Bitcoin Loan Refinance Calculator
Pick who you borrow from today and who you're thinking of moving to. You'll get a full switching analysis: the rate change, any new origination fee, what early payoff costs at your current lender, and whether your Bitcoin actually has to change custody.

What would actually change
APX Lending (current) refinance terms
Fixed-rate terms run 3 to 60 months and are extendable with no origination or admin fees. Early repayment is capped at about three months of interest.
Arch (new) refinance terms
You can roll over or refinance from the dashboard at the end of your term, or any time without a prepayment penalty, at the prevailing rate. The origination fee (0.25%–1.49%, tiered by size) applies again on each new loan.
What “refinancing” a Bitcoin loan actually means
Refinancing a Bitcoin-backed loan means paying off your existing loan and opening a new one at current rates, either with the same lender or a different one. Unlike a mortgage refi, there's no property appraisal and usually no credit pull — the collateral is your Bitcoin, and the terms hinge on its value and your loan-to-value ratio. The mechanics that matter are different too: instead of closing costs and points, the cost centers are the new origination fee, any early-payoff terms on your current loan, and what happens to the custody of your coins.
Because your loan balance is fixed in dollars but your collateral value moves with Bitcoin's price, the right time to refinance is often driven as much by where the rate market sits as by how much your Bitcoin has appreciated since you borrowed.
The custody question: does your Bitcoin have to move?
This is the part most rate-comparison tools ignore, and it's the part that can make a “cheaper” lender not worth it. When you refinance, one of two things happens to your collateral:
- It stays put. If your current and new lender use the same qualified custodian (for example, both custody at Anchorage Digital), the new lender can pay off the old loan and the collateral is re-papered in place rather than sent on-chain. Less movement, less timing risk, fewer transfer fees. Confirm the lender supports an in-kind transfer rather than forcing a withdraw-and-redeposit.
- It moves.If the two lenders use different custodians or different custody models (a pooled lender vs a qualified custodian vs collaborative multisig), paying off the old loan releases your Bitcoin, which is then transferred and posted as collateral with the new lender. That means an on-chain transfer, a short window where the position is in motion, and dependence on the new lender's funding speed.
The calculator infers which case applies from each lender's published custody model and partners, and also flags a change in rehypothecation — moving from a lender that may re-lend your collateral to one that doesn't is a genuine reduction in counterparty risk, even if the rate is identical.
The two fees that decide whether it's worth it
A new origination fee — that you might otherwise avoid
Switch to a different lender and you almost always pay their origination fee on the new loan, anywhere from 0% to about 2% of the balance. The catch borrowers miss: refinancing in place with your current lender sometimes avoids it entirely. Some lenders refinance for free with no origination, prepayment, or renewal fee. Others re-charge their origination fee on every new term, so even staying put has a cost. The calculator puts the switch cost next to the stay cost so you can see the real difference, not just the headline rate.
Early payoff at your current lender
To refinance, you have to close the existing loan. Most Bitcoin-backed CeFi lenders advertise no prepayment penalty, so this is free, which is genuinely good news and worth confirming. But some have conditions: a minimum loan age before you can close, a small fee to repay in Bitcoin rather than cash, or an admin fee that applies in some regions and not others. The calculator surfaces your current lender’s stated early-payoff policy so a “free” switch doesn’t turn out to have a tail.
Reading the breakeven
The headline saving is the annual interest difference between your current rate and the new lender's rate on your balance. The breakeven is how long that saving takes to recoup the one-time switching cost (mainly the new origination fee). A lower rate with a 2% origination fee can take many months to pay for itself; a lower rate with no origination fee pays off immediately.
Two honest caveats baked into the numbers: the rate comparison uses each lender's lowest published APR as a representative starting rate, so your real quote may differ with size, LTV, and term; and an open, revolving credit line (no maturity) has nothing to “refinance” in the term sense — you can repay and close it whenever, so switching out of one is purely a rate-and-custody decision. The calculator flags that case when it applies.
Compare your refinance across every lender
