How would you manage your combined finances as a DINK to hit financial independence? Any advice on investing stratgey and savings?

Communicate and have common goals.

We’re in a similar DINK setup, and what worked for us is treating liquidity tiers as part of our FI roadmap.

We split our cashflow into:

• Core investing – DCA into ETFs (VOO, IWDA) via a low-cost broker.
• Mid-term buffer – parked in something like Tiger’s Cash Boost Account. It gives better yield than bank savings but stays liquid in case we want to pounce on market dips or use it for near-term goals.
• Emergency fund – in a boring high-interest savings account.

What made a big difference was keeping joint goals transparent but still giving each other “fun money” autonomy. Helps reduce money tension and keeps both parties motivated toward the long game.
