When you purchase Moneydance directly from our website, you're entitled to use the current version and (at a minimum) the next release.
For example, everyone who purchased Moneydance 2020 receives a free upgrade to Moneydance 2021.

Any further upgrades are discounted for you at 50%.

However, we never force upgrades or 'sunset' older versions of the program. You can continue to use the same version of Moneydance for as long as you wish.

You can enter your current license key into the 'Upgrading?' box on this page to check if an upgrade to the latest version is free or discounted.

If the upgrade is discounted, follow the "click here" link that is generated. You'll be taken to the checkout page where the discount will already be applied. Once you've purchased, you'll be sent a new license key via email.

If the upgrade is free, you can download the latest version from here. If prompted, you can enter your current license key to register the program.

If you purchased Moneydance from the Mac App Store or Microsoft Store, you should update the program via the relevant store directly.
