Best Banks in Colorado
Top regional banks serving Colorado include:
- FirstBank (Lakewood HQ
- ~95 branches
- largest CO-headquartered bank with $26.5B assets)
- Alpine Bank (Colorado since 1973
- employee-owned)
The largest bank by presence in Colorado is Wells Fargo (118 branches, largest deposit share); FirstBank is the largest Colorado-headquartered bank ($26.5B assets, ~95 branches) — note PNC is acquiring FirstBank which will make PNC the 2nd-largest in CO.
Best for checking: FirstBank — no minimum balance, no monthly maintenance fees on most checking accounts, 95 branches statewide
Best for savings: Canvas Credit Union — 5.00% APY on first $2,000 in savings; among online banks, Varo Bank offers 5.00% APY on balances up to $5,000 with qualifying deposits
Regional banks often combine local branch access with competitive accounts, which is why they tend to score well with Colorado customers. Top high-yield savings accounts available to Colorado residents pay around 3.85% to 5.00% (Colorado Federal Bank at 3.85%; Canvas CU at 5.00% on first $2K; national online banks up to 4.03%-5.00%) in June 2026.
National Banks Available in Colorado
If you want a big branch and ATM network, the major national banks all operate in Colorado:
- Wells Fargo (118 branches in CO)
- Chase (109 branches)
- U.S. Bank (103 branches)
- BMO Bank (68 branches)
National banks are convenient but rarely pay the best savings rates — pair one with a high-yield online account for the best of both.

- Ent Credit Union (largest CU in Colorado
- based in Colorado Springs)
- Bellco Credit Union (Denver-based
- strong auto/home loans)

Other Colorado notes: Colorado has an unusually strong regional banking landscape — FirstBank (largest CO-headquartered bank) is being acquired by PNC Financial, which will vault PNC from 12th to 2nd largest in the state. The state has a robust credit union culture led by Ent CU (the largest). Alpine Bank is notable as employee-owned. The mountain and Western Slope regions are well-served by U.S. Bank. Colorado Federal Savings Bank offers competitive local savings rates (3.85% APY). Canvas CU stands out with 5.00% APY on initial savings balances.
Checking, Savings, and CDs Explained
Most Colorado banks offer the same core accounts:
- Checking — for everyday spending and direct deposit. Look for no monthly fee.
- Savings — for your emergency fund. Online banks pay the highest rates.
- Money market — a savings account with limited check-writing.
- CDs — lock money for a set term in exchange for a higher fixed rate.
A common setup for Colorado residents is a no-fee checking account at a local bank plus a high-yield savings account at an online bank.
How Bank Sign-Up Bonuses Work in Colorado
Banks pay cash bonuses — often $100 to $400 — to win new customers. To earn one you typically open a new checking or savings account, then meet a requirement such as receiving a set amount of direct deposit or keeping a minimum balance for a few months. The bonus is usually paid within 90 days. As long as you would open the account anyway, it is essentially free money. We track current offers open to Colorado residents on our listings page.
