Simple Interest Calculator United States 2026
Simple interest, and what it becomes when you compound it, add a monthly deposit, pay tax on it or hold it long enough for inflation to matter — with the balance drawn year by year.
Simple interest is principal times rate times time, and it is the one form of interest that never earns on itself: 10,000 at 6% earns 600 a year whether it is the first year or the tenth.

How the simple interest works
Simple interest is principal times rate times time, and it is the one form of interest that never earns on itself: 10,000 at 6% earns 600 a year whether it is the first year or the tenth. Choose a compounding frequency and the arithmetic changes completely — each period's interest joins the balance and earns in the next, so the same rate over the same term returns more the more often it compounds, and the gap widens with time rather than staying proportional. That difference is the whole reason a quoted rate means little without the compounding beside it. A regular deposit is added at the start of each period so it earns for that period, which is the convention a savings account uses. Tax comes off the interest, not the balance: interest is ordinary income in all three markets, taxed at your marginal rate rather than at a savings rate, and the after-tax line is what actually accrues to you. The real value discounts the final balance by inflation over the term — the number that answers whether the money grew or merely kept its place, and at a 6% return against 3% inflation it is roughly half of what the nominal figure suggests.
Formula: Simple: I = P × r × t · Compound: A = P(1 + r ÷ n)^(n × t) · real value = A ÷ (1 + i)^t
United States Simple Interest Notes
US simple-interest examples are useful for promissory notes, short-term loans, classroom finance, late-payment calculations, and non-compounding savings checks.
Because interest is calculated only on the original principal, this is different from APY or compound-interest examples used by most deposit accounts.
Use this USD version when the agreement does not compound and you need a clear interest amount for a chosen number of days, months, or years.
For CDs, savings accounts, or investment growth, compare this result with compound-interest or savings-goal calculations.
US setup: this simple interest is tuned for dollar-denominated scenarios, American payroll and tax references, state-by-state cost differences, and the finance terms people see in lender, employer, or IRS-facing documents.
The page keeps US language in place where it is relevant, including IRS, federal withholding, FICA, 401(k), sales tax, miles, APR, down payment, paycheck, state tax, and USD totals.
Treat the answer as a United States estimate; before acting, compare it with provider disclosures, state rules, federal guidance, lender underwriting, payroll settings, or advice from a qualified professional.
Simple interest = Principal × Rate × Time. Interest does not compound — it remains flat.

Your result shows the projected growth or return based on the rate, contribution, and time period you entered — using standard compound or simple interest formulas.
What to do with itUse this to set savings targets, compare investment options, or understand the impact of starting earlier. Adjust the rate and timeframe to model optimistic and conservative scenarios.
What it is notNot a guaranteed return. Actual investment outcomes depend on market conditions, fees, taxes, and timing that cannot be predicted with certainty.
AccuracyUses standard financial formulas with the inputs you provided. Calculator arithmetic runs in your browser; the calculator code does not submit your figures to GlobalCalc to obtain a result.
Savings and investment results are dominated by three factors: the rate of return, the time horizon, and regular contributions. Compounding amplifies all three over time.
Compound growthReturns on returns accelerate growth over time. The difference between 5% and 7% over 20 years is much larger than the 2% gap suggests — compounding is non-linear.
Regular contributionsAdding even small regular amounts dramatically increases the final balance. $100/week invested at 7% for 20 years grows to over $110,000 in contributions and $110,000+ in returns.
Time horizonStarting 5 years earlier often produces a larger final balance than doubling your contribution rate. Time is the most powerful variable in savings calculations.
To improve your savings outcome, focus on starting earlier, increasing contributions, and minimising fees and tax drag on returns.
Start now, increase laterStarting with a small amount today and increasing over time beats waiting to start with a larger amount. Time in the market matters more than timing the market.
Minimise feesA 1% annual fee on a $100k balance costs $1,000/year and compounds against you. Compare fee structures across savings and investment products.
Use tax-advantaged accounts401(k)s, IRAs, and tax-advantaged accounts reduce the drag of tax on your returns — letting more of the growth compound for you.

