Securities exam calculators
Five interactive calculators for the math that mutual-fund and variable-product exams test: share-class economics, 12b-1 drag, breakpoint reconciliation, VA surrender, and NAV/POP. Use them to drill the patterns until the relationships feel automatic, then carry them into the SIE, Series 6, 7, or 65.
Share Class Comparison
Side-by-side A vs B vs C total-cost analysis over your chosen holding period. Includes front-end load drag, 12b-1 fee compounding, CDSC liquidation, and Class B conversion.
SIE, S6 (Function 3 ~50%), S7, S65 Open calculator → calc.12b1_drag12b-1 Fee Impact
How much a 0.25% vs 1.00% 12b-1 fee actually costs you over 10, 20, or 30 years. Shows dollar drag and the gap between gross and net of fees.
S6 Function 3 (heavy), SIE, S7 Open calculator → calc.breakpointMutual Fund Breakpoint
How much more you need to invest to hit the next breakpoint, plus Letter of Intent (LOI) and Rights of Accumulation (ROA) math. Common breakpoint schedules built in.
S6 Function 3, S7, SIE Open calculator → calc.surrenderVariable Annuity Surrender
What you owe if you withdraw from a variable annuity in year X. Free-withdrawal allowance, declining surrender schedule, and the net you actually receive.
S6 (VA suitability), S7, SIE Open calculator → calc.nav_popNAV / POP / Sales Charge
Compute Public Offering Price from NAV and sales load. Shows the sales charge in both dollars and percent, plus the rounded POP a Class A buyer actually pays.
SIE, S6 Function 3, S7, S65 Open calculator →Mutual fund mechanics (share classes, 12b-1 fees, breakpoints, NAV/POP) and variable-annuity surrender economics sit on every license that covers investment-company products. The depth and weighting shift by exam, but the underlying math does not change.
| Exam | Coverage | Notes |
|---|---|---|
| SIE | Medium | Survey-level coverage of share classes, fees, and pricing fundamentals |
| Series 6 | High | Function 3 is ~50% of the exam. These calculators line up with the most-tested concepts. |
| Series 7 | High | Same content, broader test surface (also adds direct-participation programs and options) |
| Series 65 | Medium | Investment products + suitability; NAV/POP and share-class economics appear in the product chapter |
Every securities license is closed-book. Prometric gives you a basic on-screen calculator (add, subtract, multiply, divide, square root) and nothing else. The point of these tools is not to use them on exam day. It is to internalize the math relationships so when you see a multiple-choice question asking which share class is cheapest at year 8 with a $25,000 investment, you do not have to recompute from scratch. You have already seen the pattern.
The most efficient study flow: read the related article in your exam hub (SIE, Series 6, Series 7, or Series 65), then load the calculator, then run the same scenario 5 times with different inputs. Watch the winner change as you cross the breakpoint, the holding period, or the conversion year. After ~10 minutes per calculator the patterns lock in.
Which exams are these calculators built for?
The underlying math is tested across the SIE, Series 6, Series 7, and Series 65. Series 6 Function 3 (Provides Information, Makes Recommendations, Transfers Assets, Maintains Records) is roughly 50% of that exam and the single heaviest test of these concepts, but the same share-class economics, breakpoint mechanics, VA surrender rules, and NAV/POP formulas show up on every license that covers mutual fund and variable-product mechanics.
Are these calculators on the actual exam?
No. The exams test the math behind them, not interactive tools. The SIE, Series 6, 7, and 65 are all closed-book with no calculator other than the on-screen basic Prometric calc (add, subtract, multiply, divide, square root). These pages help you internalize the relationships so the math is automatic by exam day: which share class is cheapest over a given horizon, how much 12b-1 drag actually costs, what surrender charge applies in year 4 of a 7-year schedule, and how a sales load creates the NAV-to-POP spread.
Why does CertFuel build these instead of pointing to FINRA Fund Analyzer?
FINRA's Fund Analyzer is the gold-standard real-world tool, but it is built for fund-shopping, not for exam prep. These calculators are stripped down to the inputs the exams actually test, with a 'where this is tested' section under each one. Use FINRA Fund Analyzer for client work; use these for learning the patterns the exam will test.
Are the default assumptions realistic?
Yes. Defaults match common exam scenarios: $25,000 investment (just under most A-share $50K breakpoint), 7% expected annual return, 10-year horizon, 5% front-end load for Class A, 1.00% 12b-1 for Class B/C, and the 7-year declining surrender schedule (7/6/5/4/3/2/1/0%) for variable annuities. You can change every input.
Do these work on mobile?
Yes. The calculators use plain HTML inputs and vanilla JavaScript, so they work in any browser on phone, tablet, or desktop. No JavaScript framework, no app install.
Can I use these on the actual exam?
No. The SIE, Series 6, 7, and 65 are administered by Prometric in a locked-down testing environment with only the built-in on-screen calculator. The purpose of these pages is to practice the math beforehand so the relationships are second-nature when the multiple-choice question appears.
