Mortgage Calculator for First-Time Buyers
The first-time buyer's decision is rarely "can I afford the monthly payment" — it is which low-down-payment route to take and what each one quietly costs. The Federal Housing Administration route accepts 3.5% down and a credit score in the high 500s, and charges for that flexibility through mortgage insurance premium: 1.75% of the loan upfront plus an annual premium (0.55% for the most common case) that typically lasts the life of the loan. A conventional loan needs better credit and more cash — commonly 5% down — but its private mortgage insurance is cheaper and disappears once you reach 20% equity.
The calculator below is pre-set with the canonical FHA scenario: $300,000 purchase, 3.5% down, 30-year term at 6.5%, with the annual MIP modelled at 0.55%. Change any input and the payment updates instantly; the sections underneath trace what MIP costs over time, what cash you actually need at the table, and how the 28/36 guideline sizes the income behind this payment.
Below 20% of price, PMI applies.
Often 1-2% of home value yearly.
Typically 0.3-1.5% of loan.
Optional — see the payoff effect.

Private mortgage insurance, required below 20% down on conventional loans.
Estimates for conventional loans; taxes and insurance vary by location and coverage. Your lender's Loan Estimate is the binding figure — use this to sanity-check it.

The FHA route: 3.5% down and what MIP costs
The preset models the standard FHA purchase. The monthly total is principal, interest, the annual MIP, and escrowed tax and insurance — and the FHA's insurance is the part that surprises first-time buyers, because it comes twice:
| FHA — the preset | Conventional alternative | |
|---|---|---|
| Minimum down | 3.5% — $10,500 | 3-5% — $9,000-15,000 |
| Upfront fee | 1.75% of loan (≈$5,066), usually financed | None |
| Annual insurance | 0.55% MIP — $132.69/mo, often for life of loan | PMI ≈ $100-150/mo, cancels at 20% equity |
| Credit floor | 580 for 3.5% down (500-579 needs 10%) | 620+, best pricing at 740+ |
| Monthly payment (preset rates) | $2,312.52 | similar today, drops when PMI cancels |
The real cash to close is double the down payment
First-time budgets fail on the cash column, not the monthly one. The down payment is only the headline: closing costs — lender fees, title, appraisal, prepaid escrows — typically add 2-5% of the purchase price, and on a $300,000 purchase that is $6,000-15,000 on top of the $10,500 down payment. The realistic all-in cash range for this scenario is $17,000-25,000.
Three levers soften it: seller concessions (FHA allows sellers to credit up to 6% toward your closing costs), state and local down-payment-assistance programs that can fund part or all of the down payment for qualifying buyers, and negotiating credits in the offer itself. Our closing cost calculator itemizes the second number so the cash-to-close figure is planned rather than discovered a week before signing.
How much house: the 28/36 lens on this payment
The preset payment of $2,312.52 a month includes escrowed tax and insurance, which first-time budgets routinely forget. Under the 28/36 guideline lenders underwrite with — housing costs at or below 28% of gross income, all debts at or below 36% — that payment wants roughly $8,300 gross monthly income, about $99,000 a year with no other debts. Every $500 of existing debt payments (car, student loans, cards) pushes the required income materially higher under the 36% test.
Run your own income through our home affordability calculator to see which limit binds for you, and treat the result as a floor for comfort rather than a ceiling set by the bank — the guideline decides what you can borrow, not what you can live with.
Frequently asked questions
- How much down payment does a first-time buyer actually need?
- Less than the famous 20%. FHA accepts 3.5% down with a 580 credit score; conventional loans go as low as 3% through first-time-buyer products like HomeReady and Home Possible; VA loans require nothing for eligible veterans. On a $300,000 purchase that is $9,000-15,000 down instead of $60,000 — the 20% figure is a PMI-avoidance strategy, not a requirement.
- What is MIP and how is it different from PMI?
- Both are mortgage insurance, charged because the down payment is small. FHA's version is MIP: 1.75% of the loan upfront (usually financed) plus an annual premium — 0.55% in the preset — that generally lasts the life of the loan. Conventional PMI has no upfront fee, costs about the same monthly at these loan sizes, and cancels automatically once you reach 20% equity. Over a long hold, conventional usually wins; for a thinner credit file or thinner cash, FHA is often the door that opens.
- Do I need 20% down to avoid being rejected?
- No. Most first-time buyers put down well under 20%, and lenders approve low-down-payment loans routinely — the insurance premium is how they price the risk. Putting 20% down removes the insurance and shrinks the payment, but delaying years to save it while prices and rents rise usually costs more than the PMI would have.
- What credit score do I need for an FHA loan?
- 580 for the 3.5% minimum down payment; between 500 and 579 you can still qualify but must put 10% down. Below 500, FHA is not available. Conventional pricing improves noticeably at 700 and again at 740, so if your score is near a threshold, a month or two of cleanup can change the payment more than shopping lenders does.
- Are there programs that help first-time buyers with the down payment?
- Yes — nearly every state runs down-payment-assistance programs offering grants or forgivable loans to income-qualified first-time buyers, and many pair with below-market first mortgages. Combine assistance with FHA's 3.5% or a conventional 3% product and some buyers close with almost none of their own cash. Your state housing finance agency's website lists the current programs.
- What income do I need for a $300,000 house?
- For this preset's $2,312.52 monthly payment, the 28% guideline points to about $8,300 gross monthly — roughly $99,000 a year with no other debts. That includes the escrowed tax and insurance most quick calculators omit. Carry $500 of debt payments and the 36% back-end test raises the bar further; the affordability calculator shows both limits for your exact numbers.