Simple interest formula
Simple Interest = Principal × Rate × Time (P × R × T). Interest is calculated only on the original principal — it never compounds. A $10,000 loan at 5% for 3 years: SI = $10,000 × 0.05 × 3 = $1,500.
| Principal | Rate | Years | Simple interest | Total repaid |
|---|---|---|---|---|
| $5,000 | 5% | 2 | $500 | $5,500 |
| $10,000 | 5% | 3 | $1,500 | $11,500 |
| $20,000 | 7% | 5 | $7,000 | $27,000 |
| $50,000 | 4% | 10 | $20,000 | $70,000 |

Simple vs compound interest — the difference over time
Why compound interest grows faster
With compound interest, each period's interest is added to the principal and then earns interest itself. With simple interest, the same dollar amount is added each period.
| Time period | $10k at 5% simple | $10k at 5% compound (annual) |
|---|---|---|
| 1 year | $10,500 | $10,500 |
| 5 years | $12,500 | $12,763 |
| 10 years | $15,000 | $16,289 |
| 20 years | $20,000 | $26,533 |
| 30 years | $25,000 | $43,219 |
The longer the period, the greater the advantage of compound interest. At 30 years, compound interest produces 73% more wealth than simple interest at the same rate.
When it's usedWhere simple interest is commonly used
Practical applications
Simple interest is used for: short-term personal loans (some pay-day and personal lenders), car loans (some dealer finance), government bonds, CDs that calculate interest on the initial deposit only, and some bridging loans.
When savings accounts use compound interest
Most US savings accounts compound monthly or daily — meaning your interest earns interest. Even if the rate appears the same as a simple interest calculation, the compounding effect means you actually earn slightly more. Always check whether a rate is simple or compound (effective annual rate).

Simple interest formula — P × R × T Principal × Rate × Time
Simple interest is calculated as: SI = P × R × T, where P is the principal, R is the annual rate (as a decimal), and T is the time in years. The interest amount is the same every period — it does not compound.
| Formula | SI = P × R × T |
|---|---|
| P = Principal | Initial amount |
| R = Rate | Annual rate as decimal (5% = 0.05) |
| T = Time | In years |
| Example | $10k × 0.05 × 3 = $1,500 |
| Total amount | A = P + SI = $10k + $1,500 = $11,500 |
- vs compound interest SI is fixed; compound grows
- Monthly equivalent Annual SI ÷ 12
- Daily equivalent Annual SI ÷ 365
- When is SI used? Short-term loans, auto financing, bills
- Simple vs compound (10yr) $5k vs $6,289 at 5%
When is simple interest used — practical examples Short-term loans and auto financing
Simple interest is used in: short-term personal loans, most auto loans, installment agreements, government bonds, and short-term bridge loans. Most long-term savings accounts and mortgages use compound interest.
| Short-term personal loans | Often simple interest |
|---|---|
| Some car loans | Dealer finance sometimes SI |
| Installment financing | Retail finance often SI |
| Government bonds | Coupon payments are SI |
| Mortgages? | Compound — interest compounds monthly |

Simple Interest = Principal × Rate × Time (P × R × T). Where rate is expressed as a decimal (5% = 0.05) and time is in years. Total amount = Principal + Simple Interest.
What is the difference between simple and compound interest?
Simple interest is calculated only on the original principal — the interest amount is the same each period. Compound interest adds each period's interest to the principal, so subsequent interest is calculated on a growing balance. Over time, compound interest produces significantly more growth.
Do US banks use simple or compound interest?
Most US savings accounts and CDs use compound interest (calculated daily or monthly). Most personal loans use compound interest charged monthly. Some short-term loan products and bonds use simple interest. Always check the product disclosure statement.
When is simple interest better for the borrower?
Simple interest loans can be cheaper than compound interest loans at the same rate if the loan is repaid early — because interest does not accumulate on unpaid interest. This is most relevant for short-term loans and early repayment scenarios. Sources
