| Gift Amount | Rate | Deferral | Payment Years | Annual Payment |
|---|---|---|---|---|
| $50,000 | 5.80% | 5 years | 18 years | $2,900 |
| $100,000 | 6.50% | 8 years | 20 years | $6,500 |

Formula Used
Annual payment = Gift amount × Annuity rate
Periodic payment = Annual payment ÷ Payments per year
Present value at payment start = Periodic payment × [1 − (1 + periodic discount rate)−number of payments] ÷ periodic discount rate
Present value today = Present value at payment start ÷ (1 + annual discount rate)deferral years
Estimated charitable remainder = Gift amount − Present value today
Estimated tax savings = Estimated deduction × Marginal tax rate
Net donor cost = Gift amount − Estimated tax savings
How to Use This Calculator
Enter the planned gift amount first. Add the annuity rate offered for the arrangement. Enter the number of years before payments begin. Then add the expected payment period and frequency.
Use the discount rate to estimate present value. Add tax assumptions for a basic donor cost estimate. Include reserve growth and admin fees for a broader planning view. Press the calculate button to view results above the form.

Deferred Gift Annuity Planning Guide
Overview
A deferred gift annuity blends charitable intent with future income planning. The donor makes a gift now, while payments begin after a chosen waiting period. This delay can create a higher payment rate than an immediate arrangement. It can also increase the estimated charitable portion because payments are pushed into the future.
Key Inputs
This calculator helps compare the main moving parts. It asks for the gift amount, annuity rate, deferral period, expected payment duration, discount rate, and tax assumptions. These entries produce annual income, periodic income, total projected payout, present value of payments, estimated remainder, tax savings, and net donor cost. The figures are planning estimates, not legal, tax, or actuarial advice.
Deferral Impact
Deferral years matter because they change both timing and value. A longer delay usually lowers the present value of the annuity promise. That can leave a larger estimated charitable remainder today. However, the donor waits longer before receiving income. The best choice depends on income goals, life stage, and giving plans.
Rate and Value
The annuity rate also has a strong effect. A higher rate increases annual payments and total payout. It also increases the present value of the income stream. That can reduce the remaining charitable value. A lower rate does the opposite. The calculator shows these relationships clearly.
Discount Assumptions
Discount rate is another important assumption. It converts future payments into today’s value. Higher discount rates make distant payments worth less today. Lower rates make them worth more. Because small changes can affect results, users should test several assumptions.
Tax Planning
Tax fields are included for simple planning. The estimated deduction percentage and tax rate produce a basic tax savings estimate. This helps show net donor cost. Real deductions may depend on age, timing, rates, charity rules, and local tax rules.
Scenario Testing
For stronger analysis, compare conservative, moderate, and optimistic cases. Keep the gift amount constant first. Then adjust only one field at a time. This method makes differences easier to understand. It also helps donors see tradeoffs between income security, charitable impact, and long term timing for each scenario.
Final Review
Use the results as a discussion tool. Save the CSV for records. Export the PDF for a meeting. Then review the plan with a qualified advisor and the receiving charity before making any gift commitment.
FAQs
What is a deferred gift annuity?
It is a charitable giving arrangement where a donor gives assets now and receives fixed payments later. Payments begin after a selected deferral period.
Why does deferral matter?
Deferral delays payments. This can raise future payment potential and reduce the present value of the payment promise, which may increase estimated charitable value.
Is the result a final tax deduction?
No. The deduction shown is only an estimate. Actual deductions depend on tax law, age, rates, timing, and charity calculations.
What does discount rate mean?
The discount rate converts future payments into today’s value. It helps estimate what the annuity payment stream is worth now.
What is net donor cost?
Net donor cost is the gift amount minus estimated tax savings. It gives a simple view of the donor’s after-tax cost.
Can I use monthly payments?
Yes. Select monthly frequency. The calculator divides the annual payment into twelve estimated periodic payments.
Why include admin fees?
Admin fees help estimate the charity’s long-term cost. They reduce the projected net charitable value in this planning model.
Should I rely on this calculator alone?
No. Use it for planning and comparison. Always confirm figures with the charity, a tax advisor, and legal counsel.
