  • Read IP cook time + total wall-clock.

About this calculator

Slow cookers run at sub-boiling temps (190-210 °F), so even "fast" 4-hour slow-cooker recipes stretch to all-day equivalents. Instant Pots reach 240 °F under pressure, compressing time 6-12×. A pot roast on LOW for 8 hours becomes 40 minutes IP. The catch: IP pressurization takes ~15 min wall-clock, plus optional 10-min natural release. So the real wall-clock comparison is ~70 minutes vs. 8 hours — still a huge time savings, but be honest about pressurize time when planning.

Frequently asked

Why is LOW slower than HIGH besides the temp?+
LOW holds ~190 °F vs. HIGH ~210 °F. The 20 °F gap roughly halves cooking time per the Q10 collagen rule (rate doubles per 10 °C).
Are pressure-cooked dishes the same as slow-cooked?+
Texture differs slightly — slow cookers do longer collagen breakdown at lower temp; IP is faster but slightly rubberier on lean meats. For tough cuts both work great.
Can I "double" with the IP?+
No — recipes scale by ingredient mass, not time. Doubling beef stew is still 30 min IP, just with longer pressurize-up.
Slow-cook function on the IP?+
IP's slow cook mode is weaker than a real slow cooker — runs cooler. If you slow-cook in the IP, add 25-50% time vs. a Crockpot recipe.
What about searing first?+
IP's sauté function = stovetop sear in the same pot. 5-10 min extra wall-clock; usually worth it for flavor.
