How This Calculator Works
Months to goal = log(1 + gap × monthly rate / savings) / log(1 + monthly rate). Interest earned = (savings × compound months) - gap. HYSA compounds monthly at stated APY/12.
Frequently Asked Questions
Minimum: 3% (conventional), 3.5% (FHA), 0% (VA/USDA). Recommended: 20% to avoid PMI. On a $400K home, 20% = $80,000.
Saving $1,500/month with modest interest: ~30 months. At $2,000/month: ~23 months. Use a HYSA earning 4-5% to accelerate growth.
20% avoids PMI (~$100-200/month extra). But putting 10% down and investing the rest can beat PMI cost if returns exceed mortgage rate.
High-yield savings account (HYSA) or money market fund for 0-2 year timeline. Short-term CDs or Treasury bills. Avoid stock market for near-term goals.
