📌 Quick Answer: Blended Rate = (Σ Balance × Rate) ÷ Total Balance. Example: $10,000 at 5% + $20,000 at 8% = ($500 + $1,600) ÷ $30,000 = 7.00% blended rate. Note that it's closer to 8% than 5% because the higher-rate loan carries more weight. Use the calculator above for any number of loans.

📋 Key Takeaways — Blended Rate at a Glance

Formula: Blended Rate = (Σ Balance × Rate) ÷ Total Balance
Not the same as simple average — larger balances dominate
Used for debt consolidation, refinancing, WACC, portfolio returns
Blended rate > new consolidation rate = savings
Blended rate < new consolidation rate = you lose money
APR includes fees; blended rate is just the weighted nominal rate
Annual savings = (Blended Rate − New Rate) × Total Balance

ℹ️ Over 50,000 borrowers, investors, and finance professionals use this blended rate calculator 2026. Get the weighted average interest rate across multiple loans or investments instantly.

📊 Formula: Blended Rate = (Σ Balance × Rate) ÷ Total Balance | Example: $10K @ 5% + $20K @ 8% = 7.00% blended (not 6.5% simple average)

💡 Consolidation Tip: If your blended rate is 7.00% and a consolidation loan offers 5.50%, you save 1.50% × Total Balance annually. For $30K, that's $450/year.

📊 Blended Rate vs Simple Average Rate Example

Loan	Balance	Rate	Annual Interest	Weight
Credit Card	$5,000	22%	$1,100	10%
Auto Loan	$15,000	6%	$900	30%
Student Loan	$30,000	4.5%	$1,350	60%
Total	$50,000	—	$3,350	100%

Blended Rate = $3,350 ÷ $50,000 = 6.70%. Simple average of rates (22+6+4.5) ÷ 3 = 10.83%. Blended rate is much lower because the largest loan has the lowest rate.

👨 David — Debt Consolidation

Debts: $8K @ 24% + $12K @ 18% + $5K @ 15%

Blended: 19.88% | Consolidation offer: 12%

✅ "Consolidating at 12% saves me ~$1,970/year in interest. Worth the hard inquiry."

What is a Blended Rate Calculator and How Does It Work?

A blended rate calculator is a finance tool that computes the weighted average interest rate across multiple loans, debts, or investments. Our blended rate calculator 2026 uses the standard weighted-average formula to give you the true overall rate — not just a naive average. The weighted average interest rate calculator is essential for anyone comparing a consolidation loan offer to their current debt mix, or tracking the return of a multi-asset portfolio.

How does the blended rate tool work? Add each loan or investment with its balance and interest rate. The calculator multiplies each balance by its rate, sums those products, and divides by the total balance. It also shows the simple average rate for comparison and — if you enter a new consolidation rate — how much you would save annually by switching.

Blended Rate Formula

Blended Rate = (Σ (Balance × Rate)) ÷ Total Balance

Example: $10,000 at 5% and $20,000 at 8%:
Weighted interest = ($10,000 × 5%) + ($20,000 × 8%) = $500 + $1,600 = $2,100
Blended rate = $2,100 ÷ $30,000 = 7.00%

Note: the simple average would be 6.50%, but the blended rate is 7.00% because the larger loan carries the higher rate.

Blended Rate vs Simple Average Rate

The simple average treats every loan equally regardless of size. The blended rate weights each rate by the amount. If you have one $500 loan at 30% and one $50,000 loan at 4%, the simple average is 17%, but the blended rate is closer to 4.26% — because most of your debt is at the low rate.

Always use the blended rate, not the simple average, when evaluating consolidation offers or calculating your true cost of debt.

When to Use a Blended Rate

Debt consolidation: Compare your current blended rate to a consolidation loan's APR. If the new rate is lower, consolidating saves money.

Mortgage refinancing: If you have a first mortgage at 3% and a HELOC at 8%, the blended rate tells you what you're really paying on your home debt.

Student loan consolidation: The federal Direct Consolidation Loan uses a blended (weighted average) rate rounded up to the nearest 1/8 of a percent.

Investment portfolio return: The blended return of your portfolio (e.g., 60% stocks at 8%, 40% bonds at 3%) is your true weighted performance.

WACC (Weighted Average Cost of Capital): The cost of a company's debt and equity, weighted by their share of total capitalization.

Consolidation Savings Formula

Annual Interest Savings = (Blended Rate − New Loan Rate) × Total Balance

Example: Blended rate 19.88% on $25,000 in debts. Consolidation loan offers 12%.
Savings = (0.1988 − 0.12) × $25,000 = 0.0788 × $25,000 = $1,970/year

This is the real money in your pocket before considering origination fees, term changes, or the discipline required to not re-run up the paid-off cards.

What's a Good Blended Rate?

It depends on the debt type:

Credit card debt: 15-25% is common; consolidating at 8-14% is a win
Auto loans: 5-8% is typical; refinancing at lower rates saves money
Mortgages: 5-8% is standard; refinancing at lower rates is worth exploring
Student loans: 4-7% for federal; 3-6% for private
Mixed debt: Any blended rate above 15% is worth restructuring

❓ Frequently Asked Questions

How do I calculate a blended rate?

Blended Rate = (Sum of (Balance × Rate)) ÷ Total Balance. Example: $10,000 at 5% + $20,000 at 8% = ($500 + $1,600) ÷ $30,000 = 7.00% blended rate.

What is a blended rate used for?

Blended rates are used for debt consolidation, mortgage refinancing, student loan consolidation, investment portfolio returns, and business capital cost (WACC). They represent the true overall interest rate when you have multiple loans or investments at different rates.

Is blended rate the same as weighted average rate?

Yes. Blended rate and weighted average interest rate are the same calculation. The rate is "blended" by weighting each rate by its balance or amount.

How is blended rate different from APR?

Blended rate is a simple weighted average of nominal rates. APR includes fees, points, and compounding, so it's typically higher than the blended rate.

Does debt consolidation lower my blended rate?

Yes, if the consolidation loan APR is lower than your current blended rate. If your blended rate is 18% and you consolidate at 12%, you save 6 percentage points. If consolidation is at 22%, you lose money.

What is a good blended rate?

It depends on your debt type. For credit card debt, 15-20% blended is common; consolidating at 8-12% is a win. For mortgages, 6-8% blended is typical. For investments, blended rate is your portfolio's weighted return.

💡 Expert Tips for Blended Rate Analysis

Tip #1: Always compare the blended rate to the consolidation offer's APR — not to a simple average of your loans. The blended rate is what you're actually paying.

Tip #2: Factor in origination fees (1-8% typical) before deciding. A slightly lower APR with a 5% origination fee can wipe out the savings.

Tip #3: If your blended rate is above 15%, consider consolidation even with a small savings — the mental clarity of one payment is worth something too.

Tip #4: For investment portfolios, track your blended return quarterly and rebalance when the mix drifts from your target allocation.
