Dynasty fantasy football tools: trade calculator, rankings, trade finder, season simulator
Connect your Sleeper leagues and Smash sets your lineups, sends your trades, and catches the moves you would miss.
Cancel any time, in two taps. No phone call, no hoops. You keep access to the end of the month.
Grade a trade in one tap. No account needed.
Add at least one asset to each side to get a verdict. Values are the public superflex set; the full calculator uses live values and your league's exact settings.

How it works
Three steps. One of them is yours.
Your Sleeper username. No password, nothing to install. Every league you're in shows up in under a minute — ESPN, Yahoo, FFPC and MFL import too.
Lineups set, waivers ranked, trades found and sent, a backup subbed in when a starter's scratched. Across every league, while you're at work or asleep.
Fewer zeros in your lineup, better trades, waiver adds before your league-mates notice. And a creator one message away when you want a second opinion.
Other tools grade your team. These run it.
Connect your leagues once. Everything below works across all of them, and the VIP tools act on Sleeper for you.

What members say
In their words.
Members earn Smash Points for rating Smash Accept, whatever the rating. These are reviews they chose to share.
“Trade finder giving ideas for trades is great”
“Trade calc is the best on the internet and really love the ask a creator aspect of it as well.”
“The trade finder has found me several trades (after some inspiration from the PODs) that were accepted. The new feature for suggestions have also helped, turned a competing team's injured Dart into Lawrence plus within an hour. Great s**t!”
“The trade calculator is something that is very useful when I want to confirm my thoughts on a deal.”
“This stuff rocks!”
“Really like all the features that I have on this. Rankings of positions per each team is great to look for trades.”
“The trade calculator has helped me get the most out of my rebuilding process when it comes to comparing player values and what the right amount of draft capital coming back to me is. I also love the Teams page so I can see who easy trade targets are based off their weaknesses and needs. It also helps me see where I need improvement in the rebuild and areas of focus for me in the draft.”
“Love the calculator and that it adjusts based on the quality of the offer. Line- up optimizer is nice for when you are in so many leagues. A trade finder that sends trades for you from the site is nice when you are trying to offload assets.”
“Was skeptical at first. But I have loved the inbox tool & creating trades on the site. I’ve gotten tons of trades done this week.”
“I’ve ran hundreds of trades through this app. I think the most valuable thing and what’s set it apart from all other calculators is that you’re able to simulate your season, so a trade that might not seem fair, or you might be giving up a little bit more at the time when you simulate the season, you see how much more it helps in the long run, and that can dictate your decision instead of just a standard number that you look at this trade talk is a smash except cowbell🔔🔔🔔🔔”
“Love using the Trade Calculator to assess trades going down and getting a realistic gauge as to what they are worth”
“Excellent site. Use it daily”

Frequently asked questions
Is Smash Accept free?+
The trade calculator is free with an account: dynasty and redraft, live values, your league's format, no card, and a few new trades a day (unlimited on any plan). The cross-league tools are part of paid plans. See what each membership includes.
Is $24.99 a lot when other tools are free?+
The free tools show you values. Smash VIP acts on your real leagues (Auto-Sub, one-click lineups, trades sent through Sleeper) and includes unlimited direct questions to the creators, which cost $1.49 and up each without it.
Can I cancel any time?+
Yes. Account → Billing → Cancel, confirm, done — two taps. No phone call, no chat with a retention team, no offer you have to click past. Your access runs to the end of the period you paid for, and you can come back whenever you like.
Does Smash Plus include trade advice from the creators?+
No. Plus includes the tools. Creator questions are pay per question on Plus, from $1.49, and unlimited direct creator chat is included with Smash VIP.
What if I sign up and never log in?+
Connect your leagues once and the Tuesday waiver email, the lineup checks and (on VIP) Auto-Sub keep working whether you log in or not. You can cancel anytime from your account page.
Which platforms are supported?+
Sleeper connects directly with just your username. ESPN, Yahoo, FFPC and MFL leagues import too. The tools that act on your league, like Auto-Sub and sending trades, work through Sleeper.
Does it work on my phone?+
Yes. The whole site is built mobile-first, including connecting Sleeper and hunting trades from your phone.
