Navy Federal Home Equity Line of Credit: what $50,000 costs by the day you sell

In our illustration, take $50,000 from a $500,000 home through Navy Federal Credit Union and sell in year 10: the model produces $40,000 more than you received, an annualized modeled cost of 8.3%. Sold in year 5 the cost is $20,000.

That uses the lowest APR the page publishes, 8%, held flat, which is an advertised minimum.

What does the provider publish?

What does it cost by the day you sell?

The table applies the published terms to one scenario, the same one used for every product on this site. No upfront fee is published, so none is added.

Sold in	Paid along the way	Owed at sale	Upfront fees	Total cost	Annualized

How that is worked out

home value today = $500,000; cash taken = $50,000 (10% of value) home value in year N = $500,000 x 1.03^N (3% a year, every product) HEI, share of value = multiplier x 10% x home value in year N HEI, principal + share = $50,000 + share x (value in year N - adjusted starting value) HEI cap = $50,000 x (1 + cap/12)^(12N) where the provider publishes a cap HELOC illustration = interest-only using the lowest published APR as a rate proxy, then amortized home equity loan example = amortized using the lowest published APR as a rate proxy total cost at sale (N) = payments made + balance or payoff owed at sale - $50,000 + upfront fees annualized cost = the yearly rate that turns the cash received into everything paid back

Every rate is the lowest the provider publishes, so where a page says “as low as” the figure is an illustrative starting scenario. An “up to” fee is modeled at its stated maximum; the actual fee may be lower. APR is used as a proxy for the payment rate when no separate note rate is published. Variable rates are held flat. Eligibility, unpublished charges, taxes and insurance are excluded. These figures are neither quotes nor guaranteed lower bounds. Read the method.

Who owns it?

Who owns this company is not stated on its own site, and we could not confirm it from a primary source. We have left it blank rather than repeat what other sites say.

Where this leaves you

If rates rise, this figure does not hold: it uses 8% flat, and the published rate is variable.
If you draw less than the full amount, the interest falls in proportion; the table assumes the whole line is drawn from day one.
If the year-10 cost is what matters, U.S. Bank works out at $30,425 on the same scenario — compare the two.
Do not decide yet if you do not know when you will sell: this product costs $12,000 at a sale in year 3 and $40,000 in year 10, and the right comparison is against your own sale year and home value, not ours.

Who this page is not for

This is not a review. We have not used Navy Federal Credit Union, we hold no opinion on its service, and nothing here is a recommendation or advice. It answers one question: what the published terms turn into by the day you sell.
