Donation Impact Calculator

What This Calculator Counts

A donation on a live stream passes through three hands before it becomes money a streamer can spend: the viewer, the payment processor, and the platform that hosts the tip page. This calculator walks one gift down that path and reports the two numbers a streamer watches, the cash that lands after fees and the distance the gift moves the goal bar.

Four assumptions sit under the math, and each one is a field on the calculator. The gift is what the viewer types, before any deduction. The processor charges a percentage plus a flat fee on every transaction. The platform may take a percentage, and that field starts at 0 because Streamlabs states that it takes no cut of tips as of October 2026. The goal bar and the leaderboard both count the gift at face value rather than the net.

Three things sit outside the model. Chargebacks can pull money back weeks later, currency conversion adds a percentage when viewer and streamer hold different currencies, and payout timing decides when a balance turns into spendable cash. None of them changes the arithmetic here, and all three change what reaches a bank account.

The Fee Stack on a Live Donation in 2026

The processor takes its cut first, and the cut has two parts: a percentage of the gift and a flat charge per transaction. Streamlabs documents the card rate as 2.9% plus $0.30 and says it takes no share of tips, so on that route the processor fee is the only deduction. PayPal's published fee schedule for donations lists 2.89% plus $0.49, with a confirmed charity rate of 1.99% plus $0.49 for organizations that qualify.

On a $20 gift the card route costs 20 x 0.029 = 0.58 in percentage fees plus 0.30 flat, which is 0.88. The streamer keeps 19.12, or 95.60% of what the viewer sent. The table runs the three routes at the same gift size.

The flat charge is the part that changes behavior. A percentage scales with the gift and a flat fee does not, so the flat fee weighs heaviest on small amounts. Rates also vary by country and card type, which is why the calculator keeps a custom option open: enter the numbers your own dashboard shows and the rest of the page still works.

A $20 Gift, Step by Step

Take a stream with a $500 goal, $320 already on the bar, and a viewer who sends $20.

The money. The processor keeps 0.88, so 19.12 reaches the streamer. Nothing else comes off on the card route.

The bar. 320 + 20 = 340, which is 340 / 500 = 0.68, or 68.0% of the goal. The bar has 160 dollars left to fill, and at 20 dollars a gift that is 8 more gifts of the same size.

The leaderboard. The top donor sits at 100 dollars, so this gift lands 80 dollars behind and does not touch the top slot.

The full run. Nine gifts of 20 dollars carry the bar from 320 to 500, since 9 x 20 = 180 and 320 + 180 = 500. Those nine gifts move 180 dollars across the bar and leave 172.08 in the account, because 9 x 19.12 = 172.08. The 7.92 gap between the two figures is the price of collecting in small pieces.

Why $1 Gifts Lose a Third to Fees

Run the card route across gift sizes and the flat charge dominates the small end. A $1 gift pays 0.33 in fees, which is 33.0% of the gift. A $3 gift pays 0.39, or 13.0%. By the time a gift reaches 20 dollars the fee is 4.4%, and at 250 dollars it is 3.0%.

The pattern is mechanical. 1 x 0.029 = 0.029, plus 0.30 rounds to 0.33, and 0.33 out of a dollar is a third of the gift. The same 30 cents on a 250 dollar gift is one eighth of one percent, so only the percentage fee shows.

Two habits follow. A viewer with a small budget can send 10 dollars once instead of 1 dollar ten times, which cuts total fees from 3.30 to 0.59 on the same 10 dollars. A streamer can encourage monthly tipping, where five separate 1 dollar gifts cost 5 x 0.33 = 1.65 in fees while one 5 dollar charge costs 0.45.

Same Bar, Different Balance

Two hundred dollars of gifts is two hundred dollars on the bar no matter how it arrives. What changes is the balance, because the flat fee repeats with every transaction.

Four 50 dollar gifts keep 193.00, twenty 10 dollar gifts keep 188.20, and the 4.80 spread is fee arithmetic on an identical total. The bar cannot tell the difference.

This is the trade behind a minimum tip. A higher minimum raises the average gift and cuts the number of transactions, which lifts the net for the same bar progress. It also shrinks the pool of people willing to give, and that trade is a read on the audience rather than a math problem.

Goal Bars and Leaderboards Count the Gift

Most goal widgets, including the Streamlabs Tip Goal, add the amount the viewer entered. The bar therefore moves at gross speed while the bank account moves at net speed, and the two drift apart as the goal fills.

Plan in gross when the number on screen is the promise, and plan in net when the money is the promise. A goal to buy a 500 dollar microphone needs more than 500 dollars of gifts: at 20 dollars a gift it needs 27 gifts, since 27 x 19.12 = 516.24, while 26 gifts leave 497.12.

The table shows the closing stretch from 340 to a 500 dollar goal, where 160 dollars are still missing.

Leaderboards read the same way. Rankings compare the amounts viewers sent, so a 100 dollar gift ties a 100 dollar top donor and does not pass them. Ties are common at round numbers, and many dashboards break them by who arrived first.

Charity Streams: Where the Money Lands

A charity stream moves the same money to a different endpoint. When the charity holds a confirmed charity rate with PayPal, the deduction on a 100 dollar gift is 100 x 0.0199 = 1.99 plus 0.49, which is 2.48, so 97.52 reaches the charity. Through the standard donation rate the same gift costs 2.89 plus 0.49, which is 3.38, leaving 96.62. The charity rate is worth 0.90 on a 100 dollar gift.

Streamlabs Charity runs as its own route with its own receipting, and the standard tip page takes no platform cut, so on either path the processor fee is usually the only deduction between the viewer and the cause.

Tax treatment is where the paths split. A tip to a streamer is a payment for entertainment: it counts as income to the streamer and gives the viewer nothing to deduct. A gift made directly to a qualified 501(c)(3) can be deducted by a viewer who itemizes, and IRS Publication 526 (2025) sets out which organizations and which records qualify. Money that reaches a charity through a streamer's tip page often fails that test because the streamer receives it first, so confirm the route with a tax preparer before you claim anything.

Planning a Goal You Can Hit

Work backward from the number you need. With a percentage fee and a flat fee, the gross that nets a target is (target + flat) / (1 - rate). For 500 dollars on the card route that is (500 + 0.30) / 0.971 = 515.24, so a single gift of 515.24 nets 500.00 after a 15.24 fee.

Small gifts need more than that formula suggests, because the flat fee repeats. Twenty-seven 20 dollar gifts collect 540 dollars and pay 540 x 0.029 = 15.66 in percentage fees plus 27 x 0.30 = 8.10 in flat fees, which leaves 516.24. The same target costs 540 dollars of gifts in 20 dollar pieces and 515.24 in one piece.

Set the goal at the gross figure that matches the plan, and put the net in the overlay text when the money is earmarked for a bill. A bar that reads 500 next to a balance of 497.12 invites a conversation nobody wants mid-stream.

The calculator above makes that check quick: enter the gift size you expect, read the net and the gifts still needed, then adjust the goal until the two numbers agree.
