tuned it deliberately or inherited a default.

How it works

The ratio maps value the publisher earns onto currency the user receives. When a user completes an offer worth a dollar of revenue, the conversion ratio decides whether that becomes 50 gems, 100 gems, or 500. The publisher keeps the difference between what the offer paid and what the reward cost to grant, so the ratio is effectively the margin dial on the whole reward loop.

Why it matters

The conversion ratio is a balancing act. Set rewards too low and users feel shortchanged and disengage; set them too high and you erode your margin. The right ratio keeps rewards feeling generous while protecting revenue. Because it touches both sides at once, a small change here can move engagement and profit in opposite directions, which is why it deserves testing rather than a one-time guess.

It varies by market

Value differs by geography, so a well-tuned economy uses different ratios by region. A gaming app with users in Asia and North America will often run a different currency ratio for each, because the same offer can pay very different amounts in each market and users judge generosity against their local sense of value.

Conversion ratio vs. hard currency pricing

The conversion ratio governs how earned value becomes currency; your hard currency store price governs how purchased money becomes currency. The two need to stay in sensible proportion. If completing an offer hands out gems far faster than buying them ever could, you undercut your own IAP economy, and if it feels far stingier than paying, users see the reward as worthless. Tuning both together keeps earning and buying in balance, so the offerwall complements your store rather than cannibalizing it.

Tuning it on an offerwall

On an offerwall, the conversion ratio directly shapes how completing an offer feels to the user and how much you keep. Getting it right is one of the levers monetization partners like RevU help publishers tune, so rewards drive engagement without giving away margin. Because offerwall payouts vary by offer and by region, the ratio is rarely a single global setting; it is a set of values kept in step with what each segment of users is actually worth.

Common misconceptions

• That a more generous ratio always lifts engagement. Past a point it only trains users to expect rewards while cutting your take.

• That one global ratio fits every market. It usually leaves money on the table in some regions and overpays in others.

• That the ratio is set once. Offer values and user behavior shift, so it needs revisiting.
