What Would It Take to Give Away 10% of Your Income Every Year?

Most spending benefits the person doing the spending. Charitable giving is different. People give because they believe in a cause, want to help others, improve their community, honor a loved one, or simply because generosity brings satisfaction. Many religious traditions encourage giving as well. In the Judeo-Christian tradition, a 10% tithe has been a longstanding standard. However, plenty of people without a religious commitment approach giving through philanthropy, civic responsibility, gratitude, or a desire to leave the world better than they found it. Whatever the motivation, the question is worth asking: how much capital would it take to fund that level of giving year after year?

Giving While You’re Alive

Many people spend decades building wealth with the intention of helping others someday. A dedicated giving portfolio creates an opportunity to see the impact firsthand. You can watch the scholarship get funded, the church project completed, the family helped through a crisis, or the local animal shelter expand its work. For some donors, seeing the results becomes more rewarding than leaving a larger estate after they are gone.

The Tax Advantage of Giving

Retirees who itemize deductions may receive a charitable deduction for cash gifts. Donating appreciated stock can be even more efficient, allowing the donor to avoid capital gains tax while still receiving a deduction for the full fair-market value. For retirees over age 70½, qualified charitable distributions (QCDs) from an IRA can satisfy charitable goals without increasing taxable income and may reduce future required minimum distributions.

Timing matters as well. Some donors bunch several years of contributions into a single year to maximize deductions, then make grants gradually through a donor-advised fund. Others use unusually high-income years, such as after a business sale or Roth conversion, to offset part of the tax impact with charitable deductions. A well-structured gift can lower taxes, increase retirement cash flow, and direct more money to the causes the donor cares about.

What 10% Actually Looks Like in Dollars

Per capita disposable income hit $68,359 in Q1 2026, while the personal savings rate slid to nearly 4%. Against that backdrop, here is what a tithe looks like at three common household income levels:

• Household A ($50,000 income): $5,000 annually, or about $417 per month
• Household B ($100,000 income): $10,000 annually, or about $833 per month
• Household C ($150,000 income): $15,000 annually, or about $1,250 per month

People obsess over the percentage. Few ever calculate the capital required to write those checks indefinitely.

The Self-Funding Giving Portfolio

A dedicated giving portfolio flips the equation. Instead of donating from earned income, you donate from a pool of assets that generates income. The principal stays intact. The dividends do the giving. Done well, the portfolio outlives you and keeps funding causes for decades, which is the difference between a single donation and an endowment.

Three Giving Levels at Four Yield Tiers

The math is mechanical: target divided by yield equals capital required.

The 3.5% tier is dividend-growth territory: blue-chip pharma like Johnson & Johnson (NYSE:JNJ), yielding 2.2% with 64 consecutive years of increases, and regulated utilities like NextEra Energy (NYSE:NEE), where management is targeting roughly 10% dividend growth through 2026. The 5% to 7% tier brings in net-lease REITs such as Realty Income (NYSE:O), yielding about 5.3% after its 670th consecutive monthly dividend, alongside preferred shares and high-dividend equity. The 10%-plus tier is business development companies like Ares Capital (NASDAQ:ARCC) at roughly 10.6%, and mortgage REITs like AGNC Investment (NASDAQ:AGNC) near 14%. With the 10-year Treasury at about 4.5%, every tier above it carries a risk premium.

The Legacy Multiplier

A one-time $10,000 gift funds one year of generosity. A $200,000 portfolio yielding 5% funds that same $10,000 every year, potentially for decades. Over 25 years, the second approach delivers $250,000 in giving from capital that still exists at the end. That is the legacy multiplier: the gift keeps giving long after the donor stops working, or stops living.

Why Lower Yield Often Wins Long Term

Consider Household B funding $10,000 in giving. A 3.5% portfolio with 7% annual dividend growth roughly doubles its payout every decade, so within 10 years the same capital funds about $20,000 of charity. A 10% portfolio with no growth still pays $10,000, but inflation erodes its real value, and principal can drift lower. For a giving portfolio, growing income often matters more than maximizing current yield. A charity receiving $20,000 a year ten years from now may benefit more than one receiving $10,000 forever.

When This Strategy Does Not Fit

A dedicated giving portfolio is not for everyone.

• Retirees living on a fixed nest egg may need that capital for healthcare and housing, not charity.
• Donors with appreciated stock often capture better tax outcomes by gifting shares directly through a donor-advised fund rather than selling and donating cash.
• Some causes are best served by a single large gift that funds a building or scholarship rather than a $5,000 annual drip.

Three Moves to Make This Week

1. Match the cadence. If you tithe monthly, weight the portfolio toward monthly payers like Realty Income and AGNC so dividends arrive when checks go out.
2. Run the 10-year comparison. Pull total returns for a dividend-growth name against a high-yield name to see how compounding diverges from current yield.
3. Use a QCD or donor-advised fund. If you are over 70.5, qualified charitable distributions from an IRA can fund giving pre-tax, stretching every dividend further.
