Three household jobs. One primary calculator each.
01
Build the housing payment
A rate quote is principal and interest only. Add tax, insurance, and HOA so the monthly cash leaving the account is honest before you bid.
Open mortgage calculator →02
See compound growth clearly
Savings and investments grow on prior interest, not just the starting principal. Model contribution timing so the curve matches how you actually save.
Open compound interest calculator →03
Sketch the tax bill
Marginal brackets are not your blended rate. Estimate federal liability with filing status and deductions before you treat gross pay as spendable.

Gotchas before you commit money
Short warnings with a calculator handoff.
P&I is not the housing payment
Lenders quote principal and interest. Households pay tax, insurance, and often HOA too. Build the full monthly before you stretch the purchase price.
Mortgage →APR and APY are different quotes
APR ignores compounding; APY includes it. Comparing a loan APR to a savings APY without converting mixes two definitions.
Interest →Early amortization is mostly interest
Extra principal early in the term saves more total interest than the same extra payment late. Read the schedule before you decide when to prepay.
Amortization →Marginal tax is not effective tax
Crossing a bracket only taxes the dollars above the threshold at the higher rate. Your blended effective rate stays lower than the top bracket.
Income tax →Related hubs
