Top ways to close the gap
All three programs, side by side
Every price above is the smaller of two ceilings: what your projected savings can close on (down payment + closing costs), and what your income can sustain at 25% of take-home pay — the same target share the Home Affordability calculator uses. Whichever is lower is what actually limits you, and it's called out on each card above.

Educational estimate, not financial advice. FHA upfront (1.75%) and annual (0.55%) mortgage insurance premium rates, and the life-of-loan MIP rule below 10% down, follow mortgage-info.com's 2026 FHA MIP chart and themortgagereports.com's FHA MIP cancellation guide. High-yield savings APY reflects NerdWallet's "Best High-Yield Savings Accounts of September 2026." Closing-cost range follows LendingTree's 2026 mortgage closing-cost explainer; this tool uses 3% as a single default. Conventional rate, property tax, insurance, and PMI fallbacks are reused verbatim from the Home Affordability calculator so every tool on this site agrees on the same baseline assumptions.

How this calculator works

Three ways to buy the same house — and which one you'll reach first.

"How much do I need to save for a house?" has three honest answers, because there are three common ways to finance one. This calculator runs your target price through all of them at once — conventional with 20% down (no mortgage insurance), conventional with 10% down (temporary PMI), and FHA with 3.5% down (mortgage insurance for the life of the loan) — and tells you which path gets you into the house soonest, and what it costs you every month once you're in.

Two ceilings, checked separately

Each program has two limits, and you hit whichever comes first.

cash needed = price × (down % + closing %)
months to goal = months until savings × (1 + APY/12)m + weekly × 52/12 × … ≥ cash needed
income ceiling: PITI + MI ≤ 25% of take-home

Why FHA usually wins on time and loses on cost

At 3.5% down, the cash needed is roughly a fifth of the 20%-down amount, so FHA is almost always the fastest path in. The price is FHA's mortgage insurance premium, charged for the life of the loan at that down payment — it only disappears when you refinance or sell. Conventional PMI at 10% down costs more per month at first but cancels itself once you reach 20% equity. The program cards show the estimated payment under each, and the PMI guide explains the removal rules in detail.

The "best path" is the reachable program with the shortest time to goal. If every program is income-capped, the calculator says so plainly and the suggestions shift to what actually moves that ceiling.

Is 3.5% down really enough?

Enough to qualify, yes — FHA allows it with a 580+ credit score. Whether it's enough for you is the question the report card asks: a smaller down payment means a bigger loan, a higher payment, and mortgage insurance you can't cancel. Run your real numbers through the Home Affordability calculator once you have a target.

Why does my savings account rate matter?

Over two or three years, 4% versus 0.5% on a growing balance is worth a few months of contributions. Most big banks pay near zero; online high-yield savings accounts routinely pay 4%+. The rate is editable, so use whatever yours actually pays.

What are closing costs, and why 3%?

Lender fees, title, escrow, prepaid taxes and insurance — typically 2–5% of the price, paid on top of the down payment. 3% is a middle estimate; the closing-costs guide breaks down every line on the disclosure so you can tighten it.

Can I count a gift or a first-time buyer program?

Add gift money to your current savings. Down payment assistance programs vary by state and city — there are thousands — and the first-time buyer guide explains how to find the ones you'd qualify for, which can shorten every path here.
