How the math works
SEP-IRA contributions are limited to 25% of net self-employment income (adjusted) or $69,000 (2024), whichever is less. The effective rate works out to about 18.6% of gross SE income due to the SE tax deduction.
If you have employees, you must contribute the same percentage of their compensation. This can make a Solo 401k more cost-effective for solopreneurs.

How this calculator works
What this page estimates
This SEP-IRA Contribution Calculator is built to give a quick, browser-based estimate for sep-ira contribution. Calculate the maximum SEP-IRA contribution for self-employed individuals and small business owners. See 2024 limits and estimated tax savings. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the sep-ira contribution result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this sep-ira contribution estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
What is the 2024 SEP-IRA limit?
The lesser of 25% of net compensation (for SE, ~18.6% effective) or $69,000. There are no catch-up contributions for SEP-IRAs.
Can I have a SEP-IRA with employees?
Yes — but you must contribute the same percentage of compensation for all eligible employees. This can make a Solo 401k more attractive for solopreneurs without employees.
When is the SEP-IRA contribution deadline?
You can contribute up to the tax filing deadline including extensions (October 15 for individuals). This makes it useful for last-minute tax planning.
SEP-IRA vs. Solo 401k?
SEP-IRA is simpler to set up and has no annual filing requirements. Solo 401k allows higher contributions at lower incomes due to the employee elective deferral.
